Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Consolidation: The consolidated financial statements include the accounts of Moog Inc. and all of our U.S. and foreign subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
	Fiscal Year: Our fiscal year ends on the Saturday that is closest to September 30. The consolidated financial statements include 52 weeks for the years ended September 27, 2014, September 28, 2013 and September 29, 2012.
	Operating Cycle: Consistent with industry practice, aerospace and defense related inventories, unbilled recoverable costs and profits on long-term contract receivables, customer advances and contract loss reserves include amounts relating to contracts having long production and procurement cycles, portions of which are not expected to be realized or settled within one year.
	Foreign Currency Translation: Assets and liabilities of subsidiaries that prepare financial statements in currencies other than the U.S. dollar are translated using rates of exchange as of the balance sheet date and the statements of earnings are translated at the average rates of exchange for each reporting period.
	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and assumptions.
	Revenue Recognition: We recognize revenue using either the percentage of completion method for contracts or as units are delivered or services are performed.
	Percentage of completion method for contracts: Revenue representing 34%, 33% and 32% of 2014, 2013 and 2012 sales, respectively, was accounted for using the percentage of completion, cost-to-cost method of accounting. This method of revenue recognition is predominantly used within the Aircraft Controls and Space and Defense Controls segments due to the contractual nature of the business activities, with the exception of their respective aftermarket activities. The contractual arrangements are either firm fixed-price or cost-plus contracts and are primarily with the U.S. Government or its prime subcontractors, foreign governments or commercial aircraft manufacturers, including Boeing and Airbus. The nature of the contractual arrangements includes customers’ requirements for delivery of hardware as well as funded nonrecurring development work in anticipation of follow-on production orders.
	Revenue on contracts using the percentage of completion, cost-to-cost method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total estimated contract revenue, less cumulative revenue recognized in prior periods. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for substantially all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations.
	Occasionally, it is appropriate to combine or segment contracts. Contracts are combined in those limited circumstances when they are negotiated as a package in the same economic environment with an overall profit margin objective and constitute, in essence, an agreement to do a single project. In such cases, revenue and costs are recognized over the performance period of the combined contracts as if they were one. Contracts are segmented in limited circumstances if the customer had the right to accept separate elements of the contract and the total amount of the proposals on the separate components approximated the amount of the proposal on the entire project. For segmented contracts, revenue and costs are recognized as if they were separate contracts over the performance periods of the individual elements or phases.
	Contract costs include only allocable, allowable and reasonable costs, as determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards for applicable U.S. Government contracts, and are included in cost of sales when incurred. The nature of these costs includes development engineering costs and product manufacturing costs including direct material, direct labor, other direct costs and indirect overhead costs. Contract profit is recorded as a result of the revenue recognized less costs incurred in any reporting period. Amounts representing performance incentives, penalties, contract claims or change orders are considered in estimating revenues, costs and profits when they can be reliably estimated and realization is considered probable. Revenue recognized on contracts for unresolved claims or unapproved contract change orders was not material for 2014, 2013 or 2012.
	For contracts with anticipated losses at completion, a provision for the entire amount of the estimated remaining loss is charged against income in the period in which the loss becomes known. Contract losses are determined considering all direct and indirect contract costs, exclusive of any selling, general or administrative cost allocations that are treated as period expenses. Loss reserves are more common on firm fixed-price contracts that involve, to varying degrees, the design and development of new and unique controls or control systems to meet the customers’ specifications.
	As units are delivered or services are performed: In 2014, 66% of our sales were recognized as units were delivered or as service obligations were satisfied. Revenue is recognized when the risks and rewards of ownership and title to the product are transferred to the customer. When engineering or similar services are performed, revenue is recognized upon completion of the obligation including any delivery of engineering drawings or technical data. This method of revenue recognition is predominantly used within the Industrial Systems, Components and Medical Devices segments, as well as with aftermarket activity. Profits are recorded as costs are relieved from inventory and charged to cost of sales and as revenue is recognized. Inventory costs include all product manufacturing costs such as direct material, direct labor, other direct costs and indirect overhead cost allocations.
	Shipping and Handling Costs: Shipping and handling costs are included in cost of sales.
	Research and Development: Research and development costs are expensed as incurred and include salaries, benefits, consulting, material costs and depreciation.
	Bid and Proposal Costs: Bid and proposal costs are expensed as incurred and classified as selling, general and administrative expenses.
	Equity-Based Compensation: Equity-based compensation expense is included in selling, general and administrative expenses.
	Earnings Per Share: Basic and diluted weighted-average shares outstanding are as follows:
		2014			2013			2012
	Basic weighted-average shares outstanding	44,362,412			45,335,336			45,246,960
	Dilutive effect of equity-based awards	590,025			488,384			471,364
	Diluted weighted-average shares outstanding	44,952,437			45,823,720			45,718,324
	Cash and Cash Equivalents: All highly liquid investments with an original maturity of three months or less are considered cash equivalents.
	Allowance for Doubtful Accounts: The allowance for doubtful accounts is based on our assessment of the collectibility of customer accounts. The allowance is determined by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.
	Inventories: Inventories are stated at the lower-of-cost-or-market with cost determined on the first-in, first-out (FIFO) method of valuation.
	Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated principally using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 15 years for building improvements, 12 years for furniture and fixtures, 10 years for machinery and equipment, 8 years for tooling and test equipment and 3 to 5 years for computer hardware and software. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the asset, whichever is shorter.
	Goodwill: We test goodwill for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that indicate that the fair value of a reporting unit is likely to be below its carrying amount.
	We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or selected reporting units. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test instead of a qualitative test for any or all of our reporting units.
	Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. We use the discounted cash flow method to estimate the fair value of our reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating margins and cash flows, the terminal growth rate and the weighted-average cost of capital. If the carrying value of the reporting unit exceeds its fair value, goodwill is considered impaired and any loss must be measured. To determine the amount of the impairment loss, the implied fair value of goodwill is determined by assigning a fair value to all of the reporting unit's assets and liabilities, including any unrecognized intangible assets, as if the reporting unit had been acquired in a business combination at fair value. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss would be recognized in an amount equal to that excess.
	We recorded a $38,200 goodwill impairment charge in 2013 in our Medical Devices reporting unit. There were no impairment charges recorded in 2014 or 2012.
	Acquired Intangible Assets: Acquired identifiable intangible assets are recorded at cost and are amortized over their estimated useful lives.
	Impairment of Long-Lived Assets: Long-lived assets, including acquired identifiable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. We use undiscounted cash flows to determine whether impairment exists and measure any impairment loss using discounted cash flows. In 2014, we recorded a $739 impairment charge in our Industrial Systems segment related to intangible assets from a product line we decided to exit. We also recorded a $1,296 impairment charge in our Medical Devices segment related to equipment from a product line we are no longer pursuing. Both of these charges are included as restructuring in the consolidated statements of earnings. There were no impairment charges recorded in 2013 or 2012.
	Product Warranties: In the ordinary course of business, we warrant our products against defect in design, materials and workmanship typically over periods ranging from twelve to sixty months. We determine warranty reserves needed by product line based on historical experience and current facts and circumstances. Activity in the warranty accrual is summarized as follows:
		2014				2013			2012
	Warranty accrual at beginning of year	$	17,429			$	18,859		$	19,247
	Additions from acquisitions	—				—			233
	Warranties issued during current year	12,611				9,019			9,842
	Adjustments to pre-existing warranties	(2,037		)		(1,911		)	(460		)
	Reductions for settling warranties	(7,759		)		(8,507		)	(10,016		)
	Foreign currency translation	(291		)		(31		)	13
	Warranty accrual at end of year	$	19,953			$	17,429		$	18,859
	Financial Instruments: Our financial instruments consist primarily of cash and cash equivalents, receivables, notes payable, accounts payable, long-term debt, interest rate swaps and foreign currency forwards. The carrying values for our financial instruments approximate fair value with the exception at times of long-term debt. We do not hold or issue financial instruments for trading purposes.
	We carry derivative instruments on the consolidated balance sheets at fair value, determined by reference to quoted market prices. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. Our use of derivative instruments is generally limited to cash flow hedges of certain interest rate risks and minimizing foreign currency exposure on foreign currency transactions, which are typically designated in hedging relationships, and intercompany balances, which are not designated as hedging instruments. Cash flows resulting from forward contracts are accounted for as hedges of identifiable transactions or events and classified in the same category as the cash flows from the items being hedged.
	Reclassifications: Certain prior year amounts have been reclassified to conform to the current year's presentation. The Consolidated Statements of Cash Flows has been restated to segregate income taxes from accrued expenses.

	Acquisitions and Divestitures
	All of our acquisitions are accounted for under the purchase method and, accordingly, the operating results for the acquired companies are included in the consolidated statements of earnings from the respective dates of acquisition. Under purchase accounting, we record assets and liabilities at fair value and such amounts are reflected in the respective captions on the consolidated balance sheets.
	There were no acquisitions completed in 2014.
	In 2013, we completed two business combinations. One of these business combinations was in our Space and Defense Controls segment. We acquired Broad Reach Engineering for $34,550 of cash consideration, issuance of $8,450 of notes payable and contingent consideration with an initial fair value of $3,447. Based in Colorado, Broad Reach Engineering is a leading designer and manufacturer of spaceflight electronics and software for aerospace, scientific, commercial and military missions. The company also provides ground testing, launch and on-orbit operations. We also completed one business combination in our Components segment. We acquired Aspen Motion Technologies, located in Radford, Virginia for $33,911 in cash. Aspen is a designer and manufacturer of high-performance permanent magnet brushless DC motors, integrated digital controls and motorized impellers. Aspen also specializes in custom motor designs for end product integration and significant product enhancement in a variety of high-performance industrial applications.
	In 2013, we completed one divestiture in our Medical Devices segment. We sold our Buffalo, New York operations of Ethox Medical for $5,000 in cash, plus a $200 note receivable.
	The purchase price allocations for the 2013 acquisitions are complete.

	Receivables	$	780,874		$	811,376
	Under our trade receivables securitization facility (the "Securitization Program"), we securitize certain trade receivables in transactions that are accounted for as secured borrowings. We maintain a subordinated interest in a portion of the pool of trade receivables that are securitized. The retained interest, which is included in receivables in the consolidated balance sheets, is recorded at fair value, which approximates the total amount of the designated pool of accounts receivable. See Note 7, Indebtedness, for additional disclosures related to the Securitization Program.
	Long-term contract receivables are primarily associated with prime contractors and subcontractors in connection with U.S. Government contracts, commercial aircraft and satellite manufacturers. Amounts billed under long-term contracts to the U.S. Government were $16,929 at September 27, 2014 and $11,532 at September 28, 2013. Unbilled recoverable costs and accrued profits under long-term contracts to be billed to the U.S. Government were $15,816 at September 27, 2014 and $11,963 at September 28, 2013. Unbilled recoverable costs and accrued profits principally represent revenues recognized on contracts that were not billable on the balance sheet date. These amounts will be billed in accordance with contract terms, generally as certain milestones are reached or upon shipment. Approximately 75% of unbilled amounts are expected to be collected within one year. In situations where billings exceed revenues recognized, the excess is included in customer advances.
	There are no material amounts of claims or unapproved change orders included in the consolidated balance sheets. There are no material balances billed but not paid by customers under retainage provisions.
	Concentrations of credit risk on receivables are limited to those from significant customers who are believed to be financially sound. Receivables from Boeing were $147,421 at September 27, 2014 and $182,050 at
	September 28, 2013. We perform periodic credit evaluations of our customers’ financial condition and generally do not require collateral.

	We recorded a $38,200 goodwill impairment in 2013 in our Medical Devices reporting unit. We test goodwill for impairment at least annually, during our fourth quarter. We estimated the fair value of this reporting unit using a discounted cash flow analysis, and our result was supported by information obtained as part of our strategic review of this business. In the fourth quarter of 2013, we began a strategic assessment of our Medical Devices segment. We determined that the medical pumps business is not core to our overall strategy, but we are currently operating the business as part of ongoing operations.

	The Securitization Program matures on February 13, 2015 and effectively increases our borrowing capacity by up to $100,000. Under the Securitization Program, we sell certain trade receivables and related rights to an affiliate, which in turn sells an undivided variable percentage ownership interest in the trade receivables to a financial institution, while maintaining a subordinated interest in a portion of the pool of trade receivables. The Securitization Program can be extended by agreement of the parties thereto for successive 364-day terms. Interest for the Securitization Program is 0.8% at September 27, 2014 and is based on prevailing market rates for short-term commercial paper plus an applicable margin. A commitment fee is also charged based on a percentage of the unused amounts available and is not material. The agreement governing the Securitization Program contains restrictions and covenants which include limitations on the making of certain restricted payments, creation of certain liens, and certain corporate acts such as mergers, consolidations and sale of substantially all assets. The Securitization Program has a minimum borrowing requirement equal to the lesser of either 80% of our borrowing capacity or 100% of our borrowing base, which is a subset of the trade receivables sold under this agreement. As of September 27, 2014, our minimum borrowing requirement is $80,000.
	In addition to the Securitization Program, we maintain short-term credit facilities with banks throughout the world that are principally demand lines subject to revision by the banks. Interest on outstanding lines of credit is 1.4% at September 27, 2014.

	On May 22, 2014, we amended our U.S. revolving credit facility. The amendment increased the capacity on our revolving credit facility from $900,000 to $1,100,000 and extended the maturity of the credit facility to May 22, 2019. The amendment also provides an expansion option, which permits us to request an increase to the credit facility of up to $200,000 upon satisfaction of certain conditions. The credit facility is secured by substantially all of our U.S. assets. The loan agreement contains various covenants which, among others, specify interest coverage and maximum leverage and capital expenditures. We are in compliance with all covenants. Interest on all of the outstanding credit facility borrowings is 1.5% and is based on LIBOR plus the applicable margin, which was
	138 basis points at September 27, 2014.
	Other long-term debt at September 27, 2014 consists of debt instruments being repaid in 2015 that carry an interest rate of 3.3%.
	On December 19, 2013, we repurchased our 7¼% senior subordinated notes due on January 15, 2018 at 103.625%, pursuant to an early redemption right. We redeemed the aggregate principal amount of $200,000 using proceeds drawn from our U.S. revolving credit facility. The associated loss on the redemption includes $6,945 of call premium paid to external bondholders and a $1,057 write off of deferred debt issuance costs.
	Maturities of long-term debt are $5,262 in 2015, $38 in 2016, $37 in 2017, $27 in 2018 and $765,012 in 2019.
	At September 27, 2014, we had pledged assets with a net book value of $1,573,599 as security for long-term debt.
	At September 27, 2014, we had $333,806 of unused short and long-term borrowing capacity, including $320,665 from the U.S. revolving credit facility. Commitment fees are charged on some of these arrangements and on the U.S. revolving credit facility based on a percentage of the unused amounts available and are not material.

Derivative Instruments and Hedges, Assets [Abstract]	'
Derivative Financial Instruments	'
	Derivative Financial Instruments
	We principally use derivative financial instruments to manage interest rate risk associated with long-term debt and foreign exchange risk related to foreign operations and foreign currency transactions. We enter into derivative financial instruments with a number of major financial institutions to minimize counterparty credit risk.
	Derivatives designated as hedging instruments
	Interest rate swaps are used to adjust the proportion of total debt that is subject to variable and fixed interest rates. The interest rate swaps are designated as hedges of the amount of future cash flows related to interest payments on variable-rate debt that, in combination with the interest payments on the debt, convert a portion of the variable-rate debt to fixed-rate debt. At September 27, 2014, we had interest rate swaps with notional amounts totaling $320,000. The interest rate swaps effectively convert this amount of variable-rate debt to fixed-rate debt at 2.0%, including the applicable margin of 138 basis points as of September 27, 2014. The interest will revert back to variable rates based on LIBOR plus the applicable margin upon the maturity of the interest rate swaps. These interest rate swaps mature at various times between January 15, 2015 and June 5, 2017.
	We use foreign currency forward contracts as cash flow hedges to effectively fix the exchange rates on future payments and revenue. To mitigate exposure in movements between various currencies, primarily the Philippine peso, we had outstanding foreign currency forwards with notional amounts of $43,548 at September 27, 2014. These contracts mature at various times through May 27, 2016.
	These interest rate swaps and foreign currency forwards are recorded on the consolidated balance sheet at fair value and the related gains or losses are deferred in shareholders’ equity as a component of Accumulated Other Comprehensive Income (Loss) (AOCI). These deferred gains and losses are reclassified into expense during the periods in which the related payments or receipts affect earnings. However, to the extent the interest rate swaps and foreign currency forwards are not perfectly effective in offsetting the change in the value of the payments being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was not material in 2014, 2013 or 2012.
	Derivatives not designated as hedging instruments
	We also have foreign currency exposure on balances, primarily intercompany, that are denominated in a foreign currency and are adjusted to current values using period-end exchange rates. The resulting gains or losses are recorded in the consolidated statements of earnings. To minimize foreign currency exposure, we have foreign currency forwards with notional amounts of $206,396 at September 27, 2014. The foreign currency forwards are recorded in the consolidated balance sheets at fair value and resulting gains or losses are recorded in the consolidated statements of earnings. We recorded net gains of $4,105 in 2014 and $2,249 in 2013 on the foreign currency forwards. These gains are included in other expense and generally offset the losses from the foreign currency adjustments on the intercompany balances that are also included in other income or expense.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Fair Value
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. The definition of the fair value hierarchy is as follows:
	Level 1 – Quoted prices in active markets for identical assets and liabilities.
	Level 2 – Observable inputs other than quoted prices in active markets for similar assets and liabilities.
	Level 3 – Inputs for which significant valuation assumptions are unobservable in a market and therefore value is based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require.
	Our derivatives are valued using various pricing models or discounted cash flow analyses that incorporate observable market data, such as interest rate yield curves and currency rates, and are classified as Level 2 within the valuation hierarchy. Our Level 3 fair value liabilities represent contingent consideration recorded for acquisitions to be paid if various financial targets are met. The amounts recorded were calculated for each payment scenario in each period using an estimate of the probability of the future cash outflows. The varying contingent payments were then discounted to the present value at the weighted average cost of capital. Fair value is assessed on a quarterly basis, or whenever events or circumstances change that indicate an adjustment is required. The assessment includes an evaluation of the performance of the acquired business compared to previous expectations, changes to future projections and the probability of achieving the earn out targets.
	The following table presents the fair values and classification of our financial assets and liabilities measured on a recurring basis as of September 27, 2014:
		Classification	Level 1			Level 2			Level 3		Total
	Interest rate swaps	Other current assets	$	—		$	70		—		$	70

	Restructuring
	In 2013, we initiated restructuring plans to better align our cost structure with projected sales levels. The restructuring actions taken have resulted in workforce reductions, primarily in the U.S., Europe and Asia.
	In 2014, we initiated restructuring plans in response to the business outlook, which includes a change in the mix of sales and delays and cancellations of orders for certain product lines. The restructuring actions taken will result in workforce reductions, primarily in the U.S. and Europe.
	Restructuring expense in 2014 principally relates to severance, but also includes $1,296 for the impairment of long-lived assets in our Medical Devices segment and $739 for the impairment of intangibles assets in our Industrial Systems segment. Restructuring activity for severance by segment is as follows:
		Aircraft Controls			Space and Defense Controls			Industrial Systems			Total

Employee Benefit Plans	'
	Employee Benefit Plans
	We maintain multiple employee benefit plans, covering employees at certain locations.
	Our qualified U.S. defined benefit pension plan is not open to new entrants. New employees are not eligible to participate in the pension plan. Instead, we make contributions for those employees to an employee-directed investment fund in the Moog Inc. Retirement Savings Plan ("RSP"). The Company’s contributions are based on a percentage of the employee’s eligible compensation and age. These contributions are in addition to the employer match on voluntary employee contributions.
	The RSP includes an Employee Stock Ownership Plan. As one of the investment alternatives, participants in the RSP can acquire our stock at market value. We match 25% of the first 2% of eligible compensation contributed to any investment selection. Shares are allocated and compensation expense is recognized as the employer share match is earned. At September 27, 2014, the participants in the RSP owned 552,011 Class A shares and 1,684,812 Class B shares.
	The changes in projected benefit obligations and plan assets and the funded status of the U.S. and non-U.S. defined benefit plans are as follows:

	of Class B common stock. Our funding policy is to contribute at least the amount required by law in the respective countries.
	The total accumulated benefit obligation as of the measurement date for all defined benefit pension plans was $877,846 in 2014 and $766,870 in 2013. At the measurement date in 2014, our plans had fair values of plan assets totaling $706,431. At the measurement date in 2014, three of our plans had fair values of plan assets totaling $78,643, which exceeded their accumulated benefit obligations of $67,423. At the measurement date in 2013, two of our plans had fair values of plan assets totaling $47,847, which exceeded their accumulated benefit obligations of $40,984. The following table provides aggregate information for the other pension plans, which have projected benefit obligations or accumulated benefit obligations in excess of plan assets:
			September 27,				28-Sep-13
			2014
	Projected benefit obligation		$	895,302			$	802,239
	Accumulated benefit obligation		810,424				725,886
	Fair value of plan assets		627,788				549,696
	Weighted-average assumptions used to determine benefit obligations as of the measurement dates and weighted-average assumptions used to determine net periodic benefit cost are as follows:
		U.S. Plans									Non-U.S. Plans
		2014			2013			2012			2014			2013			2012
	Assumptions for net periodic benefit cost:
	Discount rate	5	%		3.7	%		4.7	%		3.7	%		4	%		4.7	%
	Return on assets	8.4	%		8.6	%		8.9	%		4.1	%		4.5	%		5.5	%
	Rate of compensation increase	4.1	%		4.1	%		3.8	%		2.8	%		2.9	%		3	%
	Assumptions for benefit obligations:
	Discount rate	4.4	%		5	%		3.7	%		3.1	%		3.6	%		3.9	%
	Rate of compensation increase	4.1	%		4.1	%		4.1	%		2.7	%		2.8	%		2.9	%
	Pension plan investment policies and strategies are developed on a plan specific basis, which varies by country. At September 27, 2014, the U.S. plans represented 83% of consolidated pension assets, while the non-U.S. plans represented 17% of consolidated pension assets, the largest concentration being in the United Kingdom (6%). The overall objective for the long-term expected return on both domestic and international plan assets is to earn a rate of return over time to meet anticipated benefit payments in accordance with plan provisions. The long-term investment objective of both the domestic and international retirement plans is to maintain the economic value of plan assets and future contributions by producing positive rates of investment return after subtracting inflation, benefit payments and expenses. Each of the plan’s strategic asset allocations is based on this long-term perspective and short-term fluctuations are viewed with appropriate perspective.
	The U.S. qualified defined benefit plan’s assets are invested for long-term investment results. To accommodate the long-term investment horizon while providing appropriate liquidity, the plan maintains a liquid cash reserve of one-month to three-months of benefit distributions. Its assets are broadly diversified to help alleviate the risk of adverse returns in any one security or investment class. The international plans’ assets are invested in both low-risk and high-risk investments in order to achieve the long-term investment strategy objective. Investment risks for both domestic and international plans are considered within the context of the entire plan, rather than on a security-by-security basis.
	The U.S. qualified defined benefit plan and certain international plans have investment committees that are responsible for formulating investment policies, developing manager guidelines and objectives and approving and managing qualified advisors and investment managers. The guidelines established for each of the plans define permitted investments within each asset class and apply certain restrictions such as limits on concentrated holdings in order to meet overall investment objectives.
	Pension obligations and the related costs are determined using actuarial valuations that involve several assumptions. The return on assets assumption reflects the average rate of return expected on funds invested or to be invested to provide for the benefits included in the projected benefit obligation. In determining the return on assets assumption, we consider the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes and economic and other indicators of future performance. Asset management objectives include maintaining an adequate level of diversification to reduce interest rate and market risk and to provide adequate liquidity to meet immediate and future benefit payment requirements.
	In determining our U.S. pension expense for 2014, we assumed an average rate of return on U.S. pension assets of approximately 8.4% measured over a planning horizon with reasonable and acceptable levels of risk. The rate of return assumed an average of 60% in equity securities, 30% in fixed income securities and 10% in other securities. In determining our non-U.S. pension expense for 2014, we assumed an average rate of return on non-U.S. pension assets of approximately 4.1% measured over a planning horizon with reasonable and acceptable levels of risk. The rate of return assumed an average asset allocation of 40% in equity securities and 60% in fixed income securities.
	The weighted average asset allocations by asset category for the pension plans as of September 27, 2014 and September 28, 2013 are as follows:
		U.S. Plans								Non-U.S. Plans
		Target		2014			2013			Target		2014			2013
				Actual			Actual					Actual			Actual
Asset category:
Equity	45%-70%		54	%		60	%		40%-60%		30	%		30	%
Debt	20%-35%		34	%		30	%		40%-60%		41	%		43	%
Real estate and other	10%-20%		12	%		10	%		0%-30%		28	%		27	%

The valuation methodologies used for pension plan assets measured at fair value have not changed in the past two years. Cash and cash equivalents consist of direct cash holdings and institutional short-term investment vehicles. Direct cash holdings are valued at cost, which approximates fair value. Institutional short-term investment vehicles are valued daily. Investments in U.S. Government obligations are valued by a pricing service based upon closing market prices at year end. Shares of registered investment companies are valued at net asset value of shares held by the plan at year end. Common stocks traded on national exchanges are valued at the last reported sales price. Investments denominated in foreign currencies are translated into U.S. dollars using the last reported exchange rate. Fixed income funds are valued using methods, such as dealer quotes, available trade information, spreads, bids and offers provided by a pricing vendor. Investments in limited partnerships are valued based on the net asset value of our share in the fair value of the investments at year end. The limited partnerships have unfunded commitments of $20,743 at September 27, 2014. Common collective trust funds consist of pools of investments used by institutional investors to obtain exposure to equity and fixed income markets. Common collective trust funds held by us invest primarily in investment grade fixed income securities, common stock and real property assets. The common collective trusts have no unfunded commitments at September 27, 2014, and there are no significant restrictions on redemptions. Shares held in common collective trust funds are reported at the net unit value of units held by the trust at year end. The unit value is determined by the total value of fund assets divided by the total number of units of the fund owned. Investments in insurance contracts are valued at contract value, which is the fair value of the underlying investment of the insurance company. Securities or other assets for which market quotations are not readily available or for which market quotations do not represent the value at the time of pricing (including certain illiquid securities) are fair valued in accordance with procedures established under the supervision and responsibility of the Custodian of that investment.
Such procedures may include the use of independent pricing services or affiliated advisor pricing, which use prices based upon yields or prices of securities of comparable quality, coupon, maturity and type, indications as to values from dealers, operating data and general market conditions.
The preceding methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although we believe the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
Pension expense for all plans, including costs for various defined contribution plans, is as follows:
	U.S. Plans												Non-U.S. Plans
	2014				2013				2012				2014				2013			2012
Service cost	$	21,571			$	26,856			$	23,347			$	5,533			$	4,874		$	4,046

Total pension expense	$	41,279			$	53,169			$	37,310			$	14,829			$	14,290		$	11,996
The estimated net prior service cost and net actuarial loss that will be amortized from accumulated other comprehensive loss into net periodic benefit cost for pension plans in 2015 are $92 and $24,782, respectively.
Benefits expected to be paid to the participants of the plans are:
		U.S. Plans				Non-U.S. Plans
2015		$	24,970			$	5,830
2016		27,335				5,796
2017		30,149				5,998
2018		32,756				6,062
2019		35,500				6,670
Five years thereafter		227,600				39,578
We presently anticipate contributing approximately $52,500 to the U.S. plans and $9,000 to the non-U.S. plans in 2015.
We provide postretirement health care benefits to certain domestic retirees, who were hired prior to October 1, 1989. There are no plan assets. The transition obligation was being expensed over 20 years and was fully amortized in 2013. The changes in the accumulated benefit obligation of this unfunded plan for 2014 and 2013 are shown in the following table:
		September 27,				28-Sep-13
		2014
Change in Accumulated Postretirement Benefit Obligation (APBO):
APBO at prior year measurement date		$	14,370			$	17,456
Service cost		225				292
Interest cost		624				549
Contributions by plan participants		1,725				1,550
Benefits paid		(2,513		)		(2,617		)
Actuarial losses (gains)		900				(2,860		)

Actuarial gains		(2,303		)		(3,464		)
Amount recognized in accumulated other comprehensive loss, before taxes		$	(2,303	)		$	(3,464	)
The cost of the postretirement benefit plan is as follows:
		2014				2013				2012
Service cost		$	225			$	292			$	330
Interest cost		624				549				785
Amortization of transition obligation		—				361				394
Amortization of actuarial gain		(261		)		—				—
Net periodic postretirement benefit cost		$	588			$	1,202			$	1,509
As of the measurement date, the assumed discount rate used in the accounting for the postretirement benefit obligation was 3.9% in 2014, 4.5% in 2013 and 3.3% in 2012. As of the measurement date, the assumed discount rate used in the accounting for the net periodic postretirement benefit cost was 4.5% in 2014, 3.3% in 2013 and 4.5% in 2012.
For measurement purposes, a 7.2%, 6.7% and 7.5% annual per capita rate of increase of medical and drug costs before age 65, medical costs after age 65 and drug costs after age 65, respectively, were assumed for 2015, all gradually decreasing to 4.5% for 2028 and years thereafter. A one percentage point increase in this rate would increase our accumulated postretirement benefit obligation as of the measurement date in 2014 by $515, while a one percentage point decrease in this rate would decrease our accumulated postretirement benefit obligation by $480. There would be no material effect on the total service cost and interest cost components of the net periodic postretirement benefit cost given a one percentage point increase or decrease in this rate.
Employee and management profit sharing reflects a discretionary payment based on our financial performance. Profit share expense was $22,030, $14,950 and $25,100 in 2014, 2013 and 2012, respectively.

	At September 27, 2014, various subsidiaries had tax benefit carryforwards totaling $39,158. Much of these tax benefit carryforwards do not expire and can be used to reduce current taxes otherwise due on future earnings of those subsidiaries. The change in the valuation allowance relates to tax benefit carryforwards reflecting recent and projected financial performance, tax planning strategies and statutory tax carryforward periods.
	No provision has been made for U.S. federal or foreign taxes on that portion of certain foreign subsidiaries’ undistributed earnings ($776,664 at September 27, 2014) considered to be permanently reinvested. It is not practicable to determine the amount of tax that would be payable if these amounts were repatriated to the U.S.

We are subject to income taxes in the U.S. and in various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require the application of significant judgment. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2011. The statute of limitations in several jurisdictions will expire in the next twelve months and we have no unrecognized tax benefits to be recognized if the statute of limitations expires without the relevant taxing authority examining the applicable returns.
We record interest and penalties related to unrecognized tax benefits in income tax expense. We had accrued interest and penalties of $1,699 and $1,363 at September 27, 2014 and September 28, 2013, respectively. We expensed interest of $348 and $309 for 2014 and 2013, respectively.

Stockholders' Equity Note [Abstract]	'
Shareholders' Equity	'
	Shareholders’ Equity
	Class A and Class B common stock share equally in our earnings and are identical with certain exceptions. Other than on matters relating to the election of directors or as required by law where the holders of Class A and Class B shares vote as separate classes, Class A shares have limited voting rights, with each share of Class A being entitled to one-tenth of a vote on most matters, and each share of Class B being entitled to one vote. Class A shareholders are entitled, subject to certain limitations, to elect at least 25% of the Board of Directors (rounded up to the nearest whole number) with Class B shareholders entitled to elect the balance of the directors. No cash dividend may be paid on Class B shares unless at least an equal cash dividend is paid on Class A shares. Class B shares are convertible at any time into Class A shares on a one-for-one basis at the option of the shareholder. The number of common shares issued reflects conversion of Class B to Class A of 14,471 in 2014, 37,936 in 2013 and 40,549 in 2012.
	Class A shares reserved for issuance at September 27, 2014 are as follows:
		Shares
	Conversion of Class B to Class A shares	7,652,182
	2008 Stock Appreciation Rights Plan	3,395,028
	2003 Stock Option Plan	602,288
	Class A shares reserved for issuance	11,649,498
	We are authorized to issue up to 10,000,000 shares of preferred stock. The Board of Directors may authorize, without further shareholder action, the issuance of additional preferred stock which ranks senior to both classes of our common stock with respect to the payment of dividends and the distribution of assets on liquidation. The preferred stock, when issued, would have such designations relative to voting and conversion rights, preferences, privileges and limitations as determined by the Board of Directors.

Equity-Based Compensation	'
	Equity-Based Compensation
	We have equity-based compensation plans that authorize the issuance of equity-based awards for shares of Class A common stock to directors, officers and key employees. Equity-based compensation grants are designed to reward long-term contributions to Moog and provide incentives for recipients to remain with Moog.
	Equity-based compensation expense is based on share-based payment awards that are ultimately expected to vest. Vesting requirements vary for directors, officers and key employees. In general, options and stock appreciation rights (SARs) granted to outside directors vest one year from the date of grant, options granted to officers vest on various schedules, options granted to key employees vest in equal annual increments over a period of five years from the date of grant and SARs granted to officers and key employees vest in equal annual installments over a period of three years from the date of grant.
	The fair value of equity-based awards granted was estimated on the date of grant using the Black-Scholes option-pricing model. The following table provides the range of assumptions used to value equity-based awards and the weighted-average fair value of the awards granted.
		2014				2013				2012
	Expected volatility	29% - 39%				34% - 40%				40% - 42%
	Risk-free rate	.7% - 2.0%				.4% - 1.1%				.5% - 1.4%
	Expected dividends	—		%		—		%		—		%
	Expected term	3-7 years				3-7 years				3-7 years
	Weighted-average fair value of SARs granted	$	23.74			$	14.1			$	16.92
	To determine expected volatility, we generally use historical volatility based on weekly closing prices of our Class A common stock over periods that correlate with the expected terms of the awards granted. The risk-free rate is based on the United States Treasury yield curve at the time of grant for the appropriate term of the awards granted. Expected dividends are based on our history and expectation of dividend payouts. The expected term of equity-based awards is based on vesting schedules, expected exercise patterns and contractual terms.
	The 2008 Stock Appreciation Rights Plan (2008 Plan) authorizes the issuance of 4,000,000 SARs, which represent the right to receive shares of Class A common stock. The exercise price of the SARs, determined by a committee of the Board of Directors, may not be less than the fair market value of the Class A common stock on the grant date. The number of shares received upon exercise of a SAR is equal in value to the difference between the fair market value of the Class A common stock on the exercise date and the exercise price of the SAR. The term of a SAR may not exceed ten years from the grant date.
	The 2003 Stock Option Plan (2003 Plan) authorizes the issuance of options for 1,350,000 shares of Class A common stock. The 1998 Stock Option Plan (1998 Plan) authorizes the issuance of options for 2,025,000 shares of Class A common stock. Under the terms of the plans, options may be either incentive or non-qualified. Options outstanding as of September 27, 2014 consisted of both incentive options and non-qualified options. The exercise price, determined by a committee of the Board of Directors, may not be less than the fair market value of the Class A common stock on the grant date. Options become exercisable over periods not exceeding ten years.
	Options and SARs are as follows:

	Segments
	Aircraft Controls. We design, manufacture and integrate primary and secondary flight controls for military and commercial aircraft and provide aftermarket support. Our systems are used on both development and production programs in large commercial transports, supersonic fighters, multi-role military aircraft, business jets and rotorcraft. We also supply ground-based navigation aids.
	We are currently working on the KC-46 military air refueling tanker on the military side, and the Airbus A350XWB, COMAC C919, the Bell 525 Helicopter and the Embraer E-Jet E2 family on the commercial side. Typically development programs require concentrated periods of research and development by our engineering teams, while production programs are generally long-term manufacturing efforts that extend for as long as the aircraft builder receives new orders.
	In the past few years, a number of significant programs have begun to transition from the development phase to initial low-rate production, including the Lockheed Martin F-35 Joint Strike Fighter on the military side, and the Boeing 787, Gulfstream G650 and G280 on the commercial side. In terms of mature production programs, our large military programs include the F/A-18E/F Super Hornet, the V-22 Osprey tiltrotor and the Black Hawk UH-60/Seahawk SH-60 helicopter, while our large commercial production programs include the full line of Boeing 7-series aircraft, Airbus A330 and A380 and a variety of business jets.
	Aftermarket sales, which represented 32%, 32% and 34% of 2014, 2013 and 2012 sales, respectively, for this segment consist of the maintenance, repair, overhaul and parts supply for both military and commercial aircraft. Further, we sell spare parts and line replaceable units to both military and commercial customers that they store throughout the world in order to minimize down time.
	Space and Defense Controls. We provide controls for satellites, space vehicles, launch vehicles, armored combat vehicles, tactical and strategic missiles, security and surveillance and other defense applications.
	Within our space market, we design, manufacture and integrate commercial and military satellite positioning controls.

Other industrial automation markets we serve include material handling and paper and lumber mills.
	In the energy market, we supply solutions for power generation applications which allow for precise control and greater safety of fuel metering and guide vane positioning on steam and gas turbines. We also design and manufacture high reliability systems and components for applications in oil and gas exploration and production, including downhole drilling, topside and subsea environments, as well as electric pitch controls and blade monitoring systems for wind turbines.
	In the simulation and test market, we supply electromechanical motion simulation bases for the flight simulation and training markets, as well as medical training simulators. For the test markets, we supply custom test systems and controls for automotive, structural and fatigue testing.
	Components. Our Components segment serves many of the same markets as our other segments. Our Components segment’s three largest product categories are slip rings, fiber optic rotary joints and motors.
	Slip rings and fiber optic rotary joints use sliding contacts and optical technology to allow unimpeded rotation while delivering power and data through a rotating interface. They come in a range of sizes that allow them to be used in many applications, including diagnostic imaging CT scan medical equipment, blade de-icing and data transfer for rotorcraft, remotely operated vehicles and floating platforms for offshore oil exploration, surveillance cameras, forward-looking infrared camera installations and radar pedestals, satellites, missiles and wind turbines.
	Our motors are used in an equally broad range of markets, many of which are the same as for slip rings. We design and manufacture a series of fractional horsepower brushless motors that provide extremely low acoustic noise and reliable long life operation, with the largest market being sleep apnea equipment. Industrial customers use our motors for material handling and electric pumps. Military programs use our motors for gimbals, missiles and radar pedestals.
	Our Components’ segment's other product lines include electromechanical actuators for military, aerospace and commercial applications, fiber optic modems that provide electrical-to-optical conversion of communication and data signals, avionic instrumentation, subsea navigation and control systems, acoustic sensors and sonars for energy and marine applications including remotely-operated underwater vehicles, and optical switches and resolvers.
	Medical Devices. Our Medical Devices segment operates within four areas: infusion therapy, enteral clinical nutrition, sensors and surgical hand pieces.
	We manufacture and distribute a complete line of portable pumps, stationary pumps and disposable sets that are used in the delivery of enteral nutrition for patients in their own homes, hospitals and long-term care facilities.
	For infusion therapy, our primary products are electronic ambulatory infusion pumps along with the associated administration sets. Applications of these products include hydration, nutrition, patient-controlled analgesia, local anesthesia, chemotherapy and antibiotics.
	We manufacture and distribute ultrasonic and optical sensors used to detect air bubbles in infusion pump lines and ensure accurate fluid delivery. Our surgical hand pieces are used to safely fragment and aspirate tissue in common medical procedures such as cataract removal.

	Commitments and Contingencies
	From time to time, we are involved in legal proceedings. We are not a party to any pending legal proceedings which management believes will result in a material adverse effect on our financial condition, results of operations or cash flows.
	We are engaged in administrative proceedings with governmental agencies and legal proceedings with governmental agencies and other third parties in the normal course of our business, including litigation under Superfund laws, regarding environmental matters. We believe that adequate reserves have been established for our share of the estimated cost for all currently pending environmental administrative or legal proceedings and do not expect that these environmental matters will have a material adverse effect on our financial condition, results of operations or cash flows.
	In the ordinary course of business we could be subject to ongoing claims or disputes from our customers, the ultimate settlement of which could have a material adverse impact on our consolidated results of operations. While the receivables and any loss provisions recorded to date reflect management's best estimate of the projected costs to complete a given project, there is still significant effort required to complete the ultimate deliverable. Future variability in internal cost and as well as future profitability is dependent upon a number of factors including deliveries, performance and government budgetary pressures. The inability to achieve a satisfactory contractual solution, further unplanned delays, additional developmental cost growth or variations in any of the estimates used in the existing contract analysis could lead to further loss provisions. Additional losses could have a material adverse impact on our financial condition, results of operations or cash flows in the period in which the loss may be recognized.
	We lease certain facilities and equipment under operating lease arrangements. These arrangements may include fair market renewal or purchase options. Rent expense under operating leases amounted to $26,238 in 2014, $28,070 in 2013 and $26,518 in 2012. Future minimum rental payments required under non-cancellable operating leases are $21,886 in 2015, $19,167 in 2016, $14,803 in 2017, $11,977 in 2018, $9,716 in 2019 and $43,303 thereafter.
	We are contingently liable for $14,335 of standby letters of credit issued by a bank to third parties on our behalf at September 27, 2014. Purchase commitments outstanding at September 27, 2014 are $517,692, including $19,257 for property, plant and equipment.

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Sep. 27, 2014
Accounting Policies [Abstract]	'
Consolidation	'
	Consolidation: The consolidated financial statements include the accounts of Moog Inc. and all of our U.S. and foreign subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	'
	Fiscal Year: Our fiscal year ends on the Saturday that is closest to September 30. The consolidated financial statements include 52 weeks for the years ended September 27, 2014, September 28, 2013 and September 29, 2012.
Operating Cycle	'
	Operating Cycle: Consistent with industry practice, aerospace and defense related inventories, unbilled recoverable costs and profits on long-term contract receivables, customer advances and contract loss reserves include amounts relating to contracts having long production and procurement cycles, portions of which are not expected to be realized or settled within one year.
Foreign Currency Translation	'
	Foreign Currency Translation: Assets and liabilities of subsidiaries that prepare financial statements in currencies other than the U.S. dollar are translated using rates of exchange as of the balance sheet date and the statements of earnings are translated at the average rates of exchange for each reporting period.
Use Of Estimates	'
	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and assumptions.
Percentage of Completion Method for Contracts	'
	Percentage of completion method for contracts: Revenue representing 34%, 33% and 32% of 2014, 2013 and 2012 sales, respectively, was accounted for using the percentage of completion, cost-to-cost method of accounting. This method of revenue recognition is predominantly used within the Aircraft Controls and Space and Defense Controls segments due to the contractual nature of the business activities, with the exception of their respective aftermarket activities. The contractual arrangements are either firm fixed-price or cost-plus contracts and are primarily with the U.S. Government or its prime subcontractors, foreign governments or commercial aircraft manufacturers, including Boeing and Airbus. The nature of the contractual arrangements includes customers’ requirements for delivery of hardware as well as funded nonrecurring development work in anticipation of follow-on production orders.
	Revenue on contracts using the percentage of completion, cost-to-cost method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total estimated contract revenue, less cumulative revenue recognized in prior periods. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for substantially all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations.
	Occasionally, it is appropriate to combine or segment contracts. Contracts are combined in those limited circumstances when they are negotiated as a package in the same economic environment with an overall profit margin objective and constitute, in essence, an agreement to do a single project. In such cases, revenue and costs are recognized over the performance period of the combined contracts as if they were one. Contracts are segmented in limited circumstances if the customer had the right to accept separate elements of the contract and the total amount of the proposals on the separate components approximated the amount of the proposal on the entire project. For segmented contracts, revenue and costs are recognized as if they were separate contracts over the performance periods of the individual elements or phases.
	Contract costs include only allocable, allowable and reasonable costs, as determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards for applicable U.S. Government contracts, and are included in cost of sales when incurred. The nature of these costs includes development engineering costs and product manufacturing costs including direct material, direct labor, other direct costs and indirect overhead costs. Contract profit is recorded as a result of the revenue recognized less costs incurred in any reporting period. Amounts representing performance incentives, penalties, contract claims or change orders are considered in estimating revenues, costs and profits when they can be reliably estimated and realization is considered probable. Revenue recognized on contracts for unresolved claims or unapproved contract change orders was not material for 2014, 2013 or 2012.
	For contracts with anticipated losses at completion, a provision for the entire amount of the estimated remaining loss is charged against income in the period in which the loss becomes known. Contract losses are determined considering all direct and indirect contract costs, exclusive of any selling, general or administrative cost allocations that are treated as period expenses. Loss reserves are more common on firm fixed-price contracts that involve, to varying degrees, the design and development of new and unique controls or control systems to meet the customers’ specifications.
Revenue Recognition	'
	As units are delivered or services are performed: In 2014, 66% of our sales were recognized as units were delivered or as service obligations were satisfied. Revenue is recognized when the risks and rewards of ownership and title to the product are transferred to the customer. When engineering or similar services are performed, revenue is recognized upon completion of the obligation including any delivery of engineering drawings or technical data. This method of revenue recognition is predominantly used within the Industrial Systems, Components and Medical Devices segments, as well as with aftermarket activity. Profits are recorded as costs are relieved from inventory and charged to cost of sales and as revenue is recognized. Inventory costs include all product manufacturing costs such as direct material, direct labor, other direct costs and indirect overhead cost allocations.
	Revenue Recognition: We recognize revenue using either the percentage of completion method for contracts or as units are delivered or services are performed.
Shipping and Handling Cost	'
	Shipping and Handling Costs: Shipping and handling costs are included in cost of sales.
Research and Development	'
	Research and Development: Research and development costs are expensed as incurred and include salaries, benefits, consulting, material costs and depreciation.
Bid And Proposal Costs	'
	Bid and Proposal Costs: Bid and proposal costs are expensed as incurred and classified as selling, general and administrative expenses.
Equity-Based Compensation	'
	Equity-Based Compensation: Equity-based compensation expense is included in selling, general and administrative expenses.
Earnings Per Share	'
	Earnings Per Share: Basic and diluted weighted-average shares outstanding are as follows:
		2014			2013			2012
	Basic weighted-average shares outstanding	44,362,412			45,335,336			45,246,960
	Dilutive effect of equity-based awards	590,025			488,384			471,364
	Diluted weighted-average shares outstanding	44,952,437			45,823,720			45,718,324
Cash and Cash Equivalents	'
	Cash and Cash Equivalents: All highly liquid investments with an original maturity of three months or less are considered cash equivalents.
Allowance For Doubtful Accounts	'
	Allowance for Doubtful Accounts: The allowance for doubtful accounts is based on our assessment of the collectibility of customer accounts. The allowance is determined by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.
Inventories	'
	Inventories: Inventories are stated at the lower-of-cost-or-market with cost determined on the first-in, first-out (FIFO) method of valuation.
Property, Plant And Equipment	'
	Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated principally using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 15 years for building improvements, 12 years for furniture and fixtures, 10 years for machinery and equipment, 8 years for tooling and test equipment and 3 to 5 years for computer hardware and software. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the asset, whichever is shorter.
Goodwill	'
	Goodwill: We test goodwill for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that indicate that the fair value of a reporting unit is likely to be below its carrying amount.
	We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or selected reporting units. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test instead of a qualitative test for any or all of our reporting units.
	Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. We use the discounted cash flow method to estimate the fair value of our reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating margins and cash flows, the terminal growth rate and the weighted-average cost of capital. If the carrying value of the reporting unit exceeds its fair value, goodwill is considered impaired and any loss must be measured. To determine the amount of the impairment loss, the implied fair value of goodwill is determined by assigning a fair value to all of the reporting unit's assets and liabilities, including any unrecognized intangible assets, as if the reporting unit had been acquired in a business combination at fair value. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss would be recognized in an amount equal to that excess.
	We recorded a $38,200 goodwill impairment charge in 2013 in our Medical Devices reporting unit. There were no impairment charges recorded in 2014 or 2012.
Acquired Intangible Assets	'
	Acquired Intangible Assets: Acquired identifiable intangible assets are recorded at cost and are amortized over their estimated useful lives.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets: Long-lived assets, including acquired identifiable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. We use undiscounted cash flows to determine whether impairment exists and measure any impairment loss using discounted cash flows. In 2014, we recorded a $739 impairment charge in our Industrial Systems segment related to intangible assets from a product line we decided to exit. We also recorded a $1,296 impairment charge in our Medical Devices segment related to equipment from a product line we are no longer pursuing. Both of these charges are included as restructuring in the consolidated statements of earnings. There were no impairment charges recorded in 2013 or 2012.
Product Warranties	'
	Product Warranties: In the ordinary course of business, we warrant our products against defect in design, materials and workmanship typically over periods ranging from twelve to sixty months. We determine warranty reserves needed by product line based on historical experience and current facts and circumstances. Activity in the warranty accrual is summarized as follows:
		2014				2013			2012
	Warranty accrual at beginning of year	$	17,429			$	18,859		$	19,247
	Additions from acquisitions	—				—			233
	Warranties issued during current year	12,611				9,019			9,842
	Adjustments to pre-existing warranties	(2,037		)		(1,911		)	(460		)
	Reductions for settling warranties	(7,759		)		(8,507		)	(10,016		)
	Foreign currency translation	(291		)		(31		)	13
	Warranty accrual at end of year	$	19,953			$	17,429		$	18,859
Financial Instruments	'
	Financial Instruments: Our financial instruments consist primarily of cash and cash equivalents, receivables, notes payable, accounts payable, long-term debt, interest rate swaps and foreign currency forwards. The carrying values for our financial instruments approximate fair value with the exception at times of long-term debt. We do not hold or issue financial instruments for trading purposes.
	We carry derivative instruments on the consolidated balance sheets at fair value, determined by reference to quoted market prices. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. Our use of derivative instruments is generally limited to cash flow hedges of certain interest rate risks and minimizing foreign currency exposure on foreign currency transactions, which are typically designated in hedging relationships, and intercompany balances, which are not designated as hedging instruments. Cash flows resulting from forward contracts are accounted for as hedges of identifiable transactions or events and classified in the same category as the cash flows from the items being hedged.
Reclassification, Policy [Policy Text Block]	'
	Reclassifications: Certain prior year amounts have been reclassified to conform to the current year's presentation. The Consolidated Statements of Cash Flows has been restated to segregate income taxes from accrued expenses
