Accounting Policies [Abstract]
Basis of Presentation	The accompanying financial statements include the accounts of MTI and its consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America consistent in all material respects with those applied in our Annual Report on Form 10-K for the year ended August 28, 2014. In the opinion of our management, the accompanying unaudited consolidated financial statements contain all necessary adjustments, consisting of a normal recurring nature, to fairly state the financial information set forth herein.
Reclassifications	Certain reclassifications have been made to prior period amounts to conform to current period presentation. In addition, amounts for certain equipment purchases were reclassified from financing to investing within the statement of cash flows to better reflect the current nature of these transactions and to improve comparability with our industry peers.
Fiscal Period	Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Fiscal year 2015 contains 53 weeks and the third quarter and first nine months of 2015, which ended on June 4, 2015, contained 13 weeks and 40 weeks, respectively. Fiscal year 2014 contained 52 weeks and the third quarter and first nine months of 2014, which ended on May 29, 2014, contained 13 weeks and 39 weeks, respectively. All period references are to our fiscal periods unless otherwise indicated. These interim financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended August 28, 2014.

Disclosure of accounting policy for determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
