concepts and 5 adopted SPC during 1-8; these actions were significantly influenced by gear producers' customers. Most firms have only begun to adopt TQC since 1. Other management techniques that companies stated they had adopted were group technology centers, total quality management (TQM), Statistical Quality Control (SQC), continuous improvement, and simultaneous engineering. 1 The adoption of such techniques has led to significant increases in productivity. Data from the Commission' questionnaire indicate that work-in-process turnover rates have increased, defect rates have decreased, lead times have been reduced, and machine setup times have also been reduced by using these techniques. In many 1 Ford announced that it would use simultaneous engineering for the computerized production testing equipment for its CD4E transmissions to be produced in the early 1s. See Al Wrigley, *Ford, GM Shift Into Drive on New Transmission Plans," Metalworking News, May 8, 1, pp. 1, 3. instances, turnovers of work-in-progress have doubled, resulting in products being produced faster with less inventory on the factory floor. Defect rates have fallen by as much as 9 percent and lead times have been cut in half. In other instances, although defect rates or lead times did not change significantly, machine set-up time was reduced significantly, saving the company hours of production time. Use and Cost of Materials The raw materials and components used to produce gears and gearing include variety of steel castings, forgings, and bar stock, as well as bronze castings and bearings. Other miscellaneous components include seals and lubricating oils. Data from the Commission' questionnaires shown in table 4-7 report the share of total delivered cost of certain materials used by .. gear producers in 1, as well as the average share of the delivered cost of materials accounted for by imports. .. producers use more gear blanks made of castings than
