PRODUCTION ENGINEERING MEASURE CR-(XM-45)/U CRYSTAL UNITS.
Abstract
The report covers Step I of the PEM study. It outlines the original objectives; discusses the design problems; traces the progress of the development; presents the specification finally derived; gives details of the designs established; includes a process manual to describe manufacturing operations and a quality control system for controlling and monitoring production; finally, it lists production yields and summarizes performance-evaluation data from 300 pilot-run samples. The project was concluded satisfactorily: a cumulative yield of 58.5% was obtained during the pilot run. There were no significant differences between natural quartz units and cultured quartz units, either in yields or performances. Statistical evaluation indicated that at least 99% of the pilot-run units met all requirements; more than 90% had performance levels significantly better than required to satisfy the specification.
