Production Control of Acceleration Sensing Devices -- CAM Related.

摘要

Current production control of acceleration sensing devices consists, essentially, of functional testing of the completed assemblies. To eliminate the excessive rework and scrap which is common to this system of control, the possibility was explored of assuring quality in the end item by controlling the quality of the components during manufacture. Current literature was searched for process control techniques applicable to the spring mass systems used in acceleration sensing devices. A concept was subsequently developed which would significantly improve the quality and uniformity of these systems through the use of computer-aided manufacturing techniques. Minicomputers and other recently developed manufacturing equipment, such as on-machine gages, stress-relieving equipment, separators and electronic load testers, were determined to be effective in controlling spring parameters and assuring uniform production. For fuzes which do not require the tight control provided by the minicomputer, the use of a spring separator in combination with an electronic load tester was found to provide a fully automated operation for a minimal investment.
