The Development of High Accuracy Turning Multiple Measurement and Control System

This paper introduces a new high accuracy turning Multiple measurement and control high accuracy turning Multiple measurement and control system developed by authors recently. It mainly consists of microcomputer, multichannel capactive probes, precision positioning and measurement equipment, (compensation micro-servo device) and high accuracy optical digital length gauge. The functions of the system include: on- line measurement of inside and outside diameter, length, and feed control of the turning tool. Positional accuracy of 0.03 μm, feed resolution of 0.1μ and feed accuracy of 0.5 μm are achieved.
