Abstract

This paper offers a detailed introduction to a successful technical solution to system error removing in grinding operation by Geometrical Adaptive Control(GAC). The system is composed of a machine tool an in-process measuring instrument and an on-line measuring machine. Accuracy of the workpiece ground is to be judged by measuring machine sends signals to in-process measuring instrument or grinder in order to control the feeding amount of tool thus a close-loop control system for grinding operation is formed. All errors made by the system (because of temperature humidity air pressure vibration time drift)will be removed through calibration with standard workpiece (self-examination of the measuring machine). FOREWORD With the development of science and technology in recent years mechanical processing tends to adaptive control and flexible manufacturing systems precision machinery and precision instrument are directed to high accuracy and automation. In the late 70s micro electronics technology makes IC from the stage of large-scale to ultra-large-scale Resolution of digital display reaches 0. 1 . tm. positioning accuracy of test instrument reaches the level of submicro-meter. The accuracy speed and stability of on-line measurer and measuring machine directly influences machining accuracy and working efficiency of proceesing system being inspected. Ready-made close-loop control system of on-line measurement in grinding operation meets the requirement of machining circle (4 seconds) . Its accuracy reaches 0. 5 ii m or even higher. In large batch production. GAC has
