摘要：

Dimentional inaccuracies are one of the major problems during the turning of a long bar. This is explained by the fact that flank wear on the tool cause a a tapering effect. This paper describes the design and testing of a pneumatic feedback system that can be mounted on a centre lathe to improve the dimensional stability during turning by on-line tool wear sensing and compensation. The proposed system consists of a pneumatic sensor to sense the tool wear during machining, a pilot-controlled direction control valve to amplify the signal obtained from the pneumatic sensor and an actuating mechanism to move the tool for compensation of dimensional in accuracies. The proposed sysmtem is tested for various cutting conditions. The improvement in the dimensional accuracy is shown by taking a cut with pneumatic feedback system and the repeating the cut with identical cutting conditions but without feedback. The experimental results show that the use of the proposed feedback system results inproved dimentional accuracy. © 1990.
