STUDY ON DETECTION OF CHATTER FOR MILLING BASED ON CURRENT SIGNAL

Abstract

Abstract: A dynamic model of chatter with two degree of freedom for milling process is presented, and the mechanism of chatter is analyzised. On the basis of these, the model of detecting the chatter based on current signal is given, which uses the ratio of high frequent and low frequent of current signal of spindle. The method which can detects the chatter reliably eliminates the effect of changes of manufacturing conditions on the results of detection. Besides these, the arithmetic is simple, and it is carried out real – time for its small time of calculating.

Key words: Chatter, Current signal, Detection, Milling
