Abstract: It has been found from experiments that during turning tool breakage, the variation of the vibration signal in time domain in lower frequency range is remarkable, however, in wider frequency range it is not so significant.In this paper, a method to monitor turning tool breakage by the use of the variation of the time domain signal in lower frequency range is proposed. It is verified that the turning tool breakage can be detected within 20 milliseconds by this method.

Key words: tool breakage, vibration, in-process monitoring, turning
