Monitoring system for cutting tool failure using acoustic emission sensor.

Failure of a cutting tool is one of the largest troubles in the automated machining system. Therefore several methods have been proposed, so far to detect the cutting tool failure. However, most of them, have some problems from the viewpoint of the practical application. In this study, an acoustic emission sensor is used to detect the cutting tool failure, and a monitoring system which has high reliability is proposed. Failures of the single-point as well as multipoint cutting tool are successfully detected with the monitoring system developed in this study.
