A DYNAMIC-MODEL FOR TOOL WEAR DETECTION USING ACOUSTIC-EMISSION

In this paper we present a dynamic model that can be used for monitori ng those processes that gradually deteriorate from an acceptable condi tion (process in control) to an unacceptable condition (process out of control). Monitoring of a cutting tool for detection of wear is an ex ample of such a process, where a cutting tool is sharp until it become s worn. The model is tested, using the spectral components of acoustic emission signals generated in an earlier work, the results are very p romising. (C) 1995 Academic Press Limited
