Aa. Houshmand et al., A DYNAMIC-MODEL FOR TOOL WEAR DETECTION USING ACOUSTIC-EMISSION, Mechanical systems and signal processing, 9(4), 1995, pp. 415-428
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
