The acoustic emission (AE) sensor has been widely used for monitoring the machining states or tool abrasion, etc. This paper presents the relation between machining time and states such as tool abrasion for ceramic machining processes, which can be applicable to develop the dentistry machining center. A commercial PZT-type of AE sensor was used for experiments, and the aquisition data was analyzed in the AE signal strength versus machining time. The results show that it is possible to estimate the tool life and the ceramic machining state. In the future, additional experiments for various machining conditions such as depth of cut and feed rate are strongly necessary so as to design an effective monitoring system for the ceramic machining processes through detecting the AE signal.
