摘　　要：为有效地实时在线监测刀具的磨损状态,提出了基于声音识别技术的刀具磨损监测方法,进行了基于切削声信号HMM的刀具磨损程度的分级识别,监测系统能够对刀具的五级磨损划分进行准确识别,这为刀具的磨损监测提供了一条切实可行的途径。In order to monitor tool wear degree real time online effectively, a new tool-wear monitor method is based on the sound recognition technology, the tool-wear classification recognition based on the sound signal HMM is carried out. The monitor system can truly recognize the tool wear degree decomposed five wear levels, which provides an effective approach for tool-wear monitor.
