Notes:
Tool monitoring is an important factor to restrict the improvement of productionefficiency, machining quality and automation level. The monitoring of the tool wear and breakageconditions on YCM-V116B machining center was studied, and the acquired milling sound signalswere analyzed in detail. By means of the classical time-frequency analysis, it was discovered thatthe wear sound had its own characteristic frequency band, and the frequency component within thefrequency band would change according to the change of wear conditions. So that the frequencycomponent within the frequency band will be a good indicator to monitor the tool wear conditionsexcellently. On the other hand, the tool breakage sound is a random signal that a transient change inamplitude is produced probably when tool breaks. The tool breakage conditions can be detectedexactly by the advantages of wavelet decomposition techniques. The analysis implies that the soundgenerated during the machining process can be used to monitor tool conditions, which provides anew approach to the sound applications in tool monitoring domain
