Abstract:In order to solve the problem of excessive tool wear and breakage despite the timing tool change，the theories about tool monitoring technology and its parameter calibration method are studied.The application and verification are carried out in engine machining.The results show that the application of tool monitoring technology based on motor current can detect tool wear and breakage accurately，improve the tool utilization rate，prevent the problems of batch unqualified work pieces，protect the spindle，fixture and so on.
Keywords:timing tool change；excessive tool wear and breakage；tool monitoring technology；tool utilization rate
