刀具磨损的研究方法很多，本文针对近些年发展的声发射技术( AE) 在监测刀具磨损上的应用，采用理论分析和现场试验的方法进行可行性分析和验证，结果表明: 在考察的几个影响声发射信号强度的因素之中，刀具主切削刃后刀面磨损量对其影响最为显著-Tool wear a lot of research methods, this paper developed in recent years for the acoustic emission technique (AE) monitoring tool wear on the application, using theoretical analysis and field test the feasibility of the method of analysis and verification, the results showed that: in the study of several among affecting acoustic emission signal intensity factor, flank wear their most significant impact on the main cutting edge tool
