摘　　要：金属加工过程中,切削刀具的状态对于生产效率和表面加工质量有重要影响,因此刀具磨损在线监测具有重要意义。介绍了最近几年常用的刀具磨损在线监测方法,包括切削力、振动、声发射、温度、电流与功率信号,分析了每种信号的监测方法及其特点,并与实验结果进行了对比。提出了多传感器融合技术能有效避免单独使用一种检测手段的弊端。In the process of metal machining,the state of the cutting tool has great influence on the efficiency of production and surface quality,therefore,tool wear online monitoring is of great significance. The commonly used online tool wear monitoring methods in recent years were introduced,including cutting forces,vibrations,acoustic emission,temperature,current and power signal. The monitoring methods of each signal and its characteristics were analyzed and compared with the experimental results. It is proposed that multi-sensor synthesis technique can effectively avoid the shortcoming of the method of using one single test.
