基于振动信号的数控铣床刀具破损诊断方法

A Diagnostic Method for Tool Breakage of NC Milling Machine Based on Vibration Signals

介绍了一种刀具失效的诊断方法.主要是通过传感器在线检测时域中的信号,用数理统计方法处理检测数据,得出刀具破损的阈值.实现刀具破损自动报警,避免事故发生.

In this paper,the author introduces a kind of diagnostic method for tool breakage.By testing the on-line signals of sensor in time domain,the threshold value of tool breakage can be calculated by means of dealing with testing data with mathematical statistics.Therefore,the automatic alarm of tool breakage can be realized so as to prevent accidents.
