摘要: 本文提出一种新的切削状态实时监测的信号处理方法——频段能量法,它能有效地提取切削状态的信号特征,解决传统数字式谱分析中精度与实时性之间的矛盾,具有迅速、准确、抗干扰、易设定相对阈值和适应面广等优点。所建立的微机监测系统已初步实现了对刀具磨损阶段、刀具破损和切削颤振的实时监测。

Abstract: A new kind of signal processing approach for real time monitoring of cutting states, the frequency band-energy method, is proposed in this paper. By use of this method, the signal characteristics of cutting states can be effectively extracted and the contradiction between the accuracy and real time nature in conventional spectrum analysis can be solved. Therefore it possesses the advantages of rapidity, accuracy, interference-free, easy to set relative threshold and wide suitability. The real time monitoring of tool wear stage, tool breakage and cutting chatter is initially realized in the microcomputer based monitoring system.
