摘要
本文在已有的研究基础上通过对 4 5号钢和不锈钢的变切深切削实验 ,用高灵敏度的压电式振动加速度传感器对切削过程及其突变信号进行检测 ,并对非线性切削过程振动和信号特征提取进行了初步研究。结果表明 ,金属切削过程的突变主要是使被测信号的低频成分增加 ,用RMS、FC、RVF、RMSF。
Based on available research results this paper gave a discussion on experiments conducted upon medium carbon steel 45 and stainless steel, applying highly sensitive vibratory accelerated sensors to detect the cutting process and catastrophic signal, carrying out basic research in the vibration of nonlinear cutting process and the picking up of signals. The result shows that catastrophe of the process of metal cutting tends mostly to increase the component of low frequency of detected signal. Schemes RMS, FC, RVF, RMSF and KK can be used as target of detection and diagnosis of the phenomena of catastrophe.
