摘要

为了实现金刚石滚轮加工的数字化和智能化，实现对金刚石滚轮磨削过程的监测，采用声发射传感器对滚轮粘结剂的磨削过程进行监测。通过对声发射信号的时频域分析，发现声发射信号的能量、持续时间、环数和幅值随磨料切割深度的增加而增加。在不同切削深度下，刮划粘结剂的声发射信号在频域的最大值约为55kHz，且信号在30-60khz频段的能量比最大。可以认为，磨削过程中粘结剂去除的主要频率为30-60khz。

Study on acoustic emission signal of diamond grinding roller binder

To realize the digitalization and intellectualization of diamond roller processing and to monitor diamond roller grinding, an acoustic emission sensor is used to monitor the experiment of grinding to the roller binder. Through the time-frequency domain analysis of the Acoustic Emission(AE) signal, it is found that the energy, duration, ring count, and amplitude of the AE signal increase with the increase of abrasive cutting depth. Under different cutting depths, the maximum value of the AE signal in the frequency domain of the scratching binder is about 55kHz, and the energy ratio of the signal in the frequency band of 30-60khz is the largest. It can be considered that the main frequency of the removal of the binder during grinding is 30-60khz.
