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.
