Abstract

The relationship between the grinding conditions and AE wave in constant-cut surface grinding was considered for the purpose of examining the cognitive technology of a situation of grinding. Grinding of fine-ceramics generally advances by a brittle fracture. This report was considered the processing model of constant-cut surface grinding based on the Vickers hardness test. And, the amplitude of AE was formulated based on two kinds of cracks generated from this processing model. It was predicted that the amplitude of AE wave and the chip coefficient are a correlation. Some grinding experiments were conducted in order to examine the validity of the calculation formula. As a result, although some problems remained, relationship between the grinding conditions and the amplitude of AE wave was clarified. From this result, the guideline which predicts the situation of grinding using the amplitude of AE wave was acquired.
