Abstract: In order to understand the grinding mechanism and analyze the grinding operation, it is necessary to study the contact phenomena between wheel and workpiece during grinding operation. The contact length, the grinding temperature distribution within the contact zone, and the grinding forces are measured in-process by using Critical Contact State mode, thermocouple method, and 3-axis piezoelectric dynamometer, respectively. It is found that the grinding conditions and the properties of work material have effects on the contact length, moreover, the mechanism of which is discussed in this paper. The results show that the contact length significantly interacts with grinding force and grinding temperature in the grinding zone.
