Abstract: The surface roughness of workpiece in the process of ceramic grinding is affected by many factors. An online monitoring system for grinding roughness is proposed in this paper. This system monitors the AE signals that emerged in grinding to automatically identify wheel state and its parameters, wheel and workpiece speed, which inturn is used to control the workpiece roughness. We demonstrate the proposed system for internal grinding of ceramic work-piece with complex generatrix, and the results of experiments shows that the roughness is efficiently controlled.
