This study deals with the optimization of ceramics grinding operation with metal bonded diamond wheels.In this paper, the discrimination of the quality of wheel conditioning and of dressing interval is discussed based on signals obtained from an accelerometer pickup mounted on the spindle head of the surface grinder. As a result, it is clarified to identify whether truing and dressing operations are completed or not, by detecting the specific frequencies which are equivalent to the integral multiple numbers of spindle revolution and the principal characteristic frequency of the spindle head, respectively. Also, with 800Hz which is the characteristic frequency of the spindle head, as the specific frequency, it will be possible to determine the dressing interval by considering the rapid increase of acceleration amplitude.
