Abstract
In this study, the grinding wheel rotational speed was measured in a grinding process to monitor the grinding force and two methods-the deceleration slope method and the speed difference square method-were proposed. To enable the automatic computation of these parameters and to eliminate differences in parameter calculation between individuals, the determination of monitoring parameters was standardized. From experimental result, the standardized speed difference square method in this study showed very strong correlation with the tangential grinding force, and was not affected by the surface properties of the grinding wheel.
