Abstract
In a grinding machine, a grinding wheel is digitally fed toward a workpiece being supported by a rest apparatus. Means is provided to measure a diametral dimension of the workpiece during a grinding operation. A taper amount of the workpiece ground under the support of the rest apparatus being positioned at its advanced position is calculated at the time when the measuring means generates a signal for finishing a grinding operation on the workpiece. An advanced position of the rest apparatus is compensated for a next grinding operation in response to the calculated taper amount.
