ABSTRACT:
Wear on the dressing tool is derived from an amount of movement that a grinding wheel is advanced until issuance of a signal from a sizing device for correcting data on the radius of the grinding wheel. The data on the radius of the grinding wheel is thus indicative of an actual radius of the grinding wheel regardless of a variation in the grinding wheel radius due to the wear of a dressing tool. Accordingly, the grinding surface of the grinding wheel can be exactly positioned at a grinding start position after the grinding wheel has been returned to its original position upon power supply failure, emergency machine shutdown or the like, so that any unwanted interference between the grinding wheel and a workpiece can be avoided.
