ABSTRACT:
An apparatus capable of automatically determining grinding wheel dressing timing for dressing a grinding wheel. The apparatus estimates the abrasion of the grinding wheel in a grinding cycle on the basis of machining data and grinding conditions, and divides the grinding cycle into a plurality of stages according to the estimated abrasion to carry out grinding wheel dressing after the completion of every stage of the grinding cycle. In grinding a workpiece having a plurality of ground sections, the abrasion of the grinding wheel in grinding each ground section is estimated, and the abrasion is accumulated in accordance with grinding sequence. A ground section after grinding which grinding wheel dressing is to be carried out is determined on the basis of the cumulative abrasion. Similarly, the abrasions are accumulated for each of workpieces. A grinding wheel dressing is carried out after the completion of grinding a workpiece so that the cumulative abrasion may not exceed a predetermined value.
