摘要：
A numerically controlled internal grinding machine for grinding a workpiece by a rough grinding operation with a rough grinding wheel and a finish grinding operation with a finish grinding wheel. The grinding machine detects the load power of a motor which drives the finish grinding wheel in order to determine a compensation value to enable subsequent compensation due to wear of the rough grinding wheel. In the successive rough grinding operation, the relative position of the workpiece is compensated for according to the determined compensation value, so that the diameter of the workpiece after the rough grinding operation is maintained at a desired constant value regardless of the wear of the rough grinding wheel.
