Abstract
When the amount of a change in load current supplied to a grinder is not more than a predetermined threshold value, the amount of piercing into a workpiece by the grinder is controlled according to the load current. When the amount of a change in load current exceeds the predetermined threshold value, the grinding speed of the grinder is controlled according to the load current. When performing a plurality of operations with one robot, a position correction value calculated in one operation is utilized to correct a target position in another operation.
