Abstract

PURPOSE:To facilitate provision of a specified cut amount, by a method wherein movement of a tool is controlled so that a tool cuts or separates from a workpiece so as to adjust the current value of a tool driving motor to a set value. CONSTITUTION:The drive current value of a grinding stone rotating motor 24 is detected by a detecting circuit 26, and is compared with a target current value preset in a computing processing device 38 of a numerical control unit 30. According to a difference therebetween, movement of a rotary grinding stone 12 is controlled so that the rotary grinding stone is caused to cut and separate in the direction of the radius of a rolling roll 2 at a given speed. The drive current value of the motor 24 is set to a target current value, and by keeping a cut amount of a rotary grinding stone 12 at a specified value, the rolling roll 2 is ground to a given size.
