Abstract
PURPOSE:To automatically and easily correct a decrease in a grinding amount due to resilient deformation of a workpiece occurring during machining, by a method wherein, from the current value of a tool driving motor, a correction moving amount, in the direction of the radius of a workpiece, of a tool responding to a resilient deformation amount of the workpiece is calculated to add it to a target moving amount. CONSTITUTION:A resilient deformation amount of a rolling roll produced due to a grinding work, in the direction of radius on the rolling roll, of a rotary grinding stone is calculated as a correction cut amount D of the rotary grinding stone by means of a resilient deformation correction means 62 based on a detecting current value detected by a current detecting means for a motor 24 for rotating a grinding stone. By adding the calculated correction cut amount D to a target cut amount R, a decrease in a grinding amount (a cut amount) due to resilient deformation of the rolling roll is corrected, and the rolling roll is ground in a desired shape by means of a normally accurate grinding amount.
