ABSTRACT:
A numerical controlled grinding machine for grinding a workpiece, in which a thermal displacement taking place between a wheel head and the workpiece, is detected with the workpiece not being subjected to the bending due to a grinding resistance. The thermal displacement is calculated from the difference between the present position of the wheel head detected by a position detector and the theoretical position thereof converted from the diameter of the workpiece measured by an in-process measuring device. The position data for the wheel head stored in a numerical controller is compensated for the calculated thermal displacement for use in the subsequent control of feed movement between the workpiece and the wheel head.
