PROBLEM TO BE SOLVED: To acquire working results similar to those where there is no installation error between the position of a workpiece assumed by a working program and the position of an actually installed workpiece, even when there is such an installation error and the installation error is gradually changing according as the workpiece rotates during working. SOLUTION: Interpolation is carried out with coordinate values before error correction is carried out, and error correction is carried out to the acquired position after interpolation for each interpolation point. Also, interpolation is carried out so that the relative speed of a workpiece and a tool can be made equal to the relative speed when there is no error, and when the actual speed of a machine exceeds a clamp speed as a result, the relative speed of the workpiece and the tool is adjusted so that the actual speed can be prevented from exceeding the clamp speed, and the relative speed is prevented from changing in the middle of block.
