A complete-circle operation of a machine tool controlled by an NC-device. Even if the NC-device gives operation commands for respective shafts of the machine tool on the basis of a control locus which is to be a complete circle, the actual operation locus of the machine tool is not a complete circle because the machine tool generates errors due to various causes such as thermal deformation, machine accuracy, etc. If the errors are corrected individually to improve the accuracy, the complexity of the processing cannot be avoided. It is assumed that the operation locus of the machine tool which is controlled for a complete circle becomes an ellipse due to errors involved. A simple process corrects the ellipse such that it is converted to a complete circle.
