Abstract

A working route of a main shaft is divided into a plurality of measurement points, and a length from a center of a complete round to the working route of the main shaft at each of the measurement points is measured, and this measured value is compared with a radial length of the complete round to operate a deviation amount from the complete round at each of the measurement points. This deviation amount is utilized to find a transferred position. As correction values for correcting the deviation value, an X-axis incremental amount and a Y-axis incremental amount obtained from a difference in the transferred position between the respective measurement points, or an X-axis absolute value and a Y-axis absolute value of the transferred position at each of the measurement points are incorporated into an NC working program to perform complete round working according to the program.
