Beschreibung
Zusammenfassung:	A working route (21) of a main shaft is divided into a plurality of measurement points, and a length from a center (24) of a complete round (20) to the working route (21) 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 (20) to operate a deviation amount (D1, D2) from the complete round (20) at each of the measurement points. This deviation amount (D1, D2) is transferred symmetrically about the complete round in a radial direction of the complete round (20) to find a transferred position (28, 28A). As correction values for correcting the deviation value (D1, D2), 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.
