摘要： A polygon working method in which a polygonal portion can be formed on a workpiece in such a manner that a specific region of the polygonal portion is accurately in alignment with a predetermined circumferential position on the workpiece. In this method, the workpiece and a tool are simultaneously rotated in a manner such that a cutter of the tool is opposed to a circumferential workpiece position deviated from a predetermined circumferential position of the workpiece by the amount corresponding to the difference between a first positional deviation (PE1), which is produced during the time interval between the start of the rotation of a first main spindle (3a) fitted with the workpiece (1) and the establishment of a steady-state operation mode, in which the first and second main spindles (3a, 3b) rotate with a predetermined rotational speed ratio, and a second positional deviation (PE2), which is produced during the time interval between the start of the rotation of the second main spindle fitted with the tool and the establishment of the steady-state operation mode, and tool feed is started when the steady-state operation mode is established.
