PROBLEM TO BE SOLVED: To eliminate influence on working quality due to bending of a burnishing tool. SOLUTION: When burnishing is applied to a round chamfering part Q of a work W by using a roller attachment 12 provided with a burnishing roller 16, moving locus data D1 of the burnishing roller 16 to follow the curvature of the round chamfering part Q is set in advance. When starting working, each of bending displacement when imparting low pressure to the attachment 12 and bending displacement when imparting high pressure is detected by a displacement sensor 19 to calculate bending amount n. Offset amount m is determined according to the bending amount n and the initial moving locus data D1 is offset to D2 according to the offset amount m. |
