PROBLEM TO BE SOLVED: To provide a cutting method or the like, which can prevent shape deterioration resulting from interference between a cutting tool and a target shape even in a case where a standing wall that is not uniform in direction along a radial direction during processing is formed.SOLUTION: In a processing method, while a workpiece W is rotated with respect to a cutting tool 80, the cutting tool 80 is relatively moved in a radial direction R, and in accordance with a blade edge position, which is the position of the blade edge 80a of the cutting tool 80 with respect to the workpiece W, the cutting tool 80 is displaced in the extending direction of a tool axis TX through which the blade edge 80 passes, thereby cutting the workpiece W. Here, a rotating position around the tool axis TX of the cutting tool 80 is adjusted in accordance with the blade edge position with respect to the workpiece W. Thus, even when a standing wall OW that is not uniform in direction along a radial direction R during processing is formed, interference between a target shape OF and a side part 80b of the blade edge 80a of the cutting tool 80 can be prevented.SELECTED DRAWING: Figure 3 |
