Abstract
A method of removing an end-surface burr of a formed groove cut into a workpiece by rotationally driving around an axial center and moving a formed rotary cutting tool relative to the workpiece in a direction orthogonal to the axial center, by using a formed rotary cutting tool for chamfering acquired by deforming a radial shape of the formed rotary cutting tool used in cutting of the formed groove according to a predefined chamfer angle, and by rotationally driving around an axial center and moving the formed rotary cutting tool for chamfering relative to an end surface of the formed groove in a direction perpendicular to the axial center along an axial center movement locus forming the chamfer angle relative to an axial center movement locus of the formed rotary cutting tool in the cutting of the formed groove, chamfering for removing a burr on the end surface is performed.
