Abstract

See full text

A method for manufacturing a machine component having a rotation symmetry plane includes machining a rotation symmetry plane. The machining a rotation symmetry plane includes determining a track of the cutting. The determining a track determines the track in accordance with a condition that (1) a first end portion of the cutting edge is positioned at a cutting start position of the rotation symmetry plane, (2) N regions defined by division of the cutting edge successively come in contact with the rotation symmetry plane, (3) an inclination of a tangent line at a point of cutting of each of the N regions is equal to a target inclination of a tangent line which passes through the point of cutting and comes in contact with the rotation symmetry plane in a cut plane of the rotation symmetry plane, and (4) a second end of the cutting edge is positioned at a cutting end position of the rotation symmetry plane.
