Document Type and Number:
Japanese Patent JP6679599
Kind Code:
B2
Abstract:
A method for manufacturing a machine component having a rotation symmetry plane includes machining a rotation symmetry plane by feeding a linear or curved cutting edge while the cutting edge is in contact with a point of cutting of the rotation symmetry plane. The machining a rotation symmetry plane includes determining a track of the cutting edge and feeding the cutting edge along the track. 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 (N being an integer not smaller than 2) regions defined by division of the cutting edge successively come in contact with the rotation symmetry plane, (3) a first inclination corresponding to an inclination of a tangent line at a point of cutting of each of the N regions is equal to a second inclination corresponding 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 including a Z axis representing an axial line of rotation and the point of cutting, and (4) a second end of the cutting edge is positioned at a cutting end position of the rotation symmetry plane.
