摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device for manufacturing a machine component having a rotation symmetrical surface a ridge line of which forms a fixed angle larger than 0° and smaller than 90° with respect to a rotational axis, a computer readable recording medium, and a program.;SOLUTION: The manufacturing method includes the step of, in a three-dimensional orthogonal coordinate system where the rotational axis of a rotation symmetrical surface 1A is defined as a Z axis, the radial-direction axis of the rotation symmetrical surface is defined as an X axis, and an axis orthogonal to both of the Z axis and the X axis is defined as a Y axis, setting a linear cutting edge 2A inclined at an angle larger than 0° and smaller than 90° with respect to the Z axis at a cutting start position shifted from a position on the X axis along the Y axis direction, and the step of processing the rotation symmetrical surface 1A by feeding the cutting edge 2A in contact with a rotating machine component 1 along a track including an X-axis component, a Y-axis component and a Z-axis component from the cutting start position.;SELECTED DRAWING: Figure 20;COPYRIGHT: (C)2016,JPO&INPIT
