Abstract
In a wire electric discharge machine that machines a blade section of a cutting tool, in a state in which a rod-shaped reference jig is fixed to a rotary axis, a position on an outer circumferential surface of the reference jig is measured at each rotation position and stored. A rotational run-out error is calculated based on the stored rotational run-out position information, and a machining program is corrected to cancel the rotational run-out error.
