摘要

In wire electric discharge machining, a wire electrode is continuously tilted right and left or forward and backward, based on a predetermined unit machining distance and a wire electrode tilt amount corresponding thereto, as machining is performed. By this machining, a machining amount for producing an indentation on the workpiece can be reduced and streaks that are produced during finish machining with low electric discharge energy can also be reduced.
