Method and device for calculating an offset direction and a tilt direction of the wire electrode of a wire electro-discharge machining apparatus

摘要

Method and Apparatus for calculating an offset direction of a wire electrode using inputted offset data which contains the information as to whether the wire electrode should be offset on the inner side or outer side of the theoretical position. The offset data and the advancing direction of the wire electrode are used to determine whether the wire should be offset on the left or right side of the theoretical position.
