PCT No. PCT/JP81/00403 Sec. 371 Date Aug. 26, 1982 Sec. 102(e) Date Aug. 26, 1982 PCT Filed Dec. 23, 1981 PCT Pub. No. WO82/02354 PCT Pub. Date Jul. 22, 1982.The flexure value of a wire electrode in a machining tangential direction and the flexure value in a radial direction are obtained by a computerized numerical control device using the wire electrode speed of an electric discharge machine, the width of a machined groove and the flexure value during straight machining. The corrected position of the wire electrode is calculated using the above two flexure values. Distributed pulses are provided by pulse distributors on the basis of the calculated movement values relative to a current position, and servo motors in the electric discharge machine are driven by the distributed pulses fed through moving direction controllers, thereby to perform shape compensation in wire-cut electric discharge machining. |
