摘要： A wire electric discharge machine capable of preventing a straightness error from being caused by consumption of a wire electrode, to thereby eliminate insufficient machining. A correction angle null is predetermined for preventing the straightness error of the workpiece due to consumption thereof. Correction amounts d1null, d2null on a program plane and an upper surface of a workpiece, respectively, are determined based on the predetermined correction angle null, and are added to or subtracted from a predetermined offset amount depending on a wire electrode radius and an electric discharging gap, to thereby determine corrected offset amounts d1, d2 on the program plane and the upper surface of the workpiece, respectively. Correction amounts dlo, dup for lower and upper wire guides in an offset direction are obtained based on the corrected offset amounts d1, d2, respectively, so that motion paths of upper and lower wire guides relative to the workpiece are determined.

摘要： A method for adjusting the gap between an upper nozzle of a wire electric discharge machine includes placing a spacer member of a known thickness between a forward end of the upper nozzle and a workpiece. The forward end of the upper nozzle is brought into contact with the spacer member, so that the forward end of the upper nozzle is prevented from coming into direct contact with the workpiece. A Z-axis position of the upper nozzle is controlled on the basis of the thickness of the spacer member and the desired nozzle gap to set the gap between the forward end of the upper nozzle and the workpiece to a predetermined value. In controlling the Z-axis position of the upper nozzle, correction is made to compensate for a deformation of the upper guide, the spacer member, the workpiece, and the upper nozzle, and/or for a displacement of the upper guide resulting from a pressure of a working fluid.
