A simplified post process for wire cut EDM

Abstract The paper deals with a technical realization to improve the Wire EDM accuracy while cutting at full speed on virtually any contour. The system which is readily available on commercial wire EDM machines is based on the on-line monitoring and control of the wire position by means of an optical sensor. The deviation of the wire position relative to the programmed wire path position is continuously measured and corrections are made during the machine cutting. Compared to conventional wire EDM machines, this technique allows to cut complex shapes, arc paths and contours at much faster cutting speed. Practical examples are discussed and the economical relevance is emphasized.
