Abstract
This invention describes an effective apparatus and method controlling the wire cutting process on EDM with the purpose to avert electrolyzing work piece and to improve mold quality, comprising pulse wave generator, negative low voltage power circuit, positive low voltage power circuit and negative high voltage power circuit; it control the discharge wave of the solid state electrical discharging machine, before the application of high voltage power, the low voltage power is first release to probe the gap of the work piece to attain proper judgment of whether it is normal discharge, arc discharge for open circuit, the regulate the high voltage discharge to achieve stable and high speed performance; basing the output of low voltage ignition phase shift control circuit and the polarity of shift ignition voltage to attain the appropriate AC ignition point.
