Abstract: PURPOSE: An EDM(Electric Discharge Machining) electronic circuit is provided to control a reverse EDM by quickly applying a positive voltage to a gap between a tool electrode and workpiece for a short amount of time and by applying a negative voltage for an extended period of time. CONSTITUTION: An EDM(Electric Discharge Machining) electronic circuit(P) comprises a workpiece electrode(W), a tool electrode(T), first and second power sources(V1,V2), and a switch. The workpiece electrode is connected to the workpiece. The tool electrode forms a gap from the workpiece. The tool electrode is connected to the tool for processing an electric discharge. The first power source supplies a first voltage. The second power source is formed in a different branch passage and supplies a second power source. The switch generates a high frequency bipolar pulse type gap voltage using first and second voltages.
