A wire electric discharge machine is configured to machine a workpiece by computing an electric current at the machining time before starting a main machining and compensating a power source voltage for machining. The wire electric discharge machine measures an average electric current and an electric discharge frequency at the machining time, in a measuring section in an approach before the main machining, and computes a peak current at the machining time. Further, an electric voltage of a machining power source is compensated by comparing the computed peak current at the machining, with a reference peak current. |
