ABSTRACT:
In an electric discharge machine, a pulse voltage is applied between a wire electrode and a workpiece to cause electric discharge between said wire electrode and said workpiece in a work liquid, and said workpiece is moved to said wire electrode depending upon the configuration of said workpiece and the degree of said electric discharge work to obtain a desired configuration. The movement of said workpiece can be controlled depending upon the speed signal corresponding to a gap voltage and the degree of the signal. The size of the work area is detected by the speed signal and a sharp corner work is carried out under a low energy by controlling the power source and the thickness variation work is carried out by increasing the energy in the case that the work area is increased and by decreasing the energy in the case that the work area is decreased.
