Abstract

PURPOSE:To have an automatic discharge processing, quick and stable, by narrowing the search steps in the searching range with a larger change in the effective discharge rate with respect to discharge processing conditions. CONSTITUTION:This arrangement is composed of puosed power source 1, electrode 2, workpiece 3, effective discharge generation rate sensing circuit 4, searching range setting control circuit 11, etc. The output signal of a decoder 14 is placed into a coil of a relay to swtich over the signal for normal search step widths given by a D/A converter 13 to the signal for smaller search step widths given by voltage dividing resistances 15, 16 and a differential amplifier 21, or vice versa. The discharge processing is performed with the signal at the terminal 23 for output of the setting voltage control signal at certain specified processing spacings fed to an electrode feed servo circuit. According to this arrangement, an automatic discharge processing can be made rapidly and stably.
