摘要： An electrical discharge machine for applying a pulsed voltage to a machining gap between an electrode and a workpiece disposed opposite thereto. An insulating dielectric fluid, such as oil or water mixed with a compound additive, is disposed in the gap. A positive polarity voltage and an opposite polarity voltage are applied via switches and respective impedances to the machining gap in order to generate a discharge for machining the workpiece. A pulse having a first polarity is applied to machine the workpiece and a pulse having a second polarity is applied when the first polarity pulse is not applied. A misfire pulse detector detects an undesired drop in the machining voltage by determining whether the first polarity voltage is in a range between two voltages, the first of which has a magnitude greater than the magnitude of the machining gap during discharge and the second of which has a magnitude greater than the magnitude of the first voltage.

A machining operation starting position detecting unit detects the starting position for the machining operation at a k-th step. A machining position comparison unit compares them with each other. If the difference between them is less than a predetermined value, a signal is output to a machining condition changing unit and a control valve. As a result, the machining condition is changed, and a powdered substance is fed into a working fluid.

摘要： An electrical discharge machine for applying a pulsed voltage to a machining gap between an electrode and a workpiece disposed opposite thereto. An insulating dielectric fluid, comprising an oil or water with compound additive, is disposed in the gap. A positive polarity voltage and an opposite polarity voltage are applied via switches and respective impedances to the machining gap in order to generate a discharge for machining the workpiece. The impedance values may be selectively set and the switching of the voltages controlled such as to apply a positive polarity voltage at the stop time of an opposite polarity pulsed voltage, whereby the average voltage approximates a predetermined value, preferably zero, during the stop time. Voltage control during the stop time will result in high speed and finish, especially for control in connection with a jump operation.
