Abstract
The invention relates to a method for electrical discharge machining of workpieces by electrical discharge pulses generated by a power module of an electrical discharge machine. The invention is characterized in that firstly the discharge voltage of a number Nof electrical discharge pulses is acquired and stored, secondly a front discharge voltage () is determined out of this amount of Nacquired discharge voltages and thirdly, the voltage Uhps () of the electrical discharge pulses produced by the power module for machining the workpiece () is adjusted in function of the determined front discharge voltage ().
