Abstract

Procedure for the regulation of the advance in spark erosion machines, in which a real value signal is derived from the spark voltage and after having compared it with a pre-established nominal value, the average value of the comparison signal is entered in the adjustment member of the advance regulation, characterized in that the real value signal is proportional to the proportion of effects η defined by the ratio between the erosion time and the pulse duration of an individual pulse.
