Abstract

Procedure for the control and regulation of the sweep in the working gap of machines for electroerosive machining that have a pulse generator with an independent control to produce the working pulses, which is provided with a source for the ignition voltage as well as a main voltage source with lower voltage or lower internal resistance than the ignition voltage coil, characterized by the creation of a control signal, for which maximum values of the spark voltage as corresponding new values of the control signal are they transmit to this and between successive transmissions of this type the control signal passes according to predetermined interpolation functions and always dependent only on the value transmitted in principle from the signal, by the formation of an average value signal established through various periods of work impulses based on the control signal and by the initiation of a r sweep enhancement when the default mean signal differs from a reference signal.
