摘要： In the process of machining by electroerosion, there is adjusted during a first transitory phase the machining current increase of the discharges after triggering a discharge between the electrode and the piece, such that a parameter connected to this increase will be substantially equal to a reference value corresponding to a minimum wear value of the electrode. Then, the machining current is maintained during a second phase at a reference value. The adjustment is carried out by acting on the adjustable internal voltage of a low impedance adjustable voltage source connected between the electrode and the piece. The adjustment can be carried out by a servo control loop with a regulator of the internal voltage, a device for generating discharges, parts adapted to determine the slope of increase of the current of a discharge, a member determining the mean slope of N discharges and a member adapted to compute the difference between the mean slope and a pre-established reference slope.
