DISPOSITIF DE COMMANDE AUTOMATIQUE D'UNE MACHINE-OUTIL A ELECTRO-EROSION

摘要

The device for automatic control contains a unit (1) for obtaining a signal which is proportional to the impedance of the erosion gap (2), and a reference-voltage source (5) which unit (1) and reference-voltage source (5) interact with the feed drive for the tool electrode. The device also has a transmitter (9) for the reactive component of the impedance of the erosion gap (2), which transmitter (9) is connected to the output (6) of the unit (1), and an electrical circuit (10) for regulating the consumption of the active fluid, to whose input the transmitter (9) is connected and whose output (12) is connected to the active process (13) of a mechanical system (14) in order to regulate the consumption of the active fluid circulating via the erosion gap. <IMAGE>
