Abstract

Procédé d'usinage par électro-érosion et système pour sa mise en oeuvre, avec usinage du fond de l'empreinte et usinage des flancs par mouvement latéral. Une résistance variable 122 constitue une image du niveau de l'électrode. Quand l'électrode atteint un niveau de référence, un relais 174 ferme une boucle 144 commandant, par les bornes Y1 , Y2 et AX1 , AX2 , une baisse du niveau de référence et une augmentation de l'amplitude du mouvement latéral, mais seulement si le relais 170 est excité par un signal FU témoignant d'une bonne fin d'usinage. Application à l'usinage par électro-érosion, notamment de pièces de forme complexe.
