Abstract

a. Appareil d'étincelage et procédé de mise en oeuvre de cet appareil. b. L'appareil est caractérisé en ce qu'il comprend des moyens pour indiquer qu'une composante à radiofrequence de l'étincelle est au-dessus d'un niveau prédéterminé correspondant à un usinage satisfaisant afin qu'un ou plusieurs paramètres de fonctionnement de l'appareil soient réglés lorsque la composante à radiofréquence est en dessous dudit niveau prédéterminé jusqu'à ce que ladite composante soit au-dessus dudit niveau prédéterminé. c. Usinage de pièces.
