Abstract

L'INVENTION CONCERNE UN PROCEDE POUR L'USINAGE PAR ETINCELAGE EROSIF D'UNE ELECTRODE-PIECE AU MOYEN D'UNE ELECTRODE-OUTIL. LA PENETRATION DE L'OUTIL DANS LA PIECE EST ARRETEE LORSQUE LE DEPLACEMENT RELATIF DE CES ELECTRODES ATTEINT UNE VALEUR DE CONSIGNE DETERMINEE. CETTE VALEUR DE CONSIGNE EST CORRIGEE EN FONCTION DE L'USURE REELLE DE L'OUTIL QUI EST MESUREE EN COMPARANT LES POSITIONS PRISES PAR L'ELECTRODE-OUTIL LORSQU'UNE DE SES SURFACES ACTIVES ATTEINT LA MEME POSITION DE REFERENCE AVANT ET APRES UNE PHASE D'USINAGE. LA CORRECTION DE CETTE VALEUR DE CONSIGNE PEUT ETRE OBTENUE SOIT PAR APPROXIMATIONS SUCCESSIVES, SOIT PAR UN CALCUL UNIQUE EFFECTUE APRES LA PREMIERE OPERATION D'USINAGE.
