Abstract

QUAND ON USINE DES SURFACES DE PIECES QUI NE SONT PAS DIRECTEMENT ACCESSIBLES A L'OUTIL, DE TRAVAIL, PAR EXEMPLE EN RAISON DE JOUES EN SAILLIE OU DE SURFACES DE PAROI INCLINEES, ON UTILISE UN OUTIL D'USINAGE PAR L'ARRIERE COMPRENANT UNE BROCHE ROTATIVE14 PORTANT DES MOYENS DE COUPE15. LA PIECE7 EST DISPOSEE SUR UNE TABLE6 AVEC SA FACE ACCESSIBLE TOURNEE VERS LE BAS, LE DISPOSITIF D'ENTRAINEMENT2 DE LA MACHINE EST DISPOSE EN DESSOUS DE LA TABLE, ET ON FAIT PASSER LA BROCHE PAR UNE OUVERTURE16 DE LA TABLE DE TRAVAIL ET PAR UN PASSAGE17 DE LA PIECE POUR PRESENTER LES MOYENS DE COUPE A LA FACE7D NORMALEMENT NON ACCESSIBLE DE LA PIECE. PENDANT LE FONCTIONNEMENT, LES MOYENS DE COUPE15 SONT AMENES A EXERCER SUR LA PIECE UNE PRESSION DIRIGEE VERS LE BAS ET QUI EST TRANSFEREE A LA TABLE DE TRAVAIL6 ET ABSORBEE PAR CELLE-CI.
