Method for machining cylindrical surfaces of parts by cutting and deformation and device for implementing it

Method and device for machining cylindrical surfaces both external and internal. The excess thickness of a surface of a part B is removed by the apexes C1, C2 of the sharp cutting edges of the cutting tools 1, 2. For this purpose, the apexes C1, C2 are offset with respect to one another by a distance A in the direction of longitudinal advancement and they are arranged at various distances relative to the rotational axis O-O of the part. This process enables fine non-staged adjustment of cutting tools both during machining as well as before starting machining as well as bringing the cutting head back without removing it or damaging the machined surface. PROCEDE ET DISPOSITIF POUR L'USINAGE DE SURFACES CYLINDRIQUES TANT EXTERIEURES QU'INTERIEURES. ON ENLEVE LA SUREPAISSEUR D'UNE SURFACE D'UNE PIECE B PAR LES SOMMETS C, C DES ARETES TRANCHANTES DES OUTILS DE COUPE 1, 2. A CET EFFET, ON DECALE CES SOMMETS C, C L'UN PAR RAPPORT A L'AUTRE D'UNE DISTANCE A DANS LA DIRECTION DE L'AVANCE LONGITUDINALE ET ON LES DISPOSE A DIFFERENTES DISTANCES PAR RAPPORT A L'AXE DE ROTATION O-O DE LA PIECE. CE PROCEDE PERMET D'EFFECTUER UN REGLAGE FIN NON ETAGE DES OUTILS DE COUPE TANT EN COURS D'USINAGE QU'AVANT DE COMMENCER L'USINAGE AINSI QUE DE RAPPELER LA TETE DE COUPE SANS LA DEPOSER NI ENDOMMAGER LA SURFACE USINEE.
