Abstract

L'invention concerne un procédé de rodage pour l'usinage de la surface interne d'un trou dans une pièce à l'aide d'au moins une opération de rodage, pendant laquelle un outil de rodage pouvant s'élargir est déplacé vers le haut et le bas dans le trou en vue de générer un mouvement vertical dans le sens axial du trou et tourné en même temps pour générer un mouvement rotatif superposé au mouvement vertical. Un trou en forme de bouteille est ainsi généré, qui présente ensuite, en une entrée du trou, une première section de trou dotée d'un premier diamètre, une deuxième section de trou, à l'opposé de l'entrée du trou, dotée d'un deuxième diamètre, qui est supérieur au premier diamètre, et entre la première et la deuxième section de trou une section de transition présentant une transition continue du premier au deuxième diamètre. Lors d'au moins une opération de rodage, on utilise un outil annulaire (200) qui présente au moins une nervure de coupe (220) annulaire présentant plusieurs corps en matériau de coupe répartis à la périphérie d'un corps d'outil, radialement réglables qui sont conçus comme des segments de rodage larges dans le sens périphérique et étroits dans le sens axial, une longueur axiale mesurée dans le sens axial des segments de rodage étant plus petite que la largeur mesurée dans le sens périphérique et la longueur axiale de la zone de coupe équipée des corps en matériau de coupe étant plus petite que le diamètre externe utile de l'outil de rodage. Le procédé convient en particulier pour le rodage de surfaces de glissement de cylindres lors de la fabrication de blocs-cylindres ou de chemises de cylindre pour machine à pistons.
