Abstract

PRECIS DE LA DIVULGATION:
Nouvelle plaquette amovible de coupe de forme polygonale équilatérale non équiangle destinée à écrouter sans centre des matériaux bruts d'étirage ou laminage, par montage radial sur une tête multi-outils tournante, caractérisée en ce qu'elle comporte le long de chaque arête principale de coupe, deux surfaces brise-copeaux contigues constituées de gorges concaves distinctes.
La première est en regard de la partie rectiligne de l'arête prin-cipale de coupe. L'axe directeur de la surface est parallèle à
ladite arête et celle-ci forme un angle de coupe .alpha.. La deuxième est en regard de la partie rayonnée de l'arête raccordant l'arête principale de coupe à l'arête secondaire de planage, a un axe directeur perpendiculaire au plan bissecteur de la pointe de coupe rayonnée et forme un angle de coupe .alpha.2 La plaquette de coupe, selon l'invention, assure la formation d'un copeau ayant une section non rectiligne présentant au moins un point de flexion, ou encore la formation de deux copeaux en diminuant l'énergie transmise par la plaquette lors de la formation dudit copeau, tout en facilitant son enroulement, son fractionnement et son évacuation.
