Title
(EN) GAPLESS CHIPBREAKER
(FR) BRISE-COPEAUX SANS ESPACE
Abstract
(EN)
Chip breaking features may be arranged in radial reliefs of a rotary cutting tool. The chip breaking features create gaps or voids in the otherwise continuous cutting edge, resulting in otherwise continuous chips being cut into discrete chips. The chip breaking features may be angled so as to define a secondary cutting edge. Depending on the angle at which the chip breaking features are angled, the secondary cutting edges may partially or completely close the gaps or voids in the cutting edge. Closing the gaps or voids in the cutting edge ensures that each blade removes nearly all material so the following blade does not have to clean up.
(FR)
Selon l'invention, des éléments de rupture de copeaux peuvent être disposés dans des reliefs radiaux d'un outil de coupe rotatif. Les éléments de rupture de copeaux créent des espaces ou des vides dans le bord de coupe, qui est, sinon, continu, ce qui a pour résultat la coupe de copeaux qui sont, sinon, continus, en copeaux distincts. Les éléments de rupture de copeaux peuvent être en angle de façon à définir un bord de coupe secondaire. En fonction de l'angle selon lequel les éléments de rupture de copeaux sont inclinés, les bords de coupe secondaires peuvent fermer partiellement ou complètement les espaces ou vides dans le bord de coupe. La fermeture des espaces ou des vides dans le bord de coupe garantit que chaque lame retire quasiment tout le matériau, de telle sorte que la lame suivante n'a pas besoin d'être nettoyée.
