Zusammenfassung
(EN)
An indexable cutting insert (a) for use with a cutting tool includes an insert body having a first surface (12) and a side relief surface (16a-d) defining a cutting edge (18) adjacent the intersection of the first surface and the side relief surface. A chip breaking structure (30) is interposed between the first surface (12) and the cutting edge (18). The chip breaking structure (30) includes first and second series of wedges (32 and 34). Each series of wedges is disposed inwardly from the cutting edge (18) and the wedge series (32 and 34) are disposed in orthogonal or normal relation to one another. In a preferred arrangement, the narrow edges (42) of the first and second series of wedges (32 and 34) are aligned with one another.

L'invention concerne une plaquette (a) de coupe amovible convenant pour un outil de coupe. Cette plaquette comprend un élément rapporté présentant une première surface (12) et une surface (16a-d) de dégagement latérale définissant un bord (18) de coupe adjacent à l'intersection entre la première surface et la surface de dégagement latérale. Une structure (30) brise-copeau est intercalée entre la première surface (12) et le bord (18) de coupe. Cette structure (30) brise-copeaux comprend une première et une seconde série de coins (32 et 34). Chaque série de coins est disposée à l'intérieur du bord (18) de coupe et les séries (32 et 34) respectives sont disposées de manière à présenter une relation orthogonale ou normale les unes vis-à-vis des autres. Dans une configuration préférée, les bords (42) étroits de la première et de la seconde série de coins (32 et 34) sont alignés.
