  • Cutting insert with a rounded corner
    Patent number: 5904450
    Abstract: A cutting insert (1) for use in a milling cutter for a face milling has upper, lower and side surfaces and at least one pair of main and minor cutting edges (10, 11) formed by the intersection between the upper surface (5) and an adjacent side surface (7). The cutting edges (10, 11) merge via a cutting corner portion (12) of a relatively large radius, which is provided with a land (15) formed at the upper surface (5) of the insert. The land (15) is inclined to the insert lower surface at an inclination angle which continuously varies from a negative value at an area of the corner portion (12) adjacent the main cutting edge (10) to a positive value at an area of the corner portion (12) adjacent the minor cutting edge (11).
