    Abstract: A cutting insert is formed with a substantially hexagonal cutting face having six sides forming three main cutting edges and three auxiliary cutting edges alternating with the main edges. Each of the main cutting edges is substantially straight and each of the auxiliary cutting edges is outwardly convex. A plateau is on the face inward of the cutting edges and defines a plane. Respective free surfaces each extend generally perpendicular to the plane from the cutting edges and meet at corners between the edges. The main cutting edges are usable for roughing and the auxiliary cutting edges for finishing. The insert is formed on the face along an entire length of and parallel to each of the cutting edge with a respective groove.

    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).

    Abstract: In a ball end mill, a rotational locus is described by cutting edges of respective throw-away tips mounted to a tool body. The cutting edge of one of the tips and the cutting edge of the adjacent tip overlap with each other, and the center of the overlapping portion is located at a position that is substantially 45.degree. from a forward end of the cutting edge along a 1/4 arc of the rotational locus therefrom. The overlapping length is 1/4 to 1/3 of a diameter of the rotational locus in an arcuate length thereof. A planar section is formed at a side surface of at least one of the tips, which is located at a forward end of the tool body. The side surface is located adjacent a forward end of the cutting edge. A planar surface is formed at at least one of the tip pockets formed in the tool body, at a position facing toward the planar section. The planar surface is subject to a radial cutting force acting from the throw-away tip having the planar section. The planar section is abutted against the planar surface.

    Abstract: A locking structure for locking a cutting insert to a tool holder, the insert having a generally hour-glass shaped lockscrew receiving aperture therethrough. The lock-screw is provided with a head having a lower section which flares outwardly from the shank, a central cylindrical section and an upper section which converges in generally frusto-conical fashion. The axis of the lock-screw receiving aperture in the tool holder is slanted toward the plane or planes of one or more locating abutments on the holder. The components, when assembled, provide a positive lockdown for the insert in the tool holder, force the insert positively against the locating abutment or abutments and, yet, permit the insert to be removed without complete removal of the lock-screw.

    Abstract: In a rotary cutting tool (52) used for milling operations, a reversible cutting insert (20) is removably secured in a cutting body (54). The cutting insert (20) has two opposing end surfaces (22) interconnected by a continuous peripheral surface (24), which includes three side surfaces (26) alternating with three comer surfaces (28). The side and comer surfaces (26, 28) intersect with both end surfaces (22) at side and comer edges (32, 34), respectively, with each side edge (32) having a major cutting edge (36), and each comer edge (34) having a comer and minor cutting edge (38, 40). Each minor cutting edge (40) has a projected minor cutting length (L M ), in an end view, and each associated minor relief surface (48) has a minor relief width (W) between two lateral boundary points contained in a horizontal plane (PH), varying with an offset distance (D O ) between the horizontal plane (PH) and a median plane (M). Each projected minor cutting length (L M ) is greater than the maximum minor relief width (W MAX ) of its associated minor relief surface (48).
