    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: A cutting member comprising a cutting edge (S1,S2,Si) defining a cutting envelope and configured for removing material from a workpiece leaving therein a corner of angle α. The cutting edge comprises a first cutting segment (S1) and a second cutting segment (S2) spaced from the first cutting segment (S2). Respective first and second imaginary tangents (T1,T2) of the first and second cutting segments (S1,S2) intersect one another at point O located outside the cutting envelope, forming an angle corresponding to angle α, thereby defining a cutting frame at least a portion of which extends beyond the cutting envelope. The cutting edge further comprises an adjoining cutting segment (Si), extending between and bridging the first cutting segment (S1) and the second cutting segment (S2), and at least partially contained within the cutting frame. The cutting member further comprises at least one auxiliary cutting element (AT1,AT2) comprising an auxiliary cutting edge (CE′,CE″) extending generally along one of the imaginary tangents (T1,T2) and beyond the cutting envelope. The auxiliary cutting edge (CE′,CE″) does not intersect the other of the imaginary tangents (CE″,CE′) and/or a bisector (B) of the angle α.

    Abstract: A cutting insert includes a cutting edge formed at an intersection of a rake face formed on a first surface and a relief face with a positive relief angle. The relief face includes a major relief face located adjacent to a major cutting edge, a first minor relief face located adjacent to the first minor cutting edge, and an intermediate relief face located adjacent to the intermediate cutting edge and extending between the major relief face and the first minor relief face. The intermediate relief face includes a protruding curved relief face extending from the first surface. An intersection of the curved relief face and the rake face has a predetermined radius of curvature and has substantially the same shape as that of an intersection of the curved relief face and a second surface.

    Abstract: A milling insert (1) for chip removing machining, has a positive basic geometry, including at least three main cutting edges (H1-H3) and three associated minor cutting edges (B1-B3), the milling insert (1) on the underside (L1) thereof being provided with at least two, mutually intersecting, sets of rectilinear grooves/notches, the sets of grooves/notches defining essentially pyramidal projecting parts (P), the sets of grooves/notches intersecting opposite side surfaces (S1-S6) of the milling insert (1). A face milling cutter equipped with such milling inserts is described. Characteristic of the milling insert (1) is that when the milling insert is seen in a planar view, the rectilinear direction (R1-R3) defined by each set of grooves/notches forms a right angle with the tangent of a minor cutting edge (B1-B3).
