    Abstract: A milling insert includes a polygonal tubular insert body which has: rake faces on one polygonal surface thereof, flanks composed of circumferential surfaces adjacent to the polygonal surface, and cutting edges defining a ridge line where the rake faces and flanks intersect each other as cutting edges. The rake faces have serrations where mount portions and valley portions are arrayed alternately to intersect the cutting edges. The ridge line has a waveform shape when the flanks are viewed from above. Bottom portions and top portions of the waveform are formed into concave circular arc portions and convex circular arc portions, respectively, and are alternately repeated. Both of the concave and convex circular arc portions are a ¼ circular arc or more to a ⅓ circular arc or less. Each of the concave circular arc portions is unevenly located between the convex circular arc portions adjacent thereto.

    Abstract: Indexable insert has a non-rectangular parallelogram shape with nearly rhombic basic shape and an imaginary intermediate plane spanned by four corners of an imaginary rhombus with sides running at a distance away from the upper side and the underside along the peripheral lateral surface in a plane such that each equivalent cutting edge has the same variation of distance and angle from the intermediate plane. Two diagonally opposing corners of both the upper side and the underside each have a greater distance from the intermediate plane than do the respective diagonally opposing corners of the upper side and the underside lying therebetween, and the diagonally opposing corners of the upper side and of the underside are shifted parallel to the intermediate plane and, as viewed in a plan view onto the intermediate plane, in mutually opposite directions away from the associated diagonals of the rhombus spanning the intermediate plane.

    Abstract: An indexable cutting insert includes a top surface, a bottom surface, a plurality of peripheral side surfaces, and a plurality of cutting edges formed at an intersection between said top surface and plurality of side surfaces. A plurality of triangular-shaped serrations are positioned along the cutting edges, each serration comprising an apex and a pair of side surfaces that meet at a vertex. The serrations provide the cutting edges with both a positive axial rake angle and a negative axial rake angle, thereby reducing delamination when machining a composite material.

    Abstract: A cutting insert has a substantially polygonal shape, and a groove formed in a corner portion of one polygonal surface, and at an intersecting portion between a leading cutting edge and a peripheral cutting edge formed at intersecting portions of side surfaces adjacent to each other across the corner portion, a minor cutting edge is formed. Of the groove, in an area associated with the leading cutting edge and the minor cutting edge, a rake face including a downward inclined surface is formed. A first angle between a direction of maximum inclination of the downward inclined surface and the leading cutting edge is larger than a second angle between the direction of maximum inclination and the minor cutting edge.

    Abstract: A cutting insert having a plurality of corner cutting edges has an upper face, a lower face, two longitudinal side faces and two transversal side faces connecting the upper face and the lower face. A through hole passes through central parts of the upper face and the lower face. The longitudinal side faces are opposite to each other and normal to both upper and lower faces, as are the transversal side faces. The upper face and the lower face are each provided with two chip discharge grooves, each chip discharge groove extending along a corresponding one of the transversal side faces, the two chip discharge grooves being inclined oppositely in the transverse direction so that the upper face and the lower face are each provided with two corner cutting edges at diagonally opposite corners. The longitudinal length of the insert is longer than the transversal length of the insert. The cutting insert can be mounted stably to a small-diametered cutter with a sufficient mounting surface.
