Abstract: This cutting insert is provided with a lower surface of polygonal shape including side parts and a pair of corner parts, an upper surface, a lateral surface situated between the lower surface and the upper surface, a pair of corner cutting edges located at the pair of corners, and a main cutting edge located in a side portion. The main cutting edge is upwardly convex in shape, and in side view includes an upwardly convex curving portion, and a pair of linear portions respectively extending toward the pair of corner cutting edges from the curving portion. The top portion of the curving portion is positioned more toward the one of the corner cutting edges which, of the pair of corner cutting edges, is that contiguous to a working surface of a work material during cutting of the work material.

Abstract: In a rotary cutting tool used for milling operations, a reversible cutting insert is removably secured in a cutting body. The cutting insert has two opposing end surfaces interconnected by a continuous peripheral surface, which includes three side surfaces alternating with three corner surfaces. The side and corner surfaces intersect with both end surfaces at side and corner edges, respectively, with each side edge having a major cutting edge, and each corner edge having a corner and minor cutting edge. Each minor cutting edge has a projected minor cutting length, in an end view, and each associated minor relief surface has a minor relief width between two lateral boundary points contained in a horizontal plane, varying with an offset distance between the horizontal plane and a median plane. Each projected minor cutting length is greater than the maximum minor relief width of its associated minor relief surface.

Abstract: A tangential cutting insert has three pairs of surfaces. A first pair has upper and lower surfaces, a second pair has front and rear surfaces, and a third pair has two side surfaces. The upper and lower surfaces and the side surfaces extend between the front and rear surfaces. A main cutting edge is formed at the intersection of the front surface with the upper surface. A front portion of the upper surface extends rearwardly from the main cutting edge and upwardly toward a central portion of the upper surface as seen in a side view of the cutting insert. The main cutting edge associated with the upper surface is curved and slopes downwardly toward each of the auxiliary cutting edges as seen in a front view of the cutting insert.

Abstract: The present invention is directed to a cutting insert with a rake face, a seating surface and a plurality of flank faces extending between the rake face and the seating surface. The intersection of the rake face and the plurality of flank faces define a plurality of cutting edges. The rake face of the insert has a plurality of corner regions formed at the intersection of side cutting edges to define corner cutting edges. The corner cutting edge in at least one corner region has a recessed profile when viewed from the side of the insert. The recessed profile has a concave shape and extends inwardly from the cutting edge. At the cutting edge, the recess has a conical shape to define a conical portion and further inward from the cutting edge the recess may have a cylindrical shape to define a cylindrical portion.
