    摘要： A cutting insert for metal cutting includes a body portion of a generally polygonal shape having a cutting end including a front end wall, sides, and top and bottom surfaces. The intersection of the top surface, end wall and sides forming a cutting edge. The top surface includes a cutting land sloping downwardly and inwardly from the cutting edge, a chipgroove area adjoining the cutting land and extending inwardly therefrom and disposed at a lower elevation than the cutting edge, and an upsloping chipbreaker portion adjoining the chipgroove area and the cutting land and leading to a plateau disposed at a higher elevation than the cutting edge and chipgroove area. The chipbreaker portion is configured symmetrically about a line bisecting the top surface between the sides and includes a forwardly extending fingerlike projection on either side of and continuous with a rearwardly recessed region bisected by the line.

    摘要： A polygonal indexable cutting insert for cutting aluminum metal comprises rounded cutting corners with adjacent side surfaces joined at an angle of from about 33 to about 35 degress. Grooved recesses extending along each cutting edge have a particular geometry which includes a shallow descending surface followed by a steeply descending surface leading to the bottom of the grooved recess. An ascending surface directs the chip upwardly toward the top face and away from the insert and the cutting edge.

    摘要： A two cutting edge, indexable insert with integral pressed-in chip breaker wherein the cutting edges are symmetrically inverted relative to each other to thereby provide indexing therebetween. Each cutting edge is provided with a plurality of noses and gullets. The shape of the noses and gullets is predetermined to provide a predetermined thread contour, such as a buttress thread form. Each pressed in chip breaker is spaced from the adjacent cutting edge by a land and is in the form of a raised island having an incident face contour corresponding to the nose-and-gullet shape of the adjacent cutting edge. Each land is angled such that when the insert is mounted for use with an intended inclination, portions of the land are at neutral rake when engaging a workpiece.

    摘要： An indexable cutting insert having a polygonal body including top and bottom surfaces connected by a peripheral wall having sides and corners. In a generally diamond shaped embodiment, opposite acutely angled corners and the adjacent sides form cutting edges at their junctures with the top surface, forming noses at the corners. A narrow cutting land extends inward from each cutting edge and slopes downward from the nose along both adjacent sides. A chip groove includes a pair of wedge faces, sloping downwardly from the cutting land to a flat floor and a radius blend juncture aligned with the nose and bisecting the adjacent sides. A pair of chipbreaker faces slope upward from the flat floor and backward from a ridge that connects the chipbreaker faces and is upwardly aligned with the juncture of the cutting faces. Various additional features are also disclosed.

    摘要： An indexable threading and turning insert with integral press-in chip breakers, having a threading insert portion and a turning insert portion. Each of the threading insert portion and the turning insert portion has, respectively, an integral pressed-in chip breaker having ideal chip management characteristics. The indexable threading and turning insert has a substantially diamond shape having a first planar face, an opposite second planar face, and four insert faces extending between the first and second planar faces. The threading insert portion is characterized by a first cutting edge formed at the intersection of the first insert face and a first land and a second cutting edge formed at the intersection of the second insert face and a second land. The first and second cutting edges have a plurality of noses separated by gullets. First and second integral, pressed-in chip breakers, each in the form of a raised island, the incident face contour thereof corresponding to the nose-and-gullet contour of the respective cutting edge adjacent thereto. The turning insert portion is characterized by third and fourth cutting edges located, respectively, at the intersection of a third land with the third and fourth insert faces, and at the intersection of a fourth land with the third and fourth insert faces. Third and fourth integral, pressed-in chip breakers, each in the form of a raised island corresponding to the contour of the respective cutting edge adjacent thereto.
