    摘要： An indexable cutting insert of the type having a corner radius and a corner angle adapted for finishing operations comprises a pair of substantially parallel spaced apart faces and at least one peripheral side surface being substantially normal to said faces. A pair of straight cutting edge extend away from the corner at the juncture of the peripheral side surface and a plane positioned closely adjacent and below the juncture of a respective face. To break the chips formed during cutting, a chip breaker recess extents rearwardly and along the cutting edges. The chip breaker recess includes a descending control surface leading to the bottom of the recess followed by an ascending control surface. The descending control surface comprises a first and second planar descending control surface with the first surface being at a shallow angle and the second surface being at a steep angle. The ascending surface directs the chip upwardly toward a central island formed within the plane of a respective face and away from the insert and the cutting edge. The chip breaker recess incorporates an additional shallow chip control recess formed by a raised land extending outwardly toward a corner from the central island along a bisector of a respective corner and a raised bottom surface extending above the bottom of the main chip breaker recess and around the corner. The additional chip control surfaces forming the shallow recess include an ascending corner chip control surface extending upwardly from the raised corner bottom control surface at a relatively steep angle. The recess is configured to change the curling motion of the chip at various depths of cut to enhance the chip breaking forces.

    摘要： A chip control insert is disclosed having positive, concave radiused chip breaker entry surfaces, and a locating surface which is equipped with a planar sealing surface and inclined, convex, radiused chip breaker ramp surfaces which undulate along the length of the insert. The intersection of the back ramp surface and the entry surface defines a chip groove. The locating surface has radial nose projections and radius bulges intermediate the length of the polygon sides of the insert.

    摘要： A flat disk-like tool insert has a plurality of arcuate cutter tips for machining the side surface of a rotating work piece, and a plurality of linear cutting edges for machining a chamfer on the end of the work piece. An endless land surface is contiguous with the cutter tips and the linear cutting edges so as to deflect metal chips away from the machined surfaces. Each tool tip is aligned with two chip breaker ledges that are arranged in a step configuration, such that chips of varying thickness can be effectively and cleanly broken without interference with the machining process. A third chip breaker ledge is set back from each linear cutting edge for breaking chips generated during a chamfering operation.

    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： 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 corners and the adjacent sides form cutting edges at their junctures with the top surface, forming noses at the corners. A chip groove formed on the top surface includes a pair of cutting faces, sloping downwardly from respective sides to a radius blend juncture aligned with the nose and bisecting the adjacent sides. A pair of chipbreaker faces slope upward from respective ones of the cutting faces and backward from a ridge that connects the chipbreaker faces and is upwardly aligned with the juncture of the cutting faces. The chipbreaker faces preferably have a double curvature (1) outward from the ridge and (2) upward from radius blend junctures with their adjoining cutting faces. The upward curvature is preferably a radius that slopes upwardly at a declining rate with increasing distance from the respective cutting face junctures. A third cutting face at the nose adjoins the side connected faces preferably at a common angle. Various additional features are also disclosed.
