ABSTRACT:
A one-piece indexable cutting insert for a machine tool and method of machining therewith. The insert has opposed support faces and side walls, with the side walls being provided with cutting edge portions along spaced lengthwise edges. Each cutting edge portion includes a pressure land intersecting the side wall and extending inwardly therefrom, a relief land inboard of the pressure land and a chip breaker groove inboard of the pressure land. The pressure lands diverge from the side wall at such an angle that a normal to one of the pressure lands is directed into an opposed support face inboard of the chip breaker groove thereof. The method includes the steps of mounting the insert in the machine tool with one of said pressure lands in cutting relation to the workpiece and an opposed support face in supported relation, advancing the workpiece and the cutting insert in cutting relation to effect metal removal from the workpiece and causing forces on said one of the pressure lands to be directed into the opposed support face where the opposed support face is supported.
