ABSTRACT:
A cutting tool for improved chip forming material removal efficiency over a wide mid-range of typically used feed rates and depths of cut is disclosed in a preferred form of an indexable polygonal cutting insert. A first chip control groove of uniform width and cross section radius extends from a cutting edge at each side of the polygon and terminates inwardly from the edge in a second chip control groove having a cross section of larger radius but of lesser depth than that of the first chip control groove. The second groove has its largest width at a point substantially midway between adjacent cutting corners of the polygon and diminishes to zero width at the end of each straight cutting edge, the first groove continuing around a substantial corner radius adjoining adjacent ends of the straight portions of such grooves. Corner projections of the outer face of each side of the insert extend between adjacent ends of the second grooves providing a substantial mounting support for inserts incorporating chip control grooves in both major polygonal faces. The cutting edge along the side of the polygon is arcuate with its lowest point relative to a major face of the insert being substantially at a midpoint between each corner of the polygon.
