Abstract
A cutting insert includes a generally polygonal body having minor flank faces, major flank faces, chip breaking faces, major cutting edges formed at the intersection of the first faces and the major flank faces, and minor cutting edges formed at the intersection of the first faces and the minor flank faces. The major cutting edges are generally orthogonal to each other such that each major cutting edge can be alternately exposed for use. In one embodiment, both the major and minor cutting edges are generally linear. In another embodiment, the major cutting edges are generally curvilinear and the minor cutting edges are generally linear.
Claims14
A cutting insert, comprising:
- a generally polygonal body having minor flank faces, major flank faces, chip breaking faces between the minor and major flank faces, first faces between the major flank faces and the chip breaking faces, major cutting edges formed at the intersection of the first faces and the major flank faces, and minor cutting edges formed at the intersection of the first faces and the minor flank faces, wherein the chip breaking faces include chip deflecting surfaces extending away from the first faces and toward the minor flank faces, the chip deflecting surfaces assisting in curling and breaking chips as the chips flow over the chip breaking faces, and wherein the major cutting edges are substantially perpendicular to each other such that each major cutting edge can be alternately exposed for use.
A cutting tool, comprising:
- a generally polygonal body having minor flank faces, major flank faces, chip breaking faces between the minor and major flank faces, first faces between the major flank faces and the chip breaking faces, major cutting edges formed at the intersection of the first faces and the major flank faces, and minor cutting edges formed at the intersection of the first faces and the minor flank faces, wherein the chip breaking faces include chip deflecting surfaces extending away from the first faces and toward the minor flank faces, the chip deflecting surfaces assisting in curling and breaking chips as the chips flow over the chip breaking faces, and wherein the major cutting edges are substantially perpendicular to each other such that each major cutting edge can be alternately exposed for use;
- and
- a tool holder including a pair of jaws having surfaces defining a retaining slot therebetween.
