ABSTRACT:
A cutting insert includes a planar body member formed unitary with peripheral ledges of smaller width than the body member, with the ledges being configured and aligned relative to the body member to achieve desired rake angles, both axial and radial as well as the clearance angle desired of the cutting geometry. In operation, each elongated ledge defines the cutting edge of the cutting insert and during operation of the cutting insert, the ledge is consumed and thus generates a fresh edge behind it along the entire length of the ledge such that the cutting process may be maintained continuous until the entire length of the ledge is consumed. The cutting insert may then be indexed to the next ledge cutting edge.
