Patent ID: 8500376

Claim:
A cutting insert for chip-forming machining, of which at least the top surface, on one side, constitutes the face and the full-perimeter, planar side surfaces, which are located at right angles to one another, constitute the flanks, wherein, after a planar face portion that is adjacent to the flanks and is arranged at a rake angle of 0°, the face tapers, via downwardly sloping planar wall portions , into a lower-level, planar chip-forming base and, in the direction of the center, it slopes up, via upwardly sloping planar wall portions, to a centrally located, planar face plateau wherein a plurality of raised chip-forming elements are arranged parallel to one another, and at equal spacings, on two mutually opposite, upwardly sloping wall portions of the face plateau which chip-forming elements have a top surface, which slopes downward to the chip-forming base and downwardly sloping flanks.
