PCT No. PCT/EP95/04130 Sec. 371 Date May 15, 1997 Sec. 102(e) Date May 15, 1997 PCT Filed Oct. 21, 1995 PCT Pub. No. WO96/15869 PCT Pub. Date May 30, 1996A cutting insert for machining workpieces (preferably of metal) while removing the cuttings including at least one cutting edge (10) in the transition region between a rake (16) and a flank (18); the rake (16) comprises a flat face section (20) which is substantially parallel to the cutting edge (10) and several dome-shaped recesses aligned in a row and separated by gaps, the recesses being parallel to the cutting edge (10), and moulded into the face section (20) and partially penetrating the cutting edge (10). To ensure the uninterrupted removal of cuttings when short cuttings are produced, the invention proposes that a cutting form step (24) is provided on the face of the recesses opposite to the cutting edge (10). The cutting form step rises above the face section and is bounded by a bottom boundary line (26) on the cutting edge side and by a top boundary line (28) on the side away from the cutting edge. |
