<p>A cutting insert (20) has a cutting edge (26) formed at an intersection of a rake surface (28) and a relief surface (30), with a chip-control arrangement (22) located at the rake surface (28). The chip-control arrangement (22) includes a plurality of recesses (50, 74) that extend downwardly into the rake surface (28) and a plurality of projections (52, 72) that extend upwardly from the rake surface (28). The plurality of recesses (50, 74) follow a pattern of increasing depth in a rearward direction (DR) from the forward portion (25) of the cutting edge (26). The plurality of projections (52, 72) follow a pattern of increasing height in a rearward direction (DR) from the forward portion (25) of the cutting edge (26).</p> |
