CUTTING INSERT WITH CHIP DIVIDERS

摘要

A cutting insert includes a polygonal body having an upper chip surface, a bottom surface and peripheral side surfaces extending between the upper chip surface and the bottom surface, the peripheral side surfaces intersecting the upper chip surface to form cutting edges therewith. A plurality of chip dividers are spaced apart about a perimeter of the upper chip surface to divide the chips produced by the cutting edges, each chip divider including a leading chip dividing portion adjacent to the cutting edge and extending generally upwardly from the cutting edge, the leading chip dividing portion having an elongated, rounded face. Adjacent chip dividers define a pocket such that the pockets are configured for promoting curling of chips produced by the cutting edges.

主权项

1. A cutting insert for cutting a workpiece by removing chips of material therefrom, comprising:
a polygonal body having an upper chip surface, a bottom surface and peripheral side surfaces extending between the upper chip surface and the bottom surface, the peripheral side surfaces intersecting the upper chip surface to form cutting edges therewith, and land surfaces disposed adjacent the cutting edges; and a plurality of chip dividers disposed about a periphery of the upper chip surface to divide the chips produced by the cutting edges, each chip divider including a leading chip dividing portion having an elongated face and extending generally angularly upwardly adjacent to the land surface, wherein adjacent chip dividers define a pocket configured for promoting curling of the chips produced by the cutting edges, the pocket having a rake face adjacent the land surface, opposing side walls extending upward from the rake face and a generally arcuate back wall interconnected with the rake face and the opposing side walls.
