Abstract
Official abstract text for this publication.
A cutting insert has a cutting edge formed at an intersection of a rake surface and a relief surface, with a chip-control arrangement located at the rake surface. The chip-control arrangement includes a plurality of recesses that extend downwardly into the rake surface and a plurality of projections that extend upwardly from the rake surface. The plurality of recesses follow a pattern of increasing depth in a rearward direction from the forward portion of the cutting edge. The plurality of projections follow a pattern of increasing height in a rearward direction from the forward portion of the cutting edge.
