Abstract
A cutting insert having a rake surface and a flank surface wherein there is a cutting edge at the intersection of the rake surface and the flank surface. The rake surface exhibits a sufficient degree of surface roughness so as to provide for microscopic chip control. The flank surface exhibits a sufficiently smooth (i.e., a mirror finish) so as to provide for a workpiece surface finish that approaches (or possibly reaches) the theoretical value attributable for the given cutting conditions.
