Abstract
An indexable cutting insert comprises an upper surface, a bottom surface and side surfaces extending therebetween. Between two cutting corners, the rake surface is formed such that the rake angle is largest next to the two cutting corners and smallest at a point somewhere between the two cutting corners, preferably at or near the middle of the cutting edge. In this way, the cutting edge is strongest where the pressure load from the workpiece is largest, at the same time as a relatively small average rake angle is attained. This configuration decreases the cutting forces and the energy consumption.
