Abstract
A cutting insert for chip forming machining of metal workpieces, especially for milling, has an upper face, a lower face and edge faces intersecting the upper face to form cutting edges. A chip upsetting face extends inwardly from the cutting edge and a concavely curved chip face extends inwardly from the chip upsetting face to form a transition edge therewith. The upper face is provided with a number of depressions which are spaced apart along the transition edge. The depressions intersect the transition edge and extend inwardly therefrom. The depression extend non-perpendicularly relative to the cutting edge to form an acute angle with a line perpendicular to the cutting edge. The acute angle is in the range of 5 to 45 degrees. During a cutting action in the depressions cause runners to be formed on the chip bottom, and the runners tend to climb up the sides of the depressions.
