ABSTRACT:
A cutting insert (20) for chip forming machining has at least one cutting edge (21) created by the transition between an upper face (22) and a side face (23) of the cutting insert (20), said upper face (20) being a rake face and the side face (23) being a flank. The rake face comprises a chip upsetting face arranged adjacent to the cutting edge (21) and a curved chip breaking face (25) arranged adjacent to the chip upsetting face (24). A number of mutually separated along and inside of the cutting edge (21) located depressions (27) are arranged to bridge a border line (26) between the chip upsetting face (24) and the chip breaking face (25).
