摘要

The invention relates to a polygonal cutting insert (10) with at least one longitudinally rib-shaped raised cutting component (13) on the face (19) arranged at a distance from the cutting edge (12) and extending longitudinally with a longitudinal axis (14) defined thereby and arranged substantially in the chip removal direction (14), whereby the longitudinal rib shape, looked at in the chip removal direction (31), is at its maximum (21) and the longitudinal rib (13) has a rising slope (20) towards the cutting edge (12) which broadens towards the regions away from the cutting edge and has the greatest width (b>2<) in the region of the maximum (21), the longitudinal rib (13) has a falling and narrowing upper surface (22) from the maximum (21) to the regions further away from the cutting edge (12) and the maximum (21) projects beyond the cutting edge (12).
