Claim:
Cutting insert for chip removing machining of workpieces, comprising a body having opposite first and second surfaces interconnected by at least three side surfaces; wherein with the insert in an operative cutting state the first and second surfaces form a chip removing top flank surface and an inactive bottom flank surface, respectively; the top flank surface forming a cutting edge; the cutting edge including a generally convexly curved corner cutting edge portion which includes a nose intersected by an imaginary bisector of the corner cutting edge portion, and a surface-smoothing segment spaced from the bisector for smoothing a cut surface of the workpiece; the surface-smoothing segment including at least first, second and third part edge segments defined by first, second, and third radii, respectively which are larger than that of the nose; the first part edge segment disposed between the second and third part edge segments; each of the second and third radii being longer than the first radius.
