摘要
Roughing and finishing machining operations are carried out with a cutter insert (10) having at least one principal cutting edge (13) for roughing and an auxiliary cutting edge (14), in the form of a convex curve and adjacent to a planar flank (19), for finishing. Preferably the auxiliary cutting edge is curved with a radius of 40-50 mm and chip-forming groove extends parallel to the auxiliary cutting edge over its complete length. Its rake angle is 10-20 degree, preferably 15 degree. Radius of the chip forming groove is preferably 0.5-0.8 mm.
