Abstract
A cutting insert for grooving operations includes a shank portion and a forward cutting head. The shank portion includes an upper surface, a bottom surface and side surfaces, wherein a line of intersection between the upper side and a forward clearance face forms a main cutting edge. Between the main cutting edge and a secondary cutting edge there is provided a corner cutting edge. The corner cutting edge comprises a primary curved edge with a first radius extending from the main cutting edge, and a secondary curved edge with a second radius, larger than the first radius, that extends from the primary edge to a side edge and oriented perpendicular to the main cutting edge. The cutting insert also comprises an upper side confined by two longitudinal ridges and an elongated chip forming recess therebetween.
