Claim 0:
1. A milling insert for a side and face milling tool, comprising:
an upper side having a rake surface and defining an upper extension plane;
a lower side opposite the upper side, the lower side defining a lower extension plane , wherein a center axis extends perpendicularly through the upper and lower extension planes;
a side surface extending between the upper side and the lower side around a periphery of the milling insert, wherein the side surface includes a main radial clearance surface, two opposite secondary axial clearance surfaces, and two corner clearance surfaces extending between the main radial clearance surface and the secondary axial clearance surfaces; and
at least one cutting edge formed in a transition between the upper side and the side surface, wherein each cutting edge includes a main cutting edge formed in a transition between the rake surface and the main radial clearance surface and two corner cutting edges formed in a transition between the rake surface and the corner clearance surfaces, wherein the main cutting edge, as seen in a side view of the milling insert, slopes downward from the corner cutting edges toward a midpoint of the main cutting edge, and wherein the main cutting edge, as well as the main radial clearance surface, as seen in a top view of the milling insert, both slope outward from the corner cutting edges toward the midpoint of the main cutting edge, wherein a shape of the main cutting edge as seen in the top view and a shape of at least an upper portion of the main radial clearance surface as seen in an arbitrary section perpendicular to the center axis are identical or essentially identical.
