Abstract
A cutting insert includes an upper, lower and side surfaces and at least one leading cutting edge and a trailing wiper edge formed at an intersection of the upper surface with the side surface. A corner separates the leading cutting edge from the trailing wiper edge. The top surface includes a plurality of planar rake surfaces that extend inwardly and downwardly toward a seating surface of the insert. The top surface also includes a plurality of chip deflecting surfaces extending inwardly and upwardly toward the seating surface to form a transition zone between adjacent rake surfaces. The rake surfaces form a land angle with respect to a line perpendicular to the leading cutting edges. Additionally, a back wall surface extends upwardly from the rake surfaces to the seating surface to form a transition zone between the rake surfaces and the seating surface.
