ABSTRACT:
A cutting insert for use with an indexable cutting tool is formed from a flat wafer of cutting material which is generally polygonal in plane form and includes a pair of opposed faces and a plurality of upstanding side walls extending therebetween. The juncture of the side walls with each face defines the cutting edges of the insert. The polygonal insert which includes a plurality or radiused corner portions, is provided with at least one nonplanar insert face wherein the corner portions thereof slope inwardly towards the opposed face of the insert. Each corner portion further includes a pair of generally triangular chip grooves separated by a raised central triangular land area. Each chip groove is spaced from the peripheral cutting edge of the insert to define side land areas which increase in width from the corner portion to their opposed ends. The chip grooves increase in both width and depth from the corner portions to their opposed ends. The unique chip groove arrangement functions to reduce the forces imposed on the insert and enables the insert to be utilized over a wide range of feed rates and at various cuttng depths and chip loads, while simultaneously increasing the life of the insert.
