摘要
An indexable cutting insert includes a top surface, a bottom surface and a plurality of side surfaces. Each side surface includes a first pair of chip grooves, and a second pair of chip grooves. A planar corner surface is disposed between each side surface. A corner radius extends between the top and bottom surfaces and the planar corner surface. A plurality of primary wiper cutting edges are formed at an intersection between each of the first pair of chip grooves and the top and bottom surfaces. A plurality of secondary roughing cutting edges are formed at an intersection between each corner radius and each of the first pair of chip forming grooves. A plurality of wiper cutting edges are formed at an intersection between each planar corner surface and each of the second pair of chip forming grooves. A milling cutter is also disclosed.
