TANGENTIAL MOUNTED INSERTION INSERT WITH SEGMENTED CUTTING EDGE AND TRIANGULAR SHAPED EDGE

摘要

Cutting insert having two opposite end faces, two identical opposite major side surfaces, and two identical opposite minor side surfaces. Each end face has four corners comprising two lowered corners and two upstanding corners, the two lowered corners lying diagonally opposite one another, with the two upstanding corners facing each other diagonally. The cutting insert also includes a major cutting edge formed on a line of intersection of each major edge and the face. A portion of the major cutting edge near the upstanding corner represents a leading end of the major cutting edge and a portion of the major cutting edge near the lowered corner constitutes a trailing end of the major cutting edge. An angled edge extends only partially along the forward end of the major cutting edge and segments the major cutting edge.
