CUTTING TOOL INSERT AND CUTTER BODY

摘要

A cutting tool (10) having a plurality of cutting inserts (12) mounted about the periphery of a cutter body (16) The insert (12) has radially extending projections (50) each including a front cutting edge (52) and rear cutting edge (21) Front and rear cutting edges from different adjacent projections together define an indivitual cutting side of the insert The cutter body (16) has a pocket (14) for each insert (12) The insert engages the pocket side wall at multiple locations using only the front teeth (53) from two or more projections (50) This permits a single cutter body and pocket design to be used with different inserts and allow the inserts' radial rake angle (A) to be varied from one insert to the next by varying the front tooth height
