Abstract: A special end cutting edge attached cutter for carbon fiber reinforced polymer/plastic with designable micro-tooth configuration, having an end cutting edge, a peripheral cutting edge with variation inverse helical groove, a peripheral cutting edge with constant inverse helical groove and a shank. Two parallel V-shaped chip pockets are designed on the end cutting edge of the cutter in two cutting edge directions which are symmetrical around a cutter axis as a center. The structure may enhance chip removal performance during high-speed milling of impenetrable slots and impenetrable windows, reduce wear of the end cutting edge, conduct configuration design for micro-teeth of the peripheral cutting edge, reduce the cutting thickness of the micro-tooth cutting edges, and effectively solve the problem of damage of the micro-tooth edges. A section of peripheral cutting edge with variation left-hand inverse helical flute angle is designed near the end cutting edge.
