Diamond composite materials and carbide cutting tool wear compared with
WC was significantly better than the performance of rock cutting pick. In the same cutting conditions, WC pick tool showing serious wear, but no significant wear TSDC pick. WC pick with cutting drum (or disc) was significantly greater than the thrust cutter drum with TSDC thrust. 4, the tool wear on from two different mechanisms acting on the cutting force. When the tool wear increases, the cutting depth will be reduced, which will lead to a decline in cutting force. But when the tool wear, with the corresponding increase of cutting force, friction will increase. Thus, cutting forces may increase or decrease, depending on which play a major role in cutting mechanism.
