Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.
