| Abstract: | In this paper,an experimental study on the wear and brittle fracture of Polycrystalline Diamond Compact (PDC) bits during rock cutting was described. The effects of the rake angle of bit, bit forces, cutting speed, and depth on the wear and damage of bits were analyzed, the mechanism of failure of PDC bit was discussed, and some interesting results were given. |
