摘要：

To decrease polycrystalline diamond compact (PDC) cutter abrasion and improve the PDC bit’s drilling performance, based on the academic analysis, a series of rock cutting experiments were made on a lathe with a single PDC cutter to understand better the effects of cutting angle, height of protrusion, linear velocity and the indentation hardness on PDC cutter wear. By the experiments, it shows that the different cutting angles are suitable to different heights of protrusion; for example, the optimal protrusion height of PDC bit with cutting ang...
