| Abstract: | This paper describes the design of PDC reaming drill bit for deep hole. With the reference to full face drilling PDC drill bit design theory, the theoretical researches on the design of crown profile and equal-cutting volume theory are made; using three-dimensional software integrated with Pro/ENGINEER CAD/CAM/CAE ion, the PDC reaming drill bit 3D modeling is completed. The parametric design improves the accuracy of PDC bit cutter placing, and PDC reaming drill bit can be applied in all kinds of reaming construction with very broad application prospects. |
