摘　　要：介绍了深孔PDC扩孔钻头设计方法,参考了全面钻进PDC钻头设计理论,进行了冠部轮廓设计及等切削布齿理论研究,借助CAD/CAM/CAE一体化三维软件Pro/ENGINEER完成PDC扩孔钻头三维建模,参数化设计提高了PDC布齿的准确性,PDC扩孔钻头可应用到各种扩孔施工,应用前景十分广阔。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.
