摘要：对国标GB、德国V63、V70麻花钻沟型螺旋面进行分析，分别建立了数学模型进行精确三维建模。根据空间交错轴齿轮啮合原理，采用无瞬心包络法对关键工装成型铣刀（成型砂轮）进行设计计算，利用计算机图形学进行加工仿真。分别从应用、设计、加工三方面进行对比，有助于德国V63、V70麻花钻的推广应用和研究改进。

Abstract:The Chinese national standard GB，German V63，V70 twist drill groove spiral surface are studied，and the mathematical models are established respectively.According to the principle of spatial staggered shaft gear meshing，the key tooling forming cutter (formed grinding wheel) is designed and calculated by noinstantaneous envelope method，and the machining simulation is carried out by computer graphics.Comparing them from application，design and processing，a clearly understanding of their respective characteristics is put forward.The promotion and application of German V63，V70 twist drill，research and improvement are contributed.
