摘　　要：对复杂深孔内螺旋曲面进行高精度和高效率加工是复杂深孔加工领域研究的热点问题之一。针对深孔内螺旋曲面加工尚需解决的关键技术建立一种通用的螺旋曲面线型数学模型,为刀具精确设计提供理论计算依据。提出了深孔内螺旋曲面拉削加工方案并进行了拉刀的三维建模,分析论述的复杂深孔内螺旋曲面拉刀设计流程和实例对于成套拉刀设计有参考指导意义。High machining quality and high efficiency requirements of helical grooves is one of the hot issues of complex deep - hole processing field. According to key technologies of machining complex deep - hole helical groove to be solved, the mathematical model of helical groove linear is established, which is the theoretical basis for the precise broach design, and broaching schedule of deep - hole helical groove is provided, and then 3D models of broaches are established. Finally, analysis of the discussed broach design procedure of complex deep - hole helical groove and an example are given, which offer references for designs of complete sets of broaches.
