摘　　要：由于镗孔时一个尺寸的孔对应一把镗刀,每一个孔又经历从粗到精加工的过程,会造成镗刀数量的巨大,可以利用数控螺旋插补功能进行孔的精加工,螺旋插补轨迹对精度影响取决于螺旋升角λ。通过工艺参数优化,配合主程序+子程序可以实现深孔铣削,进一步优化刀路设计,结合宏程序的循环优势,提高编程效率。Because the hole of a size corresponding to a boring boring, every hole and undergo a process from coarse to fine processing, will cause a large number of boring, can carry out the finishing hole with CNC helical interpolation function, helical interpolation influence on precision depends on the helix angle λ. Through optimizing process parameters, with the main program and subroutines hole milling, and further optimize the tool path design, combined with the circular edge of macro program,improve the efficiency of programming.
