In response to the problems of low efficiency and low surface roughness in traditional manual or software programming for milling taper holes,this paper explores the method of using macro programs to adopt the programming idea of spiral interpolation for milling taper holes(cylindrical holes)to improve processing efficiency.The macro program has strong universality,which can be used for milling conical holes and cylindrical holes.It can choose any type or size of milling cutter,as well as forward and reverse milling,and also it can choose various cutting parameters including rough and fine milling during machining.All of these can be assigned variables in the general macro program of this framework and then milled in one go.Through practical machining verification on FANUC CNC milling machine,the reliability of the macro program machining scheme is verified,and the surface machining quality and surface roughness of the conical hole are well controlled.This programming method can be applied universally to conical and cylindrical holes at any angle,and offers practical guidance in production.
