Design and Realization of helical rotor NC automatic programming system

摘要

Helical rotor is a core component of helical-lobe compressor. In this paper analysis is made on the geometrical properties of tooth curves, and rotor surface is processed by using standard spherical milling cutter on 4-axis numerical control machine with normal migration method. Based on the generation characteristics of helical rotor surface, object-oriented design method is used in this paper to achieve automatic programming system design for helical rotor. The calculation of helical rotor end face profile lines and cutter location point are realized, and over cutting analysis is carried out to generate high efficient numerical control processing program.
