Analysis of Influence of Installation Error between Installation Hole of Forming Milling Cutter and Cutter Bar on Screw Rotor Profile
There are various errors affecting the machining accuracy of the rotor profile in the process of rotor machi-ning.At present,many studies have analyzed the influence of the adjustment error of the center distance and the installation angle on the rotor machining.However,the influence of the installation error caused by the gap between the installation hole of the milling cutter and the cutter bar of the screw milling machine on the rotor profile is need to study.The installation er-ror can be expressed as the eccentricity between the geometric axis and the rotary axis of the cutter head,the deflection be-tween the two axes,and the coupling of eccentricity and deflection.This paper studies the influence of three forms of instal-lation errors on the rotor profile and the influence size,and it study has certain guiding significance for the accuracy analysis and error control of the rotor profile.
