| Abstract: | This paper establishes the flexible milling force model of ball-end mill.In this paper,influence mechanism of variously physical factors for milling force in any feed direction is studied during the milling process.Firstly,the effects of spindle eccentricity,cutter deflection and cutter vibration for the instantaneously undeformed cutting thickness are analyzed,and the mathematical expressions of chip thickness is set up.Then,on this basis of cutting force and chip load,the milling force model of ball-end mill with considering integrated physical factors is established and a simulation system for prediction of milling forces during the milling process is developed.This milling force model is verified through simulation and analysis of milling forces. |
