Prediction Of Three Dimensional Milling Forces Based On Finite Element Method For Up Milling Process Of Titanium Alloy (TI-6AL-4V)
The model of milling force is mainly proposed to predict and analyze the cutting process based on finite element
method in this paper. Firstly, Milling Finite Element model is given based on orthogonal cutting principle, and then the
influence laws of cutting parameters on chip formation are analyzed by using different simulation parameters. In addition, the
three-dimensional milling forces are obtained from finite element models. Finally, the values of milling force by the milling
experiment are also compared and analyzed with the simulation values to verify the feasibility and reasonability. It can be
shown that milling forces match well between simulation and experiment results, which can provide many good basic data and
analysis methods to optimize the machining parameters, reduce tool wear, and improve the workpiece surface roughness and
adapt to the programming strategy of high speed machining.
