Finite Element Technique for Predicting Stress Distribution in Milling TC4 Titanium Alloy

Abstract

Cutting forces modeling is the basis to understand, simulate milling process and further to control milling process parameters for obtaining higher precision workpieces. With the development of engineering technology, FEM can be used to simulate metal machining process and gain better understanding of material flow within dies, so as to optimize tooling to eliminate tears, laps and other forging defects. In this paper, the calculated cutting force increases approximately logarithmically with the cutting speed, as should be expected from the logarithmic rate dependence.
