The Influence of Tool Stiffness on the Dimensional Accuracy in Titanium Alloy Milling

Abstract

The paper presents the simulation model of down milling process of titanium alloy (Ti6Al4V) with a tool made of sintered carbides, considering a tool stiffness. A finite element method, applied for numerical computations was experimentally verified with the help of force dynamometer, thermo-vision and high-speed video cameras. Differences between measured and simulated values were less than 22 % for cutting forces and about 8% for maximum cutting zone temperature and about 5% for tool deflection in the active part of the cutting edge.
