Numerical Analysis of Face Milling Ti6Al4V with Different Tool Materials

Abstract:

Ti6Al4V is one kind of difficult-to-machine aeronautical materials, which is generally machined by coated cemented carbide tools. A three-dimensional face milling model is developed in this paper with finite element analysis software AdvantEdge to analyze influences of tool materials on tool temperatures, cutting forces and tool stresses. The simulation results have shown that PCBN tools are the most appropriate for machining titanium alloy when it is machined with heavier cutting parameters. Cemented carbide-K tools and PCD tools are suitable for finish machining titanium alloy. The PCD tools are superior to cemented carbides-K under the same machining conditions. Nature diamond cutting tools are incompatibility to machine titanium alloy due to their higher costs and carbonization at high temperature. In the view of cutting forces and distributions of tool stresses, nature diamond tools are optimal and the cemented carbides-K are the poorest in machinability rate at the same cutting conditions, while super-hard tools gets longer tool life.
