Numerical Modeling of Titanium Alloy Ti10V2Fe3Al Milling Process

The simulation of material machining using finite element models is a powerful tool for the optimization simulated processes and tools, as well determination cutting process characteristics that are difficult or practically impossible to determine by experiment. paper presents results numerical titanium alloy Ti10V2Fe3Al (Ti-1023). behavior machined was modeled with Johnson–Cook constitutive equation, its damage mechanism Cockcroft Latham model. parameters equation were determined DOE sensitivity analysis during orthogonal cutting. values force components, minimum maximum chip thicknesses, used target functions analysis. generalized fracture stress calculated set intersection individual multitude these parameters. studied showed an acceptable agreement experimental data when speed feed changed significantly. deviation in forces from their measured ranged about 10% 20%.
