Tool deflection in the milling of titanium alloy - case study

Tool deflection strongly influences on the workpiece quality. Author of the paper built a simulation model of the down milling process of titanium alloy (Ti6Al4V) with a tool made of sintered carbides. Material model consists of strain, strain rate and termal sensitivity formulations to predict the stress field distribution in the cutting zone. Numerical calculations were experimentally verified on the milling centre, equipped with measuring devices: force dynamometer, thermo-vision and high-speed video cameras.
