Dynamic behaviour of -Ti-15333 in ultrasonically assisted turning: Experimental and numerical analysis

The enhanced strength, fatigue life, and corrosion resistance properties of Tialloys have attracted many industries for their utilization in various components exposed to extreme operating conditions. The machining of these alloys using conventional machining techniques is one of the main challenges in its wide application in many components, and there is an obvious demand to analyse the materialsʹ response to these alloys in machining processes by developing simulation-based models. The materialsʹ behaviour used in simulation of machining processes is usually determined by means of Split-Hopkinson- Pressure-Bar (SHPB) setup. A 3D thermo-mechanically coupled Finite-Element (FE) model of SHPB is developed in the current work to analyse materials response of -Ti-15333 at the selected temperature, strain rate, and strain. The obtained materialsʹ response to the tested alloys is used in 3D thermo-mechanically coupled FE model of ultrasonically assisted turning and conventional turning at various tested cutting conditions. The developed FE model is used for parametric analysis of -Ti-15333 machining, and the obtained FE results are in good agreement with experimental results.
