Finite element modeling of ultrasonic-assisted turning: cutting force and heat generation

The outstanding characteristics of titanium alloy (Ti–6Al–4V) have made this material applicable in aerospace and medical components. However, due to its poor machinability characteristics, researchers are forced to understand the machinability behavior of Ti–6Al–4V. In this paper, [Formula: see text] orthogonal array-based three-dimensional finite element modeling for the cutting force and chip formation analysis during the machining of Ti–6Al–4V using cubic boron nitride tool in dry turning environment has been investigated. The finite element simulation was performed using ANSYS Workbench, version 19.0. Cutting force and chip formation were investigated using the results obtained from [Formula: see text] orthogonal array-based three-dimensional finite element modeling. This research would help to identify the optimum cutting conditions and minimize the cutting force followed by analyzing the types of chips formed during machining under the selected set of cutting conditions.

Simulation Results

The improvement in machinability during thermally assisted turning of the Ti-6Al-4V alloy has been investigated using finite element modeling. A 2D thermally assisted turning model was developed and validated by comparing the simulation results with experimental results. The effect of workpiece temperature on the cutting force and chip formation process was examined. The predicted cutting forces and chip morphologies from the simulation strongly correlated with the experimental results. It was observed from the simulation that the chip forms after the coalescence of two deformed regions in the shear band and that the cyclic cutting forces are strongly related to this chip formation process.
