N2 - Several modern engineering materials are difficult to process with conventional machining methods. Ultrasonically assisted turning (UAT) is a novel machining technique, where high frequency vibration is superimposed on the cutting tool. Compared to conventional turning (CT), it demonstrated a range of benefits in processing many intractable materials. A decrease in the average cutting force, an improvement in the surface finish and noise reduction were observed. In this study a Lagrangian smoothed particle hydrodynamics (SPH) was introduced for the modeling of the vibro-assisted turning of this advanced alloy. The UAT was implemented into the model by using the user interface VUAMP, available in ABAQUS/Explicit. The model was validated with experimental data available in the literature. The influence of vibration parameters (i.e. amplitude and frequency) on the process variables such as cutting force, chip morphology, distribution of stresses and temperatures in the workpiece was investigated thoroughly.
