“…During the vibration energy assistance in the machining process, the workpiece or the cutting tool is provided vibration for periodic engagement and disengagement between the two interacting surfaces. It is also known as a discontinuous or intermittent cutting process due to the periodic separation and significant improvement in the process performance has been described in the published literature [14]. Similarly, the assistance of thermal energy has been provided to the workpiece surface during the machining process.…”

The utilization of various energy sources to assist the machining process has become prominent to achieve substantial improvement in machining performance. These energy sources have also resulted in an alternative to cutting fluids which is safer for both the universe and human beings. The combined action of laser and ultrasonic vibration energies during the turning process has shown significant achievement in machining process capabilities. Therefore, an attempt has been made to provide ultrasonic vibration in the radial direction and laser to preheat aluminium 3003 alloy simultaneously during the ultrasonic-vibration-laser assisted turning (UVLAT) process. Machining performance has been analyzed in terms of machining forces, machining temperature, chip morphology, surface damage, and surface roughness. A comparative machining performance analysis has been carried out among the conventional turning (CT), laser assisted turning (LAT), ultrasonic vibration assisted turning (UVAT), and UVLAT processes. The outcomes of the current study indicate significant benefits of the UVLAT process on the machining performance of aluminium 3003 alloy. However, surface damage and surface roughness have been affected negatively during the UVLAT process due to the pin-point hammering and particle adhesion on the workpiece part. Hence, the selection of vibration direction is a critical factor during the vibration machining processes.
