Ultrasonic vibration cutting processes are modeled and simulated in the present research, utilizing MSC-Marc FEM software. The vibration is applied to the cutting tool in one or two directions denoted by vibration cutting (VC) and elliptical vibration cutting (EVC), respectively. The cutting forces and the stresses developed within the workpiece during the vibration cutting processes are estimated and compared with those in the conventional cutting (CC) process. The influence of various parameters such as speed ratio and amplitude are subsequently investigated. It is partially concluded that though the cutting force fluctuates periodically in VC and EVC, its average value changes from CC to VC and EVC in descending order. The cutting force decreases with a rise in the speed ratio in EVC and does not change in VC.
