FE Analysis of One-Directional and Elliptical Vibration Cutting Processes

Processes of one-directional vibration cutting, elliptical vibration cutting and conventional cutting are modelled by using MSC-Marc FEM software in the present study. The vibration is assumed to be applied to a rigid cutting tool in the cutting direction for the one-directional vibration cutting and in the cutting and thrust directions for the elliptical vibration cutting. Then, the cutting forces and the stresses generated within the workpiece during the abovementioned processes are estimated by applying the developed FE model, and their cutting mechanics are discussed. Influence of various process parameters such as speed ratio, amplitudes and phase difference is subsequently investigated. The simulated results are also compared with some experimental data published in the literature.
