Molecular Dynamics Analysis on Vibration Assisted Cutting : Effect of Vibration Parameters(M^4 processes and micro-manufacturing for science)

Abstract

This study aims to clarify the effectiveness and the mechanism of the application of vibration on the reduction of plastic flow and the improvement of machined surface in the micro/nano cutting or grinding processes. In this study, the molecular dynamics method has been applied to the analysis of extremely small amplitude and high-frequency vibration assisted cutting processes. In the simulations, the cutting tool and the workpiece are assumed to be rigid diamond and pure aluminum, respectively. In this paper, the effect of the vibration parameters, such as frequency and amplitude on the reduction of plastic flow and cutting forces was mainly clarified.
