Abstract

A method of research on the size effect of the specific cutting energy based on the numerical simulation has been proposed. The theoretical model of the research on size effect of specific cutting energy using single grit scratch simulation has been presented. A series of single grit scratch simulations with different scratch depths have been carried out to acquire different material removal rates. Then the specific cutting energy was calculated based on the power consumed by scratch process and the material removal rate. The relationship between the specific cutting energy and the material removal rate has been given which agrees well with that presented by Malkin. The simulation results have been analyzed further to explain the relationship between specific cutting energy and material removal rate.
