Various kinds of micro-cutting simulations based on molecular dynamics (MD) have been proposed in which the temperatures of the outer boundary were assumed to be steady states. Considering both heat and force boundary conditions is necessary in the MD simulations for the limited size of the model. To investigate the influence of the size of the model on behaviors of the workpiece, two dimensional cutting MD simulations for copper single-crystals are carried out using four kinds of models in which the restricted boundary of different sizes and the unsteady heat boundary are included. It was obtained that the boundary conditions exert the influence on both sub-surface damage and the temperature distributions in the workpiece when the boundary is close to the tool edge. Appropriate temperature distributions in the workpiece near the boundary are exhibited to provide the heat conditions at the boundary.
