The Nanocutting by Rigid/Elastic Tools with Nose Radius at the Gas Environment Using Molecular Dynamics Simulations

Abstract

.This study successfully simulated the single crystal copper nanocutting by a rigid body /elastic tools with nose radius at the nitrogen gas environment using molecular dynamics, and analyzed the workpiece temperature distribution and dislocation during nanocutting. After simulations, it can be found that when cutting with the elastic body tool, the tool itself was still distorted slightly, however, the cutting results of the elastic tool and the rigid body tool of the tool are not the same. The chip temperature was highest near the central rake and nose.The workpiece temperature when the elastic body tool cutting was lower; the temperature in the nose and rake plane is the highest, the more away from the nose, the lower the temperature.

Nano Technology: Molecular Simulation

“…Komanduri [9] also investigated the effect of tool geometry with tools of different edge radii relative to the depth of cut in nano metre. Lin and Huang [10] uses a method that combines molecular dynamics with finite element deformation model (MDFM) to calculate the stress and strain of single crystal copper that occur during nano-scale orthogonal cutting. They find that it has only minor influence for the different cutting speeds on the distribution of the strain and stress at the contact area between the cutting chip and rigid tool during steady cutting state.…”
