The Study on the Nanocutting by Rigid Body Tool at the Gas Environment Using Molecular Dynamics Simulations

This study successfully simulated the single crystal copper nanocutting with a rigid body tool at the nitrogen gas environment using molecular dynamics, and analyzed the workpiece stress distribution and dislocation during nanocutting. After simulations, a diamond rigid tool with a completely sharp produce a shear plane during cutting. The distribution of equivalent stress was greatest at the shear zone and that residual stress occurred on the machined surface. And the stress gets smaller as the distance from the chip surface is farther.
