Simulation of nanometric cutting using molecular dynamics

Sökning: L773:2212 8271 > Simulation of nanom...

The aim of this work is to perform molecular dynamic simulations of nanometric cutting on single crystal copper with a diamond tool in orderto investigate the dependence of crystallographic orientation and cutting speeds on the cutting forces, machined surface and temperature. It wasfound that the temperature in the substrate, locally and globally, increased for increasing velocity. A higher degree of surface roughness was foundfor the [1 1 0] orientation and the tendency to form a granular structure behind the tool was found for the [1 1 0] and [1 1 1] orientations. For thesame tool advancement, a longer and thinner chip is formed only for higher velocities, while no significant dierence was found for the cuttingforces.
