Abstract
The aim of this work is to perform molecular dynamic simulations of nanometric cutting on single crystal copper with a diamond tool in order
to investigate the dependence of crystallographic orientation and cutting speeds on the cutting forces, machined surface and temperature. It was
found that the temperature in the substrate, locally and globally, increased for increasing velocity. A higher degree of surface roughness was found
for 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 the
same tool advancement, a longer and thinner chip is formed only for higher velocities, while no significant dierence was found for the... (More)
