In the present thesis, a description of the method of Molecular Dynamics for copper nano-grinding simulations at the nanoscale is presented and quality assessment of the results of the simulations compared to other studies and experiments is performed. In Chapter 1, a brief introduction of the characteristics of the Molecular Dynamics method is conducted. In Chapter 2, a description of the theory of Molecular Dynamics and its characteristics, showing a thorough study of the kinds of atoms who take part in the simulation of the potential energy and of the integration methods that can be used is conducted. In Chapter 3, the development of a code in Matlab is described, and the additions and amendments made to it in order to achieve an effective copper nano-grinding simulation with two diamond abrasive grains are presented. In Chapter 4, the results of simulations for different cutting conditions and the study of the influence of cutting parameters on cutting forces and chip formation are presented. The development of the material removal process, the temperatures and forces for different cutting depths, changes in the speed and geometry and tool wear of the cutting tool is studied. Results of the simulations are presented collectively. Finally, in Chapter 5, some general conclusions based on the simulations carried out are presented and some improvements that could be achieved for further study and research are proposed. |
