Special Issue Information

Dear Colleagues,

The nature of manufacturing processes can occasionally be complex, as various localized or extensive phenomena, such as phase change, deformation and grain restructuring, occur simultaneously. The experimental observation of these phenomena, especially in bulk materials, is not trivial because of the high level of accuracy required and the inherent challenges encountered when attempting to visualise the atomistic structure of materials. Additionally, continuous models are based on constitutive equations that inherently contain assumptions about the evolution of a system over time. However, in recent decades the vast increase of computational power as well as the development of computational modelling techniques has made feasible the atomistic modelling of manufacturing processes, such as nanocutting, heat treatment and additive manufacturing, without making any ab ignition assumptions.

The goal of this Special Issue is the collection and presentation of state-of-the-art developments in the atomistic modelling of manufacturing processes. We seek research contributions related to atomistic/mesoscale/multiscale modelling of manufacturing and processes encompassing the following topics:

  • Material removal processes;
  • Solidification/annealing;
  • Indentation;
  • Laser ablation;
  • Additive manufacturing;
  • Material characterization;
  • Ion beam processing.

In this investigation, three-dimensional molecular dynamics simulations have been performed in order to investigate the effects of the workpiece subsurface temperature on various nanocutting process parameters including cutting forces, friction coefficient, as well as the distribution of temperature and equivalent Von Mises stress at the subsurface. The simulation domain consists of a tool with a negative rake angle made of diamond and a workpiece made of copper. The grinding speed was considered equal to 100 m/s, while the depth of cut was set to 2 nm. The obtained results suggest that the subsurface temperature significantly affects all of the aforementioned nanocutting process parameters. More specifically, it has been numerically validated that, for high subsurface temperature values, thermal softening becomes dominant and this results in the reduction of the cutting forces. Finally, the dependency of local properties of the workpiece material, such as thermal conductivity and residual stresses on the subsurface temperature has been captured using numerical simulations for the first time to the authors’ best knowledge.
