Modeling techniques in nanofinishing processes - a review

With the growing demand of high surface finish components, the need of nanofinishing techniques arises immensely. Generally, finishing experiments are performed to analyse the surface finish, temperature rise, and material removal. Using modeling techniques, one can analyse the same without carrying out experiments for different nanofinishing processes. These techniques help in finding different unexpected situations before initiating any finishing process. Using the methods of computational fluid dynamics (CFD), finite element method (FEM), molecular dynamics simulation, and mechanistic techniques it becomes easy to predict material removal, heat generation using the results of velocity, pressure, stress, and temperature. Modeling techniques offer fluid flow behavior, workpiece behavior visualizations under the effect of forces, cost-effectiveness solutions, and identification of problematic issues. In this article, a comprehensive review of different modeling techniques is presented for better understanding and visualization of the nanofinishing process. This review paper attempts to provide an informative literature survey on the research being done to simplify the understanding of modeling techniques and which modeling technique should be selected along with suitable modeling parameters considered by researchers for a particular nanofinishing process.
