Molecular dynamics simulation of nanometric grinding - The effect of crystal anisotropy on the quality of machined surface

In modem manufacturing, the quality and property of the product both depend on the precision engineering which is the key factor of advanced processing technology. The manufacturing mechanism is the foundation and essence of the manufacturing method. Being the utmost manufacturing technology, the precision and ultraprecision manufacturing involves the microscopic world and the structure of the materials, so it is of important theoretical significance and practical value to systematically study their machining mechanism and technology. Take the example of single crystal aluminum, this paper conducted molecular dynamics (MD) simulation of nanometric grinding, and also investigated the effect of crystal anisotropy on the integrity of the machined surface.
