【 摘 要 】

Face milling is considered as one of the most important methods in order to produce parts with high quality surfaces and considerable dimensional accuracy in a relatively short time. Investigation of the effect of process parameters on the outcome of this process is usually conducted experimentally or computationally by soft computing or numerical methods. However, when it is desired to study face milling in the nanoscale, experimental cost can be extremely high and numerical methods such as the Finite Element Method is unable to be employed, as it is a method mainly suited for continuum mechanics. Thus, a method such as Molecular Dynamics can be used to perform simulations of face milling in the nanoscale. In this work, cases with cutting tools with one and three cutters, moving at different feed values are considered and results concerning chip morphology and cutting forces are presented.
