A framework of physical simulation system for the prediction of machined surface roughness is presented based on the analysis of masons generated surface roughness in NC machining, and the cutting force model, vibration model in cutting process and surface roughness model are constructed. As a result, the theoretic foundation is offered for the prediction of machined surface roughness by the physical simulation.
