英文摘要：
International application situation of the molecular dynamics simulation technology in nanometer machining is introduced in detail. Potential function of molecular dynamics simulation of ultra - high speed nanometer grinding mono - crystalline copper and mono - crystalline aluminum is selected properly. Experiments of nanometer grinding molecular dynamics simulation are made out. Results of simulation are analyzed and researched. Ultimate surface roughness obtained by molecular dynamics simulation of ultra -high speed nanometer grinding mono- crystalline copper and mono -crystalline aluminum is confirmed. The ultimate depth of deformed layer and the ultimate machining precision are forecasted for ultra -high speed nanometer grinding mono- crystalline copper.
