英文摘要：

With the basic principle of energy distribution in super high machining, the relation between machining velocity with residual stress could be concluded. The model in super-high point-grinding was transformed into the geometrical model used in machining with per abrasive grain. A simulation model using explicit finite element Abaqus was developed to investigate the residual stress＇ s distribution in a machined layer while different machining velocity and different depth in machined surface, which provide the theory to achieve high precision machining in super-high point-grinding.
