【摘要】 超精密加工的快速发展涌现出许多传统加工理论无法解释的切削现象，因此，总结并提出新的超精密加工理论将会促进超精密切削加工的进一步发展。综述了经典切削模型、剪切塑性变形模型、切削能量耗散模型、纳米尺度切削模型等超精密切削理论模型，详细分析了影响超精密切削理论的材料学等因素，揭示了超精密切削加工在微纳观尺度下材料去除的本质过程。在此基础上，系统剖析了超精密加工切削力以及预测方法，为超精密切削加工的新工艺、新理论及新机理提供理论基础。更多还原

【Abstract】 The rapid development of ultraprecision machining raises many cutting phenomena that cannot be explained by the traditional machining theory. Therefore,it is necessary to summarized and propose new ultraprecision machining theory to promote the further development of ultraprecision machining. This study reviewed the classic cutting model,shear plastic deformation model,cutting energy dissipation model,nano-scale cutting model and other ultraprecision cutting theoretical models. It also concluded the factors including material and tool affecting the ultraprecision cutting theory,and revealed that the essential process of material removal at the micro-nano scale in ultraprecision cutting process. On the basis,systematic analysis of cutting forces and prediction methods for ultra-precision machining. It provides the theoretical basis of new technology,new theory and new mechanism for ultraprecision machining.更多还原
