中文摘要：
纳米磨削是实现超精密加工的重要方法，纳米磨削能产生极其薄的切屑，实验证明纳米磨削的切屑厚度可以下降到1nm。因此可以使用分子动力学仿真来分析纳米磨削机理。运用Gear预测修正算法对磨粒原子和工件原子之间的相互作用进行了研究。建立了分子动力学仿真的运动方程，对其进行了数值求解，从而获得了工件原子变化后的位移和速度。
英文摘要：
Nanometer grinding is the important methods of achieving the super-precision machining. The extremely thin chips can be produced by nanometer grinding. The experimental showed that the very fine chips can be down to 1nm. Therefore molecular dynamics computer simulation can be used to analyze the mechanism of nanometer grinding. The subject which deals with the interaction between the grinding grain particles and workpiece particles was studied by the method of Gear＇s predictor-corrector algorithms. The equation of motion was built up, and solved by numerical method. Then the speed and displacement of these particles were obtained.
