Abstract
Molecular dynamics simulation is carried out to study the nanometric machining of single crystal Nickel (Ni). Through an investigation of atomic displacement and the variation of cutting force, it is found that the latter is in accordance with the number variation of elastic displaced atoms in the workpiece. It is further found that the generation of complex stacking faults is the predominant cause of cutting force fluctuation, and the stacking faults with complex structures lead to work-hardening. The temperature of the cutting tool and workpiece is studied during the machining process. It is concluded that the selection of averaging steps has a significant influence on the system temperature distribution. Thus, the time-spatial averaging method, which has a high accuracy and consistency in temperature distribution, is proposed.
