Article Preview

Exit fracture, the main factor influencing the precision of workpiece, has already been extensively studied. In the case of nanometric cutting technology, the depth of cut is in the range of nanometer or sub-nanometer, there may be some different discipline dominating the exit fracture generation process. Molecular dynamics (MD) method, which is different from continuous mechanics, has already played an important role in describing microscopic world. The author carried out MD simulation of the micro-mechanism of exit fracture generation process, the results show that different types of burrs is generated depending upon materials ductility and the dimension of burrs may be increased with the increasing of depth of cut.
