Micro Machining Simulation Analysis by Finite Element Method

Article Preview

Abstract:

Micro machining becomes more and more important with the tendency of miniaturization of components used in various fields from military to civilian applications. The finite element method software Abaqus is used to model the nonlinear thermal force coupled elastic-plastic micro machining processes. Relatively systematic simulation analysis has been introduced based on the model combining the Johnson-Cook failure criteria, element deletion strategy etc. It reveals that the size effect is dominant while the depth of cut reaches the cutting edge radius. The rake angle plays more important roles on the micro machining than that of the cutting speed.
