Abstract: In this paper, we point out several problems on fluid mechanics existing in the abrasive flow finishing, and study the dynamic simulations methods in the area. A case study is conducted on the process of free abrasive flow finishing, where we complete the dynamic simulations on the kinematic characteristics by a model of two-phase fluid. It is shown that the theory of two-phase fluid can practically direct the design of polishing machine, and the selection as well as the optimization of parameters for polishing technique.

Abstract: The flowing behavior on abrasive grains was analyzed by two-phase flow dynamic model when using different duty parameter in planetary lapping. The results show that the duty parameter will affect and control grains flowing behavior in lapping process. Further, it is pointed out that duty parameter is important to enhance productivity. The parameters of design and technology can be optimized economically and efficiently with the method so as to improve working quality.
