s:The theory and implementation technology of DFM (design for manufacture) are discussed in this paper. Firstly, as the base of DFM, PME (product manufacturability evaluation) should be constructed according to the practical situation of enterprise and dynamic factors in the process of R&D. Secondly, several application mode of DFM are enumerated and their characteristics and applicability are compared. Finally, a practical method of evaluating the machinability of 3D model in early design stage is introduced. The practice indicate that the DFM system corresponding to practical enterprise environment can both check the error in design stage and inform the difficulties of machining to the later course of product development based on results retrieved from the evaluation process. With the help of this DFM system, the efficiency of global product development can be improved.
