Magnetorheological Finishing（ MRF） facilities generally vary in axis configuration and axes＇ joint motion types,thus a universal space-determined generation method for MRF spot is proposed in this paper to tackle the issue involving the transplant of control system among various application situations. First,representation method of single part＇s motion is explored,hence establishing the analysis method of multipart＇s motion. Furthermore,the Lower Body Theory is utilized to construct the governing equation of universal space-determined spot generation,which is beneficial in implementation of the computation process in computers. Finally,the proposed method is verified through simulation and experiment. The proposed method provides the basis for engineering of universal analysis system of flexible finishing.
