Machining impeller parts complex curved surface, the overall stiffness of the machine tool, tool position and orientation changes, the stiffness distribution of the workpiece will affect the processing system, thereby affecting the quality of the machined surface. In this paper, four-axis NC machining centers as a example, based on multi-body small deformation theory, through the point transfer matrix, the Jacobian matrix, etc. complete the system stiffness field modeling, and the introduction of three-dimensional force ellipsoid. under the different tool spatial gesture to establish an integrated processing system stiffness field, by force ellipsoid beam analysis tools, tool position and orientation of the tool, the tool spindle with the department, blades, etc. for stiffness performance impact of the system, analysis of the distribution of the stiffness characteristics of the blade surface. Finally, experiments show that the theoretical model can effectively optimize the impeller blades processes.
