This study investigated die geometries on the ultrasonic assisted micro forming process. Using experiment design method, some geometry features of the die are defined, such as different diameters of the hole and grooves. The study not only applied metal forming theory to assign process parameters, but also discussed how die geometries influence modal parameters of the ultrasonic vibration system by modal analysis. The results verified the accuracy of modal analysis and proved that applying ultrasonic on micro forming could raise the efficiency of the process by analyzing relations between die geometries and forming results. The achievements would help the application of metal materials on precision machining and provide corporations the process parameters to research and develop the ultrasonic assisted micro forming process.
