Using open-die cold extrusion technology instead of traditional cutting to form the electromotor shaft shoulder fillet is presented. In comparison with cutting methods used in industrial application, open-die cold extrusion has many advantages such as minimum material waste, high dimensional accuracy, reduction or complete elimination of machining, good surface finish, better mechanical properties of products than those of the original material due to favorable grain flow. The analysis on the two forming for the electromotor shaft shoulder, including one-step approach and two-step approach, is carried out. Numerical simulation and experimental investigation on it is performed and the different application ranges of the two methods are achieved.
