### Abstract

Currently, most gear in the actuator are made by traditional methods such as bulk forming from block billet and then cutting for finishing. Such manufacturing methods often lead to material wastes due to cutting out of a large about 30% amount of excess processing. To save material and improve production efficiency, we can choose tube billet for bulk forming. However, when using bulk forming with tube billet, it should be calculated carefully to avoid being of instability and appearing of folding defects in workpiece. This article presents the research on forming process of the coupling detail using methods numerical simulation and based on obtained results to determine the suitable geometry of tube billet for the forming in closed die.
