Springback, which occurs during stamping of shallow-drawn titanium alloy sheets, can negatively influence the stamping accuracy and reliability of follow-up assembly and welding of parts and restrict the application of titanium alloy sheets when high precision is a requirement. Therefore, accurate prediction and control of springback in titanium alloy sheets is an industrial problem that requires urgent attention. In this paper, a TA2M titanium alloy box formed via shallow drawing is used as the research object and springback control during stamping is attempted by varying the magnitude and mode of the blank holder force (VBHF) and height of a controllable drawbead. The influences of drawbead height, VBHF magnitude, and loading mode on the resulting sheet springback are determined by means of finite element simulation and experimentation to determine the best combination yielding the minimum springback. The results of this research provide a reliable reference for future efforts to form tough materials.
