  • Compressive stress forming systems and methods
    Patent number: 12691486
    Abstract: The present disclosure relates to forming a metallic part to decrease residual stress and reduce springback behavior in the metallic part after forming. Target locations in the metallic part for excess material are determined based on electronic modelling prior to forming. The excess material in the target locations is configured to decrease residual stress in the metallic part after forming. The metallic part is contacted for forming at one or more contact locations away from as-cut end surfaces of the metallic part, such that the as-cut end surfaces are unconstrained during forming. The excess material is caused, based on the one or more contact locations and the excess material at the one or more target locations, to flow in one or more specific directions during forming to decrease the residual stress in the metallic part and reduce springback behavior in the metallic part after forming.
