WebMar 28, 2024 · Abstract. In profile bending, the geometrical defect that reduces dimensional quality is mainly due to springback. While predicting dimensions after bending is important for quality control, many factors during bending cause difficulty in springback prediction. Furthermore, complex three-dimensional (3D) shapes in bending can make springback … WebStretch-forming based on loading at discrete points (SF-LDP) is a new stretch-forming process, by controlling the loading trajectory at each discrete point; the process can fulfill the sheet metal deformation along the prescribed forming path. In this paper, force-controlled SF-LDP process was proposed and discussed.
