| Abstract: | Multi-point forming is a flexible forming method of sheet metal, which employs two reconfigurable elements groups instead of conventional male and female dies to form 3D sheet metal parts. In the paper, a multi-point rapid forming system driven by CAD models and self-made laser scanning measurement machine for 3D sh eet metal parts were developed. The multi-point closed-loop forming method was proposed. Under the control of a proportional-integral-derivative algorithm, the closed-loop forming experiments were performed and the curved surface error of the formed part was small. |
