A Study on the Bending Springback of Aluminum Alloy 5754

This paper describes an experimental work on the bending springback of aluminum alloy 5754. Experiments were performed using a 90° V-shaped matching die-punch combination, with and without clamping. Clamping was used to create tension during bending. The experimental parameters taken into account are the die radius, sheet clamping torque, sheet thickness and the level of cold work in the sheet.
