Abstract: The possibility of controlling the bending angle in press V-bending using shot peening (SP) in the die was confirmed using aluminum alloy A5052 with 1 mm thickness. The bending radius and angle were 10 mm and 90°, respectively. After press bending, the bending angle is greater than 90°. By controlling air pressure and shot mass, the bending angle was reduced using SP. The reduction in bending angle using SP was greater when SP was performed during press loading than after unloading. Under the conditions of this experiment, the reduction in bending angle using SP was small for thicknesses of 2 mm or greater. Future experiments will be planned to use a direct-pressure system with a high shot velocity.
