Multistep Incremental Forming beyond 100°
Abstract:
While Incremental Sheet Forming (ISF) is approaching accuracy levels suitable for industrial take-up for specific applications, limited forming angles are still a great concern, leaving many applications out of reach. In this paper a two sided strategy for multistep incremental forming is presented, aiming at increased uniform wall thickness. By sequentially forming steeper wall angles, alternating passes between front and back side of the sheet, wall angles up to 105.5° were successfully reached in AA3103 with a blank thickness of 1.5mm. A resulting minimal thickness of 0.4mm and thickness range of 0.2mm was achieved for the 105.5°part.
