Summary:Springback remains as a challenge in the automotive stamping industry. Use of different new materials for lightweighting purposes like aluminium, HSS and AHSS increase studies on that subject. Moreover, constraint timings and cost reduction targets require robust strategies on springback prediction and its compensation. In this paper, the industrial approach to this issue is told through a successful large scale case study where various applied methods are mentioned for accurate springback prediction and effective compensation.On the prediction side, this includes hardening curve, yield criteria, FLC, friction, drawbeads, spacers, blankholder model, blank properties, thickness, material grade, clamping concepts, mesh parameters. On the compensation side, strategies are playing an important role and also certainly validation. For the validation, so called, full cycle simulations are performed. Full cycle simulations must be carefully evaluated due to many noise factors.
