Systematic errors introduced by springback phenomena in metal-sheet stamping ask for part-process adaptations, involving blanks, die features, and process parameters. Springback simulations for a couple of common parts are presented, and the long trials for setting up realistic simulations are pointed out. A data-driven methodology is then suggested, based upon the combined use of FEM and Artificial Neural Networks (ANN) analyses. A test is given for a simple shaped part: starting from a small set of reliable simulated results, an ANN is trained and adopted to retrieve the springback distorted profile for different combinations of parameter values.
