Driving as an incremental forming method can create almost any 2D and 3D sheet metal parts using universal tool sets. In this paper, stretching as an approach of the driving is modelled through the three phases that are the hybrid deformations, the material flows and the springback. In comparison with the experiment results, the stretching model is acceptable to be employed in the model predictive control that can supply the optimal control input through minimizing the objective function. The optimization problem is solved by the use of the discrete dynamic programming. The optimal control input results from the optimal path with minimal costs. The according parameters that can affect the control output are tuned to find out a reasonable combination of them that yields rational control outputs.      «
