The demand from the automotive industry for increasingly complex sheet metal components has led to the common integration of sensors and control-systems in the sheet metal forming process. However, control-systems currently implemented in the metal forming process only monitor and control the state of the equipment used in the process, often lacking the ability to incorporate the work-piece in the closed-loop control. Furthermore, traditional control strategies are not equipped to model the complex non-linear behavior of sheet metal under transient forming conditions. FEM models can accurately model the behavior of sheet metal but are too computationally-expensive to incorporate in an inline-control system. Digital Twins can solve this issue by constructing a probabilistic framework for the data generated from FE simulations to reduce the computational complexity of the model. The goal of this work is to develop a Digital Twin of a progressive die for the implementation of a closed-loop control by using a dataset of FE models previously constructed in a DOE. The constructed Digital Twin will be validated against FE models that were not used in its construction.
