In modern manufacturing, digital twins pose the promise of uniting the virtual process (models and simulations) with the physical process (measurement and actuation systems). Combining simulation models with real-time data may potentially be used to create a new type of high-fidelity model, and bring process monitoring and real-time control to a new level. In complex manufacturing processes, such as forming, it is however often nearly impossible to directly map real-time measurement data on physics-based models. This presentation will give an overview of the challenge. Furthermore, an approach will be presented to simultaneously estimate process variations and improve the underlying process model, for a mass manufacturing forming process.
