Abstract:Product improvement and cost saving have always been important goals in the metal forming
industry. Numerical optimisation can help to achieve these goals, but optimisation with a deterministic
approach will often lead to critical process settings, such that the slightest variation in e.g. material behaviour
will result in violation of constraints. To avoid a high scrap ratio, process robustness must be considered in the
optimisation model. Optimising for robustness includes Robust Manufacturing (RM) techniques, Optimisation
Under Uncertainty (OUU) methods and Finite Element (FEM) simulations of the processes. In this paper,
we review RM and OUU. Subsequently, the combination of Statistical Process Control (SPC), robust and
reliability based optimisation methods, and FEM-based process simulation implemented in AutoForm-Sigma
is presented. An automotive deep drawing application demonstrates the potential of strategies that optimise
towards robust metal forming processes.
