These strategies lead to the increasing importance of the forming method and types of materials used.
The reliability of what has been developed it has been demonstrated with a specific numerical-experimental activity which has helped to understand, for defined process conditions, which is the relationship between one of the most critic factor like it is the drawing depth and a given material and blank thickness.
Much more it has to be done in order to explore the process sensitivity versus other major factors like for example: different geometric variables for a given shape like for example fillets radius, or different material types.
