This paper describes methodology and FE tools developed to predict stresses and strains, able to evaluate in advance dimensional defects that normally arise during physical tools and process set up.
The integrated approach is based on the possibility to use FE tools and smart CAE procedures able to understand and transfer the results from one process step to the following one, taking into account the most relevant effects that mainly influence the final geometry. Within this approach Ls-Dyna can support the methodology with the needed flexibility.
The early prediction of dimensional defects and the possibility to evaluate in advance the effects of work processes on the final shape/ geometry of assembled components can address geometry modifications request and problems resolution before tools physical set up leading to high dimensional quality improvement.
