Steet metal forming analysis with multipoint reconfigurable die using data mining technique

Résumé

A very important parameter to evaluate the quality of the deep-drawed complex parts is the springback. Using reconfigurable multipoint dies this parameter can be controlled by pins positions during the process. It result the necessity to have information in order to act very quickly in this direction. This paper goal is to dermine the rules type pins position-material response (sringback) in order to assure dimensional precision of the deep-drawed complex parts. The method to obtain this rules consist in: i). FE simulation of different schemas of the dies and different materials; ii). extraction of the input-output parameters in order to create the data base; iii). determination of the rules using the data mining technique.
