Abstract

La présente invention se rapporte à un procédé et à un outil d'emboutissage d'un matériau en feuille. Selon l'invention, on procède à la mise en forme d'une feuille (2) d'épaisseur constante par emboutissage, et en fin de course d'emboutissage, on réalise sur une face extérieure de la feuille un raccordement d'un faible rayon en appliquant localement, sur la face intérieure de la feuille (2), une force contraignant la matière de la feuille emboutie à un plaquage côté extérieur.
