Abstract

L'invention concerne un procédé de découpe d'une zone de bord annulaire (2) d'un corps creux (1) cylindrique à parois minces, notamment d'un corps creux (1) embouti en forme de coupe. On fait tourner le corps creux (1) cylindrique autour de son axe de cylindre (4) et, pendant ses multiples rotations, on dirige un rayon laser sur l'emplacement de découpe jusqu'à ce que la zone de bord (2) se détache du reste du corps creux.
