Abstract

L'invention concerne la réalisation de profil de filetage, d'abord sur une pièce cylindrique, via une première série de filières de filetage, le métal s'écoulant librement dans les rainures de la première série pour donner une crête arrondie (ou autre). Puis le filetage est retravaillé dans une seconde série de filières à profondeur de rainurage réduite, ce qui permet de reformer et de ré-aplatir la crête arrondie. On peut aussi former un profil de filetage sur une pièce cylindrique par une première série de filières à surfaces contenant deux ou plus de deux formes de rainures distinctes. Des rainures découpées en diagonale rencontrées par la pièce auraient une forme sensiblement identique à un profil de rainure de filière « normal », selon une profondeur D + H. Des rainures en contact avec la pièce telle qu'elle sort de la filière auraient une forme à profondeur de rainure réduite environ équivalente à « D »
