Abstract

La présente invention concerne un procédé de fabrication de produit en matériau en plaque permettant d'atteindre un faible coût de fonctionnement et, même pour des matériaux en plaque épais pour lesquels un usinage avec un chalumeau incliné a jusqu'ici été impossible en raison de limitations imposées à des machines de traitement de matériau en plaque en termes des épaisseurs maximales des plaques à découper, la découpe peut être effectuée de manière oblique par rapport à la direction de l'épaisseur d'un matériau en plaque. La présente invention concerne également une machine de traitement de matériau en plaque qui utilise ce procédé de fabrication pour fabriquer des produits en matériau en plaque. Suite à une étape de découpe au cours de laquelle une découpe en I est réalisée dans un matériau en plaque dans la machine de traitement de matériau en plaque, une étape d'élimination est mise en œuvre pour éliminer le matériau résiduel généré lorsque la découpe en I est réalisée. Après l'élimination du matériau résiduel, une étape de découpe inclinée est mise en œuvre, au cours de laquelle une découpe en V est réalisée dans le matériau en plaque avec un chalumeau incliné par rapport au matériau en plaque. De cette manière, un usinage incliné peut être effectué sur un matériau en plaque épaisse pour lequel un tel usinage était impossible en raison de limites dans les épaisseurs maximales des plaques à découper.
