The method for simulating bending of a tube by means of at least one bending machine comprising a step for calculating at least one cycle of bending commands (30, 35) linked with at least one tube manufacturing parameter according to a tube data set (10) and to a technological data set (20). At least one three-dimensional geometric model (40) of at least one bending machine and of associated mechanical tools is obtained according to at least one parameter (50) from the cycle of calculated bending commands (30, 35). According to the cycle of calculated bending commands (35), a three- dimensional and kinematic simulation of the bending process of the tube represented by the tube data set (10) is obtained by means of at least one bending machine and of associated mechanical tools represented by the corresponding three-dimensional geometric model (40). The possibility of manufacturing the tube by means of at least one bending machine and of associated mechanical tools during the three-dimensional and cinematic simulation obtained thereby is verified.

Le procédé de simulation de cintrage d'un tube au moyen d'au moins une machine de cintrage, comprend une étape de calcul d'au moins un cycle de commandes de cintrage (30, 35) liées au moins à un paramètre de fabrication du tube en fonction d'un jeu de données tube (10) et d'un jeu de données technologiques (20). On obtient au moins un modèle géométrique tridimensionnel (40) d'au moins une machine de cintrage et d'outils mécaniques associés en fonction d'au moins un paramètre (50) issu du cycle de commandes de cintrage ainsi calculées (30, 35). Selon le cycle de commandes de cintrage ainsi calculées (35), obtenir une simulation tridimensionnelle et cinématique du processus de cintrage du tube ainsi représenté par le jeu de données tube (10) au moyen d'au moins une machine de cintrage et d'outils mécaniques associés ainsi représentés par le modèle géométrique tridimensionnel correspondant (40). On vérifie la possibilité de fabriquer le tube au moyen d'au moins une machine de cintrage et d'outils mécaniques associés lors de la simulation tridimensionnelle et cinématique ainsi obtenue.
