Phénomènes dynamiques en usinage : Prédiction de l’état géométrique des surfaces usinées
Communication sans acte
Date
2013Résumé
Présentation concernant la modélisation des phénomènes dynamiques en usinage. Cette modélisation a pour particularité de permettre la prédiction de la géométrie des surfaces usinées (défauts de forme, d'ondulation) que la pièce soit considérée comme rigide ou flexible.

A general method to accurately simulate material removal in virtual machining of flexible workpieces Rapport de rechercheMulti-axis milling and other computer numerical control machining processes allow us to create very complex geometries and thin parts. In this context, virtual machining is a powerful tool, but the simultaneous vibrations ...

Communication avec acteGERASIMENKO, Artem; DUCHEMIN, Jérôme; GOUSKOV, Alexander; LORONG, Philippe; GUSKOV, Mikhail (ELSEVIER, 2015)Thin tubular parts are often subject to turning process during manufacturing. The increasing compliance of the workpiece, which is associated to tool displacement and to matter removal, can give rise to chatter, leading ...
