Phénomènes dynamiques en usinage : Prédiction de l’état géométrique des surfaces usinées
Communication sans acte
Date
2013Abstract
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.
