Abstract

Apr\`es avoir d\'etaill\'e les principales difficult\'es li\'ees \`a l'usinage 5 axes UGV, nous pr\'esentons un mod\`ele de repr\'esentation des trajectoires 5 axes sous forme surfacique permettant de prendre en compte des contraintes g\'eom\'etriques et cin\'ematiques. Ce mod\`ele est int\'egr\'e dans d'optimisation des trajets 5 axes afin de maximiser la productivit\'e tout en garantissant la qualit\'e g\'eom\'etrique attendue. Un cas d'application est d\'etaill\'e, illustrant la modification de l'orientation de l'axe de l'outil afin d'am\'eliorer le comportement cin\'ematique des axes lors du suivi des trajectoires. After presenting the main difficulties related to machining 5 axes machining within the context of HSM, we present a surface model of 5-axis trajectories allowing taking into account geometrical and kinematical constraints. This model is integrated in an optimization scheme in order to maximize the productivity while ensuring the expected geometrical quality. A case of application is detailed, illustrating the modification of the tool axis in order to improve axis kinematical behavior during the tool path follow-up.
