Impact of Continuous Scanning Speed Variation on Microstructure in LMP-DED Additive Manufacturing

This paper deals with additive manufacturing, which enables parts with complex geometries to be produced layer by layer. For specific geometries, such as bent parts, it is necessary to vary the bead size within or between layers by modifying process…

Génération de trajectoires en fabrication additive par projection de poudre pour contrôler la géométrie et la microstructure

La fabrication additive est devenue un procédé très répandu ces dernières années en raison de sa capacité à produire des pièces de formes complexes. Cependant, malgré son utilisation généralisée, le contrôle des propriétés mécaniques des pièces…

Modélisation et Évaluation Analytique du Temps de Réponse des Systèmes de Contrôle-Commande Distribués en utilisant des Réseaux de Petri et l'Algèbre des Dioïdes

The problem addressed in this thesis concerns above all the analytical evaluation of a response time bound for a distributed control system, in a critical industrial context. The teleology of the work is therefore to prove this bound by a method…

Combining Model-based and Data-based approaches for online predictions of human trajectories

Accurately predicting human movement trajectories is of critical interest in multiple fields, including humanexoskeleton interaction. In general, such predictions can be obtained from model-based approaches (e.g., optimal control theory) or from…

A methodology for weld bead geometry and operating conditions determination in Wire Arc Additive Manufacturing

When manufacturing a part using Directed Energy Deposition (DED) pro-cesses such as Wire Arc Additive Manufacturing (WAAM), it is necessary to determine the deposition path and operating parameters (wire feed speed, torch speed, energy). While the…
