Lines of research
Our laboratory, aiming at a recognition in the Université Paris-Saclay as a major actor in the field of the factory of the future, concentrates its strengths towards four main research focuses, in the continuity of it's historical themes. But the guidance is now set on the notions of smart product and smart manufacturing within industry 4.0, with the notion of digital twin in sight.
Digital twin
In the background, the laboratory is establishing a federative digital twin pilot project, configurable and predictive, either at the smart product or at the smart manufacturing level. This project is fed on the one hand by multi-scale models, multi-physical integrating geometric and non-geometric faults, and on the other hand by in-situ measurements of the parts or systems producing them.
Line 1: Shape acquisition, identification and processing
Line 2: Numerical models for the specification and control of geometric variations of products
This axis integrates on the one hand the geometrical tolerance through multi-physical models aimed at predicting, via simulation, the deviations of the geometry of the parts and their influence on the assemblies.
Line 3: Manufacturing processes, performance and steering of poly-articulated systems
The laboratory develops tools, models and protocols allowing the qualification, the optimization of performances and the piloting of poly-articulated systems intended for 3D measurement and manufacturing. Multi-sensor / multi-scale in-situ measurement processes will be developed for monitoring and automated modification of manufacturing processes.
This work will mainly build on existing experimental platforms, namely the SLM additive manufacturing cell, the high-speed 5-axis machining center and the robotic cell. This will be completed as part of the FAPS project to implement additive manufacturing processes (deposition of metal wire by laser fusion) subtractive by machining and polishing, and in-situ measurement. Our efforts will have to be maintained in order to have sufficient qualified personnel to operate these instruments.
