This paper presents an approach for the development of easy-to-use tools with no learning curve, with lower licensing costs and can provide useful information to manufacturing engineers or technicians, helping them improve their yield and reliability with fewer trials. Examples of such tools are presented for liquid composite moulding processes, but can be extended to other processes. Note de contenu : - Approach - Image-based fibre perform permeability prediction tool - Web-based tools and software "calculators" - Automated tools - Workforce training - Consulting - Fig. 1 : Liquid Injection Moulding Simulation (LIMS software) can predict vent locations for successful mould filling in a complex mould, which may trigger race tracking along edges and corners resulting in 1024 possible flow patterns - Fig. 2 : Image-basee fabric permeability prediction tools (Ge-Mage-Flow3D software). After one has the values of the permeability of fabrics, that can be used as input for mould filling simulations - Fig. 3: Sequential VARTM infusion - Fig. 4 : Automated process analysis system. Depending on the levet of uncertainty, the user provides the available part data and receives encapsulated output. Software controllers convert the data, execute the simulation and extract the crucial information from the results. The operations of the software controller (s) and simulation software are transparent to the user. Note that: 11 the full simulation data can still be stored and reviewed, and (**) as the current implementation [4, 9, 10] is to serve the part designer, a simple cost analysis is possible - Fig. 5 : Conceptual schematic from CAD to automated manufacturing using sensors and simulations En ligne : https://drive.google.com/file/d/1J0ypf2DDAYtlADcduRJTGKjb558ZO1Ko/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30478 [article]
