Génération de Trajectoires "On-line" pour Machine à Commande Numérique Ouverte dans un Environnement de Programmation Avancée STEP-NC

Abstract : These research works aim to extend the possibilities for CNC machine tool programming allowing generation of on-line trajectories. The developed approach begins with an analysis of current programming evolution and limitations of legacy CNC. This analysis argues a lack and need for control optimization by taking into account some geometric data during the machining of a part. The choice is then focused on the use of open architecture CNC (OCNC), for which the criteria and integration on an industrial-size machine are elaborate. The developments made on the opportunities and entry points of the OCNC allow the validation and the implementation of corrective actions in real time, using an experimental study for measuring and disturbance of position of a workpiece being machined. On this basis, we structure the concept of an extended CNC (XCNC) by the use of the STEP-NC standard, which especially broadens the scope of corrective actions. Therefore, a study is made on the evolution of the manufacturing plant and CNC environment mutations, focusing on the impact of the XCNC throughout the manufacturing numerical chain.
