Abstract
The paper proposes implementation of predictive control strategies on an industrial machining centre dedicated to high speed machining, realized within the framework of a CETIM study. Modelling, parameters identification and performances of the robustified axes drive polynomial controllers are first validated within a virtual machine–tool environment. Implementation is then achieved on the AXELOR 20SL machining centre, equipped with a Power Automation CNC. The computation of the controllers is carried out through the concept of compile cycles for real time scheduling. Results obtained with predictive control when machining a complex workpiece are finally compared to those achieved with the classical CNC control architecture.
