Regarding the economical and ecological challenges of machining difficult-to-cut alloys, this project aims to study a new eco-friendly cooling and lubrication method, using supercritical dioxide carbon (ScCO2). Based on the cooling ability (phase change) and the "green solvent" properties of ScCO2, this project investigates the impacts of ScCO2 on the cutting zone, to understand the thermal and tribological phenomena, for reliable modelisation and improved applications. A special multitasks setup, named "VENUS", has been designed and built by LaBoMaP, to conduct machining experiments with ScCO2 and explore the abilities of the technology. Many laboratories have joined LaBoMaP to extend as far as possible, the scope of the project, namely, LIFSE (fluids dynamics), LAMPA (machining and tribology), Institut CHAMBERY (life cycle assessment) and CETIM (Technical centre for the mechanical industry).
