The competitiveness of the machining process in terms of productivity and quality is maintained due to the permanent evolution of the CNC machines kinematics and the CAD-CAM software functionality. The main objective of the CFAO team is the production of mechanical workpieces having functional surfaces with complex shape machined on high-speed multi-axis machines. The team conducts research and development in the field of material removal machining by focusing on the indispensable triple components in machining: workpiece, cutting tool and machine tool. In parallel, the team is interested in the design and realization of mechanical systems dedicated to different socio-economic sectors.

 

 

Projects:

  • Socio-economic:
