Objectif
The ever growing competition on the international markets pushes manufacturers towards shorter design cycles and decreasing manufacturing times and costs for their products. This trend generates a demand for smart, flexible and faster machining systems, easy to set up and configure, which are able to drastically reduce machining time, while improving the final accuracy. Machine axis acceleration of speed 3-5 times higher than conventional ones together with machining accuracy in the range of 0.5-1 µm will be the most probable targets of the new generation of machining systems inside manufacturing shops. Inertial forces, dynamic vibration and stability problems arising from such an accelerations will be so big that, if no suitable solutions are provided, the precision and machining quality will be definitely endangered. Strong mass reduction of mobile machine parts together with the increasing of their stiffness and damping to get excellent static, dynamic and thermal stability of the structures is becoming a 'must', to ensure a technological and cost-effective achievement of such an ambitious goals. Conventional materials for building machine tools are commonly cast iron, welded steel and income case aluminium-alloy. Recently, especially in some running EU projects studies have been carried out to introduce polymeric matrix composites (PMC-fibbers reinforced) materials, aluminium Honeycomb and glued structures. Even if good results in term of mass reduction and damping increasing seem to be achieved within such a projects, this will be absolutely not enough to get the declared excellent technological machine performances. The research will be focused on new materials for macro scale applications to reach a full and deep integration between structural and macaroni parts of the machines in order to get an "Unicom" solution able to perform itself all the required functions. Therefore the primary goals is to achieve cost-effective'
