The key factor to success, towards a competitive energy consumption reduction, is the effective involvement of SMEs both in the use of more efficient machines and in the Design of an Environment for new products. A specific product can be manufactured in different ways, based on cost optimization rather than on production flexibility and energy efficiency with the involvement of different suppliers. The ENEPLAN project aims at the development of a digital and real, energy-efficient, multi-process, networked, manufacturing system, adapted to the functional specifications of metal formed or machined parts for automotive, aeronautic and domestic appliances. Seventeen partners, coming from seven European countries and the participation of OEMs, SMEs, RTD and technology providers, who work jointly to deliver through ENEPLAN a manufacturing planning decision support tool (meta-CAM tool), for the optimization of the plant operation. This tool will be used from the conceptual phase of the product (final blueprints) to its final dispatch to the customer. This paper will provide a short overview of the ENEPLAN project and its ongoing developments, while the existing results will be presented and discussed and the next steps will be described.
