Description succincte (Anglais)	Micro EDM milling II - Modular system for high-precision micro-EDM-milling manufacturing technology
Résumé des résultats (Abstract) (Anglais)	The 'discovery' project CTI 8501.2 has explored the physical basis of the micro-EDM-milling and proved its feasibility: - Micro-EDM-milling feasibility achieved for electrode between 0.2 to 0.8 mm. - Machining demonstration of cavities with high aspect ratio (h/l ~ 30) in hard steel or tungsten carbide. There is a great interest to convert micro-EDM-milling into an industrial product as this technology make possible manufacturing parts that are today unfeasible with milling or die sinking technology. The goal of this 2nd project proposal is to be able to convert micro-EDM-milling into an industrial product. the basic ideas of this future project are - Design of simplified and robust electrode holder (allowing easy electrode¿s change), for diameter down to 0.1 mm. - Automatic system for straight electrode recovery. - Development of an intelligent spark generator with self regulation of material removal allowing constant speed tool path. This is much innovative as it brings a great simplification of the process control; this will allows the integration of future micro-EDM-milling module on different platforms. - Setup of a new method to control the electrode¿s vibration and wear based on spark signal analysis, improving the precision and facilitating the integration of micro-EDM-milling on a modern CNC controller as well as on high-speed milling CAD-CAM systems. The signal analysis will also be able to deliver a 3D image of the machined surface thus giving the possibility of a corrective action during sequential layer machining. - Full 3D characterization of the high aspect ratio parts issued from this technology. Such modular system will be quickly implemented on different existing platforms thus reducing time to market and giving the best fit to advanced customer needs in mould, die and production manufacturing.
