Development of efficient milling technology using integrated process simulation

The aims in machining of dies and moulds are high machining speeds in <http://dict.leo.org/ende?lp=ende&p=thMx..&search=in> conjunction with <http://dict.leo.org/ende?lp=ende&p=thMx..&search=with> high production accuracy and surface quality. Therefore new strategies in computer-aided manufacturing and advanced control concepts are required. The machine control has to consider the dynamic behaviour of the machine tool, of the drives and the milling tools to adjust the milling path and the feed actually during machining. The deformation behaviour of the machine tool and the cutting tool are determined. For that purpose finite element simulations were done. The results of the simulations were stored in databases to which the machine control has access. This control strategy was proved in milling tests. The tests validate the achievement potential of the realised compensation algorithms. Using the same feed rates milling with the new control strategy produce a better surface quality and a smaller geometrical error. Hence, a higher feed rate and higher acceleration may be chosen.
