Based on CAD/CAM information, the technology of NC-milling offers considerable advantages for the machining of complex-shaped dies. As a prerequisite, however, the geometry-oriented NC-functions have to be enhanced by appropriate technology modules. For roughing operations, favourite engagement conditions as well as an optimized preparation of the finishing process are to be mentioned. If the cutting parameters are carefully selected, superhard cutting materials, such as cemented carbide or CBN, can be used for finish milling. The effect of these actions is a considerable increase in machining quality as well as a drastic reduction of machining time. Furthermore, the manual correction of dies can be avoided in many cases.
