Planning the machining of dies and moulds

The basic planning stages of the machining process and the use of CAD/CAM system to reduce the machining time and improve geometrical quality of the machined die are analyzed. The geometry of the dies or mould and the minimum radii demands and maximum cavity depth should be carefully studied. Maximum productivity can be reached by adapting the size of the milling cutters and the inserts to a certain die or mould and to each specific operation. The CAD/CAM-systems can be used in much better ways using new ways of thinking and approaching an application. It is suggested that round insert cutters with small run-outs can in combination with ground, positive and light cutting geometries be used in semifinishing and some finishing operation.
