KAD/KAM: the next generation of CAD/CAM

The first CAD/CAM generation [1970-1990] was graphic and geometric. The second generation [1980-2000] is coupling the first one to DBMS, it is still under development. The third generation called KAD/KAM (Knowledge Aided Design/Knowledge Aided Manufacturing) is coupling the 2nd. generation to knowledge bases and will be developed during 1990-2010. This paper illustrates through the example of the CAD-X1 shell how knowledge bases can be integrated into CAD/CAM systems and how software architecture of KAD/KAM applications can be implemented.<
