This paper describes CHAMP, a conceptual architecture designed to support the task of passing information from computer-aided design systems to computer-aided process planning systems.1 Current integration systems are lacking in the flexibility of both their information-exchange mechanisms and in their control structures. The result is a sacrifice in the efficiency of solutions produced. The proposed architecture is based on models of human process planning, and aims to improve the effectiveness of CAD/CAPP integration by providing more flexible communications and control structures through shared blackboards, and by providing a mechanism for reasoning about intermediate solution states. The architecture is intended to summarize the current understanding of the CAD/CAPP integration task and to elucidate areas where further research is required.
