Chapter . An integrated knowledge-based system for sheet metal processing

Y. Rao[a], J. Efstathiou[b]


This paper presents an integrated knowledge-based CAD/CAM system for sheet metal cutting-punching combination processing. The whole system consists of five functional modules, i.e. modeling, nesting, process-planning, NC-programming and simulation & reporting module, which are integrated seamlessly in terms of data processing. The knowledge base is the core of the integrated system, based on which, the system runs in an efficient and intelligent manner. This system has been successfully applied in industry, and an application example is demonstrated.


Cutting and punching are two frequently applied processes in the sheet metal ...
