Abstract

A decision support system for the design of casting procedures D.F. Cowell, B. Knight & K. Freddy The University of Greenwich, Woolwich Campus, Wellington Street, Woolwich, London SE18 6PF, ABSTRACT This paper describes a current project to provide knowledge based support for the 'methoding' and design of casting procedures prior to the casting of metal products. The successful casting of a predesigned shape is vitally dependent upon the skill and experience of the foundry engineer, who performs a task known as 'methoding' the design, in order to determine a number of key elements prior to manufacture. The methoding process involves such decisions as the orientation of the shape, the positions and sizing of feeder reservoirs, allowing for metal contraction during freezing, the positioning of 'chills' to force freezing in some areas, and the sizing and positioning of the 'running system* in order to ensure suitable mould-filling. The project objectives are to produce
