The Tooling Instructor Software – A New Approach For Decision Support In Tool Design

The paper describes the development of software which supports tool designers in the derivation of an appropriate mould design from the casting geometry. This system is to be used in conjunction with a CAD/CAM software. BIBA is developing this software within the European Community funded GROWTH project GRD1-2000-10866 DIRECTOOL. The main focus of the work concerns casting applications. In co-operation with project partners from the castings industry tooling design knowledge has been acquired which forms the basis for the software. A large variety of tool designs from injection moulding to gravity die casting has been analysed with regard to the relevant tooling characteristics. The results have been used to develop a reference model which is capable of mapping tool designs relating their relevant features. The paper describes, how this reference model has been used for the implementation of decision support software for gravity die designs. The two-step-decision-support consisting of Case Based Reasoning (CBR) and interactive design support is presented using a case study. First experiences have been made with the software prototype at Walter Frank & Sons Ltd., a UK foundry which specialises in gravity die casting aluminium.
