To the single processes or work steps a lot of specific databases ara available, whose data contains redundancies and inconsistencies. Examples are databases about casting defects, design rules or physic variables and so on. A multitude of direct and indirect cause variables must be considered. For instance the moulding and casting process, the casting shape, the complexity of the casting, the dimensions, requirements to the surface quality of casting outlines, the material and the gating and risering system. The worker, which execute the generation of raw parts, uses the mentioned connections in an iterative and interactive process.
Many foundries are depend on the expert knowledge of the workers.
But this is a critical handicap in the competition and so it is tried to rationalize the field of raw part generation, in order to use new technology resp. The aim of the information fusion is to find dependencies over all databases and to support the casting design process with help of these information. Through the interaction of several databases the expert knowlegde of the engineer is supported and completed. For instance the connection of information about casting technology and information about avoidance of casting defects is very important. Another example in our project is the use of data about already arised casting defects in order to select all kinds of moulding and casting processes from a database.
