Smart Foundry - Informationstechnische Unterstützung der Planung, Konstruktion und Fertigung von Formen für den Metallguss

Die Europäische Gießereiindustrie besteht zu einem großen Teil aus Klein- und Mittelständischen Unternehmen, die in Summe einen bedeutenden Anteil der produzierenden Industrie Europas bilden. Traditionell sind diese Unternehmen lediglich in einem geringen Umfang an Forschungs- und Entwicklungsaktivitäten beteiligt, was vielerorts den Einsatz veralteter Technologie und der damit verbundenen Prozesse zur Folge hat.

KNOWLEDGE-BASED MANUFACTURING STRATEGY AND METHODS FOR FOUNDRIES

The European foundry business is a traditional less RTD intensive industry which is dominated by SMEs and which forms a significant part of Europe’s manufacturing industry. The efficient design and manufacturing of cast components and corresponding tooling is a crucial success factor for these companies. To achieve this, information and knowledge around the design, planning and manufacturing of cast components needs to be accessible in a fast and structured way.

A General Solution Framework for Component-Commonality Problems

Component commonality - the use of the same version of a component across multiple products - is being increasingly considered as a promising way to offer high external variety while retaining low internal variety in operations. However, increasing commonality has both positive and negative cost effects, so that optimization approaches are required to identify an optimal commonality level. As components influence to a greater or lesser extent nearly every process step along the supply chain, it is not surprising that a multitude of diverging commonality problems is being investigated in literature, each of which are developing a specific algorithm designed for the respective commonality problem being considered. The paper on hand aims at a general framework which is flexible and efficient enough to be applied to a wide range of commonality problems. Such a procedure based on a two-stage graph approach is presented and tested. Finally, flexibility of the procedure is shown by customizing the framework to account for different types of commonality problems.
