Abstract

The digital twin (DT) has become a key component for the digitalisation, monitoring, and improvement of manufacturing systems. This has led to the development of various DTs for distinct workpieces, processes, and tools. While beneficial, these individual components need to be configured to form a system of DTs that represents the overall manufacturing system, a task that is nontrivial but necessary to realise a truly smart manufacturing system. This paper proposes an identification scheme to distinguish each unique DT within a system of DTs (Digital Twin System) from three aspects: the physical entity, the digital representation and connections. Based on it, non-identical DTs are proposed as different digital representations of the same element or elements in a manufacturing system. They are sorted into three classes, including homologous DTs, heterologous DTs, and exclusive DTs, based on their context and behaviour. Definitions and characterisations of three types of non-identical DTs are then discussed. Lastly, a case study of in-situ failure detection for material extrusion(MEX) additive manufacturing is demonstrated to explore affordances, challenges, and potential applications of non-identical DTs.
