Design framework for managing the life cycle of Kinematic Digital Twins

Mass customisation calls for new innovative solutions such as the Digital Twin (DT) concept. DT enhances the classical sequential design-manufacture-usage life cycle into a more flexible concept that can handle the changes stemming from the physical realization of the nominal design. One of the greatest challenges of real-izing a Kinematic Digital Twin (KinDT), where movement modelling is of upmost importance, is the synchro-nisation of the as-built model with the as-designed model. Consequently, this paper proposes a design framework to support the synchronisation and feedback information within the DT. The usage of the frame-work is demonstrated in two robotic applications.& COPY; 2023 The Authors. Published by Elsevier Ltd on behalf of CIRP.
