Publication Access status: Open Access , Datengestützte Umformtechnik: Künstliche Intelligenz zwischen Prozesswissen, Regelung und ProduktionsrealitätWith the 7th Biegeforum, the Chair of Forming Technology at the University of Siegen once again offers researchers the opportunity to present their topics and findings to a specialist audience from industry and academia. This conference volume brings together current research findings and innovative developments in forming technology, highlighting the broad scope of the research field. The Biegeforum thus underscores its role as a key platform for exchange between research and industry — a role it has fulfilled since its first edition in 2011.Source Type:Conference ProceedingsSeries:Forschungsberichte des Lehrstuhls für Umformtechnik1 30 - Some of the metrics are blocked by yourconsent settings
Publication Access status: Open Access , Enabling scalable and flexible production through digital twin-based robot–machine commissioningThis paper presents a conceptual method for a digital twin–based framework for scalable, flexible robot–machine commissioning in batch production processes. Following the concept of virtual commissioning as defined in VDI 4499, this method proposes a robot-first, event-driven interaction paradigm in which a mobile manipulator initiates transportation, handling, and manipulation tasks while production machines remain in a ready state and respond to the robot's actions. The approach is validated through a proof-of-principle demonstration using a nine-degree-of-freedom mobile manipulator (SkaBot9) with an integrated shelf. The complete process logic and communication architecture are simulated and transferred to the physical system without structural changes. The results demonstrate that the proposed method supports early validation of robot–machine interaction and a potential for commissioning with flexible, mobile robot–based production systems.Source Type:InProceedings - Some of the metrics are blocked by yourconsent settings
Publication Access status: Open Access , Human Assistance System Supporting Forming Machine ReconfigurationIncreased product complexity in present manufacturing sector, shorter product lifecycles, and more variable customer demands, require production systems to be flexible and reliable. As a result, machines are required to be reconfigured more frequently and within shorter timeframes. Reconfiguring forming machines is a complex and delicate task that depends strongly on operator experience and practical know-how gained over several years. Appropriate support system is required to transfer the accumulated experience and knowledge in order to enable novice operators to perform such tasks effectively. This work presents an assistance system designed to support novice operators during forming machine reconfiguration tasks. The proposed system comprises an eye-gaze sensor to observe operator actions and visual attention during task execution. Based on this information, the system identifies potential mistakes and provides real-time feedback on a smartwatch to guide the operator through the reconfiguration process. The approach is evaluated in a controlled laboratory environment, where both task performance and user experience are assessed. The results show potential for the use of human assistance systems to support novice operators in real time during forming machine reconfiguration on the shop floor. In addition to improving the overall system and its evaluation in a real production environment under industrial conditions, future work will focus on multimodal sensor fusion to enable more robust intent recognition and contextual understanding of an operator during reconfiguration of forming machines.Source Type:InProceedings
