The present study focuses on the analysis of AISI-52100 steel hard-turning with standardised square inserts. The process is being studied in terms of the resultant cutting force and the cutting power under a wide range of four key machining parameters: the cutting speed, the feed rate, the depth of cut and the tool nose radius. First of all, an updated finite element method (FEM) model has been used to generate a dataset, which in turn was used to train an artificial neural network (ANN), minimising this way the required experimental work and the utilisation of high amounts of computing resources. The developed networks were evaluated with regard to their reliability, revealing increased levels of accuracy. The mean absolute percentage error (MAPE) was calculated equal to 8.1% for the force prediction network and 11.2% for the power prediction network, respectively. Furthermore, the multivariate interaction was evaluated and visualised. Copyright © 2024 Inderscience Enterprises Ltd.

In the design of bodily engaging Mixed Reality (MR) installations for intangible cultural heritage (ICH) in museums, a gap remains regarding how to test low-fidelity prototypes to refine the detailed design and ensure successful final implementation. By integrating bodystorming early in the design thinking process, alongside lab-based experience prototyping, this study proposes a method to foster a deeper empathetic connection between cultural practitioners and the public, thereby enhancing visitor experiences. Focusing on the ICH of wooden shipbuilding, the process involves stakeholders and users from conceptualization to prototype testing, ensuring that final interactive installations are user-centered and culturally resonant. The findings demonstrate how this participatory design approach bridges digital technologies with traditional cultural practices, providing methodological insights for the transmission of ICH and visitor engagement that other designers can adopt. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

ASME Letters in Dynamic Systems and Control 2024年第4期4卷 041006页

作者： Stravopodis, N. Moulianitis, V.C. Department of Product and Systems Design Engineering University of the Aegean Ermoupolis Syros84100 Greece Department of Mechanical Engineering University of the Peloponnese Patra Achaia263 34 Greece

In this work, a framework is proposed for the analytical formulation of dynamic equations for serial metamorphic manipulators using screw theory tools. The integration of structure reconfiguration is achieved in a compact and comprehensive manner. Based on the previously proposed modular structure representation, additional statements are provided to strictly define the metamorphic structure assembly. To validate the precision of the extracted dynamics, two simulations are performed for paths defined in Cartesian space. The generated trajectory is evaluated by comparing the dynamic matrices produced by the proposed method with those from an established dynamic modeling algorithm. Additionally, the trajectory is simulated in an open-source simulator, and the torques extracted from system dynamics are compared with the corresponding simulator torques under the same kinematic constraints. © 2024 by ASME.

Multivariate modelling of AA6082-T6 drilling performance using RSM, ANN and response optimization

引用

International Journal of Lightweight Materials and Manufacture 2024年第4期7卷 531-545页

作者： Tzotzis, Anastasios Antoniadis, Aristomenis Kyratsis, Panagiotis Department of Product and Systems Design Engineering University of Western Macedonia Kila Kozani50100 Greece Department of Production Engineering and Management Technical University of Crete Kounoupidiana Chania73100 Greece

The AA6082-T6 was experimentally studied in the present research with respect to the drilling performance. Drill diameter, cutting speed and feed rate were examined, using a full factorial design. Mathematical modelling of the process was carried out using the Response Surface Methodology (RSM) as well as the Artificial Neural Network (ANN) techniques. The output results in terms of cutting force, torque and surface roughness, revealed high levels of correlation between the experimental and the predicted data. Specifically, the Mean Absolute Percentage Error (MAPE) values using RSM compared to the ones of the experiments, were equal to 2.14%, 3.49% and 6.16% for Fz, Mz and Ra respectively. The equivalent MAPE between the ANN and the experiments were found to be 2.19%, 1.82% and 2.85% accordingly. Moreover, the most significant terms were revealed, being the interaction D × f for the thrust force and the torque with contribution percentages equal to approximately 44% and 42% respectively, and the term D2 for the surface roughness with 51%. The evaluation of the machining parameters, identified their significance, enabling the selection of the optimal cutting parameters, which were obtained by the desirability function, taking into account the importance of the generated surface quality and the reduction of cost. The solutions given by this approach, pointed out the Ø9 tool, coupled with Vc = 50 m/min and f = 0.15mm/rev as a well-balanced combination, whereas the Ø9.9 tool used under the same conditions, yielded the best possible surface quality (appr. 0.2 μm). © 2024 The Authors

This paper explores specifically designed workshops, referred to as Knowledge Sharing Sessions (sessions), emphasizing their transdisciplinary nature. These sessions serve as convergence points for academia and industry to collaborate and integrate knowledge, addressing complex concepts such as boundary crossing and boundary objects. The sessions comprised two types: six theory-driven sessions led by researchers, discussing theoretical concepts related to boundary crossing and boundary objects, and four practice-driven sessions led by practitioners, focusing on the means and objects employed by their respective companies to cross boundaries between disciplines in product realisation. These sessions involved three researchers and practitioners from five large and medium-sized manufacturing companies in the Swedish industry. During the sessions, practitioners found themselves challenged by researchers to grasp and reflect upon complex concepts, while researchers faced the task of operationalizing intricate concepts like boundary objects, making them accessible and understandable for practitioners. Expanding such insights can empower practitioners to strategically design objects that effectively serve as boundary objects, thus facilitating the crossing of boundaries between disciplines. Based on the experiences gained from these sessions, the design appears relevant to strengthen transdisciplinary engineering efforts. © 2024 The Authors.

To achieve relevant research results, collaborative research is deemed essential in several engineering and management disciplines. When the addressed research questions are associated with larger societal challenges the need for collaboration between various actors and disciplines becomes even more urgent. In this paper, the development of a transdisciplinary research initiative aiming at supporting long-term ability for the manufacturing industry to succeed with the green transition, is described. The transdisciplinary research programme ´GRACE - Green acceleration through integrated and platform-enabled product realisatioń is an eight-year project (4+4 years), involving eleven manufacturing industries and four industrial networks. The research programme GRACE is the result of a close collaboration between industrial partners and academic researcher for almost one year. We have through workshops and various meetings jointly formulated a research agenda, based on eight research issues: (1) requirement specification and management, (2) platform principles and lifecycle strategies on different system levels, (3,4) product design and production solutions supporting circular strategies, (5,6) product and production information management, (7) shared understanding and visions, and (8) knowledge integration, operationalisation and implementation. Based on these research issues, and the priorities among the industrial partners, three initial research projects have been developed. The development of the research programme applied a co-production process, including a distinct pre-project phase. The creation of the transdisciplinary programme GRACE required trust among the involved partners, an open atmosphere, structure, joint understanding among the participants, time to read and think, and some stubbornness. © 2024 The Authors.

A challenge in product realisation, involving several functions and individuals with various specialisation, is knowledge integration. The purpose of this paper is to advance the understanding of how and when boundary objects can enable knowledge integration in a product realisation contex. Examples of possible boundary objects in the context of product realisation are engineering drawings and prototypes. Boundary objects are situational, meaning that an object may function as boundary object in one situation, but not in another. It is therefore essential to understand under what circumstances you can expect an object to function as a boundary object. Based on literature and the results from empirical studies, a four-step process assessing the potential of an object to function as a boundary object in a specific situation was developed. The suggested ´boundary object assessment procesś can be a way for manufacturing companies to achieve awareness of how, for example, engineering drawings or prototypes can be used to their full potential as boundary objects. Furthermore the ´boundary object assessment procesś contributes to theory on knowledge integration in product realisation, through the compilation of existing but fragmented evidence on boundary object applications. In addition, boundary objects have the potential to integrate knowledge between disciplines, i.e., supporting transdisciplinary work, and through the suggested ´boundary object assessment procesś the possibility to succeed with this may increase. © 2024 The Authors.
