[{"doi":"10.21741/9781644902479-220","abstract":[{"lang":"eng","text":"Abstract. Climate change, rare resources and industrial transformation processes lead to a rising demand of multi-complex lightweight forming parts, especially in aerospace and automotive sectors. In these industries, flow forming is often used to produce cylindrical forming parts by reducing the wall thickness of tubular semifinished parts, e.g. for the production of hydraulic cylinders or gear shafts. The complexity and functionality of flow forming workpieces could be significantly increased by locally graded microstructure and geometry structures. This enables customized complex hardness distributions at wear surfaces or magnetic QR codes for a unique, tamper-proof product identification. The production of those complex, 2D (axial and angular) graded forming parts currently depicts a great challenge for the process and requires new solutions and strategies. Hence, this paper proposes a novel control strategy that includes online measurements from an absolute encoder to determine the angular workpiece position. Workpieces of AISI 304L stainless steel with 2D-graded structures are successfully manufactured using this new strategy and analyzed regarding the possible accuracy and resolution of the gradation. At this point, a dependency of the gradations on the sensor and actuator dynamics, accuracy and geometry could be noted. It is further evaluated how the control strategy could be extended by an observer-based closed-loop property control approach to enhance the accuracy of the suggested strategy.

In the field of manufacturing technology, a wide variety of approaches are being used to improve both resource and energy efficiency. Efficiency as well as sustainability can be improved by creating a circular economy or through energy-efficient recycling processes. As part of the interdisciplinary research group \"Light—Efficient—Mobile\" investigations on the energy-efficient friction-induced recycling process have been carried out at the department of Forming and Machining Technology at Paderborn University. E.g. using the friction-induced recycling process, different formless solid aluminum materials can be direct recycled into semi-finished products in an energy-efficient manner. The results of investigations with regard to the influence of the geometrical shape and filling rate of the aluminum particles to be recycled as well as the rotational speed of the continuously rotating wheel are explained in this paper. In addition to the recycling of aluminum chips, aluminum particles like powders from the field of additive manufacturing are processed. Based on these results, the future potentials of solid-state recycling processes and their contribution to the circular economy are discussed. The main focus here is on future interdisciplinary research projects to achieve circularity in the manufacturing of user-individual semi-finished products as well as the possibility to selectively adjust the product properties with the continuous recycling process.","lang":"eng"}],"volume":16,"issue":"6","article_number":"59","quality_controlled":"1","publication":"International Journal of Material Forming","type":"journal_article","publication_status":"published","citation":{"mla":"Borgert, Thomas, et al. “Potentials of a Friction-Induced Recycling Process to Improve Resource and Energy Efficiency in Manufacturing Technology.” International Journal of Material Forming, vol. 16, no. 6, 59, Springer Science and Business Media LLC, 2023, doi:10.1007/s12289-023-01785-w.","bibtex":"@article{Borgert_Milaege_Schweizer_Homberg_Schaper_Tröster_2023, title={Potentials of a friction-induced recycling process to improve resource and energy efficiency in manufacturing technology}, volume={16}, DOI={10.1007/s12289-023-01785-w}, number={659}, journal={International Journal of Material Forming}, publisher={Springer Science and Business Media LLC}, author={Borgert, Thomas and Milaege, Dennis and Schweizer, Swetlana and Homberg, Werner and Schaper, Mirko and Tröster, Thomas}, year={2023} }","short":"T.

In this work, various secondary structures applied on the PPHE surface were studied numerically to explore their potential to enhance near-wall mixing. Computational fluid dynamics (CFD) simulations of single-phase turbulent flow in the outer PPHE channel were performed and pressure drop, heat transfer coefficients, and overall thermo-hydraulic efficiency were determined.

They can be categorised into technologies which require an auxiliary joining element, or do not require an auxiliary joining element. A typical example for a mechanical joining process with auxiliary joining element is self-piercing riveting. A wide range of processes exist which are not requiring an auxiliary joining element. This allows both point-shaped (e.g., by clinching) and line-shaped (e.g., friction stir welding) joints to be produced. In order to achieve versatile processes, challenges exist in particular in the creation of intervention possibilities in the process and the understanding and handling of materials that are difficult to join, such as fiber reinforced plastics (FRP) or high-strength metals. In addition, predictive capability is required, which in particular requires accurate process simulation. Finally, the processes must be measured non-destructively in order to generate control variables in the process or to investigate the cause-effect relationship. This paper covers the state of the art in scientific research concerning mechanical joining and discusses future challenges on the way to versatile mechanical joining processes."}],"doi":"10.1016/j.jajp.2022.100113","title":"Review on mechanical joining by plastic deformation"},{"intvolume":" 926","author":[{"full_name":"Dahms, Frederik","first_name":"Frederik","id":"64977","last_name":"Dahms"},{"id":"233","last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner"}],"conference":{"end_date":"29 April 2022","name":"25th International Conference on Material Forming (ESAFORM 2022)","location":"Braga, Portugal","start_date":"27 April 2022"},"department":[{"_id":"156"}],"publication_status":"published","citation":{"apa":"Dahms, F., & Homberg, W.

Due to plastic deformation of metastable austenitic steel, phase transformation from γ-austenite into α’-martensite occurs. This is initiated by the formation of shear bands as product of the external stresses. By means of coupled microscopic and micromagnetic investigations, a characterization of the microstructure was carried out. In particular, this study shows the distribution of the strain-induced α’-martensite and its influence on material properties like hardness at different depths. The microstructural analyses by means of electron backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite (ca. 23 %) close to the outer specimen surface, where the plastic deformation and the direct contact with the forming tool take place. In the middle area (ca. 1.5 mm depth from the outer surface), the portion of transformed α’-martensite drops to 7 % and in the inner surface to 2 %. These results are well correlated with microhardness and micromagnetic measurements at different depths. EBSD and atomic force microscopy (AFM) were used to make a detailed characterization of the topography and degree of deformation of the shear bands. Likewise, the mechanisms of nucleation of α’-martensite were discussed. This research contributes to the development of micromagnetic sensors to monitor the evolution of properties during flow forming. This makes them more suitable for closed-loop property control, which offers possibilities for an application-oriented and more efficient production."}],"doi":"10.1515/pm-2022-0064","title":"Coupled microscopic and micromagnetic depth-specific analysis of plastic deformation and phase transformation of metastable austenitic steel AISI 304L by flow forming","issue":"11","page":"660-675","volume":59,"type":"journal_article","quality_controlled":"1","publication":"Practical Metallography"},{"intvolume":" 926","author":[{"last_name":"Kersting","first_name":"Lukas","full_name":"Kersting, Lukas"},{"first_name":"Bahman","full_name":"Arian, Bahman","last_name":"Arian","id":"36287"},{"last_name":"Vasquez","first_name":"Julian Rozo","full_name":"Vasquez, Julian Rozo"},{"full_name":"Trächtler, Ansgar","first_name":"Ansgar","last_name":"Trächtler","id":"552"},{"last_name":"Homberg","id":"233","first_name":"Werner","full_name":"Homberg, Werner"},{"last_name":"Walther","full_name":"Walther, Frank","first_name":"Frank"}],"department":[{"_id":"156"},{"_id":"153"},{"_id":"241"}],"citation":{"ama":"Kersting L, Arian B, Vasquez JR, Trächtler A, Homberg W, Walther F.

The production of parts with complex geometry and locally graded material properties currently depicts a great challenge in the flow forming process. At this point, the usage of closed-loop control for the shape and properties could be a feasible new solution. The overall aim in this project is to establish an intelligent closed-loop control system for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces in a flow forming process. To reach this goal, a novel sensor concept for online measurements of the wall thickness reduction and the martensite content during forming process is proposed. It includes the setup of a modified flow forming machine and the integration of the sensor system in the machine control. Additionally, a simulation model for the flow forming process is presented which describes the forming process with regard to the plastic workpiece deformation, the induced α’-martensite fraction, and the sensor behavior. This model was used for designing a closed-loop process control of the wall thickness reduction that was subsequently realized at the real plant including online measured feedback from the sensor system.","lang":"eng"}],"title":"Innovative Online Measurement and Modelling Approach for Property-Controlled Flow Forming Processes","user_id":"36287","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"type":"journal_article","quality_controlled":"1","publication":"Key Engineering Materials","page":"862-874","volume":926},{"department":[{"_id":"156"},{"_id":"241"}],"citation":{"ama":"Rozo Vasquez J, Walther F, Arian B, Homberg W, Kersting L, Trächtler A.

By controlling workpiece properties during the process, beneficial effects caused by forming can be exploited and integrated in the product design. The overall goal of this investigation is to produce tailored tubular parts with a defined locally graded microstructure by means of reverse flow forming. For this purpose, the proposed system aims to control both the desired geometry of the workpiece and additionally the formation of strain-induced α′-martensite content in the metastable austenitic stainless steel AISI 304 L. The paper introduces an overall control scheme, a geometry model for describing the process and changes in the dimensions of the workpiece, as well as a material model for the process-induced formation of martensite, providing equations based on empirical data. Moreover, measurement systems providing a closed feedback loop are presented, including a novel softsensor for in-situ measurements of the martensite content.","lang":"eng"}],"doi":"10.1016/j.aime.2021.100057"},{"_id":"21477","date_updated":"2023-04-27T08:42:00Z","publisher":"Springer, Cham","date_created":"2021-03-12T11:11:35Z","status":"public","year":"2021","publication_identifier":{"isbn":["978-3-030-75380-1"]},"language":[{"iso":"eng"}],"publication_status":"published","series_title":"Forming the Future.

To achieve this, it is necessary to employ an appropriate process or tool design. While this will generally prove successful, it cannot, however, offset stochastic defects with local variations in material properties. Closed-loop process control represents a promising approach for a solution in this context. The state of the art involves using this approach to control geometric parameters such as a length. So far, no research or applications have been conducted with closed-loop control for microstructure and product properties. In the project on which this paper is based, the local martensite content of parts is to be adjusted in a highly precise and reproducible manner. The forming process employed is a special, property-controlled flow-forming process. A model-based controller is thus to generate corresponding correction values for the tool-path geometry and tool-path velocity on the basis of online martensite content measurements. For the controller model, it is planned to use a special process or microstructure (correlation) model. The planned paper not only describes the experimental setup but also presents results of initial experimental investigations for subsequent use in the closed-loop control of α’-martensite content during flow-forming."}],"_id":"23465","date_updated":"2023-05-02T08:27:48Z","quality_controlled":"1","date_created":"2021-08-23T13:00:35Z","publisher":"ULiège Library","publication_identifier":{"eisbn":["978-2-87019-303-7"],"isbn":["978-2-87019-302-0"]},"year":"2021","type":"conference","language":[{"iso":"eng"}],"status":"public"},{"department":[{"_id":"156"}],"publication_status":"published","user_id":"7888","citation":{"chicago":"Wiens, Eugen, Werner Homberg, Bahman Arian, Kerstin Möhring, and Frank Walther. “Forming of Parts with Locally Defined Mechanical and Ferromagnetic Properties by Flow-Forming.” In Forming the Future.
