Reducing the weight of vehicles can significantly lower the energy or fuel consumed and thus the emissions during operation. One possibility to assess this is the use of a property adapted multi-material systems containing high strength steel, light metals like aluminium or magnesium and fibre reinforced plastics. While expanding the number of materials used new challenges arise for the production and furthermore the joining technology to manufacture the vehicle made of the multi-material systems. One approach to overcome these challenges is to use innovative and adaptable joining techniques which allows the manufacturing of joints of different material combinations. Extensive research activities on the two stage thermo-mechanical joining process with adaptable joining elements was able to demonstrate the great potentials in terms of joining dissimilar materials with good strength. The previously kinematic and path-based fabrication of auxiliary joining elements is modified in this publication to a form-based approach with a perspective of establishing an efficient process chain using easily and cheaply available rods. Based on the new approach to produce the auxiliary joining elements, it can be demonstrated that a reproducible production of the geometry is possible for the investigated steel as well as aluminium material. </jats:p>"}],"citation":{"ieee":"T.

The raw material for this process is flat wire made of high-strength steel. During the manufacturing process of the flat wire, residual stresses and plastic deformations are induced into the wire. These residual stresses and deformations fluctuate over the length of the semi-finished product and have a negative effect on the final product quality. Straightening machines are used to reduce this influence to a minimum. So far, the adjustment of a straightening machine has been performed manually, which is a lengthy and complex task even for an experienced worker. This inevitably leads to the use of inefficient straightening strategies and causes high rejection rates in the entire production process. Due to a lack of sensor information from the straightening operation, application of modern feedback control methods has not been practicable. This paper presents a novel design for a straightening machine with an integrated, precise straightening force measurement. By simultaneously monitoring the position of the straightening rollers, state variables of the straightening operation can be derived. Additionally, a tension control for feeding the flat wire is introduced. This is implemented to mitigate the disturbing effects caused by irregularities in the wire-feeding process. In the results of this article, the high precision of the developed force measurement design and its possible applications are shown.","lang":"eng"}],"_id":"48781","volume":23,"user_id":"41470","status":"public","oa":"1","citation":{"ama":"Bathelt L, Scurk M, Djakow E, Henke C, Trächtler A.

Aufgrund der hohen erforderlichen Energiemenge in der primären Herstellung von Aluminium existieren hier im Vergleich zu anderen Konstruktionswerkstoffen große Einsparpotentiale. Mit dem in dieser Arbeit erforschten reibungsinduzierten Recyclingverfahren (RIR) wird eine alternative und energieeffiziente Prozessroute zum direkten Recycling von unterschiedlichen Aluminiumschrotten geschaffen. Zur Charakterisierung der Prozessroute werden u. a. die Erkenntnisse aus sich gegenseitig unterstützenden experimentellen und theoretischen Untersuchungen zu den Vorgängen der der Verdichtung, Plastifizierung als auch Extrusion der recycelten Profile dargelegt. Die Einflüsse unterschiedlicher Eingangsgrößen wie z. B. der Werkzeuggestaltung oder der Verarbeitung unterschiedlicher Legierungen werden zudem zur zukünftigen Auslegung des Prozesses erläutert. Aus der abschließenden energetischen Bilanzierung kann geschlossen werden, dass aufgrund der geringeren Verarbeitungstemperatur signifikante Energieersparnisse bei Verwendung des RIR im Vergleich zu den konventionellen Produktionsstrategien erzielt werden können.","lang":"eng"}],"date_created":"2023-10-16T07:13:03Z","type":"dissertation","department":[{"_id":"156"}],"title":"Reibungsinduzierter Prozess zum nutzerindividuellen und energieeffizienten Recycling von Aluminiumschrotten","year":"2023","status":"public","publication_identifier":{"isbn":["978-3-8440-9240-0"]},"author":[{"full_name":"Borgert, Thomas","last_name":"Borgert","first_name":"Thomas","id":"83141"}],"publication_status":"published","date_updated":"2023-10-16T07:13:41Z","page":"200","main_file_link":[{"url":"https://www.shaker.de/de/content/catalogue/index.asp?lang=de&ID=8&ISBN=978-3-8440-9240-0&search=yes"}],"_id":"48072","language":[{"iso":"ger"}],"user_id":"83141"},{"quality_controlled":"1","abstract":[{"lang":"eng","text":"<jats:p>Abstract. To increase the sustainability of forming processes such as punch bending, homogenization of the processed semi-finished product is an essential step in the manufacturing process. High-strength wire materials are usually available as strip material before being further processed in a forming process. For storage and transport, the material is coiled onto coils and transported to the customer. During the coiling process, residual stresses and plastic deformation are introduced into the wire. Thus, the final product quality is also influenced by the geometry of the coil. Straightening machines are used in production lines to compensate for these. Once a straightening machine has been set up, the settings for the roll positions are usually not changed. As a result, there is no reaction to material fluctuations, which means that the components to be produced do not meet the dimensional accuracy requirements. This leads to an increase in the rejection rate in manufacturing processes. To reduce the rejection rate, it is necessary to enable dynamic and flexible infeed of the straightening rollers. In this context, an innovative control concept with disturbance compensation was developed for the straightening process. The disturbance compensation uses a disturbance model that predicts the change in bending curvature over the coil radius. With this prediction, the straightening machine can be adjusted specifically. The roller positions are adjusted by a subordinate position control. The additional feedback from measured geometric product properties from the following punching-bending process enables the straightening machine to be adjusted even in the case of unforeseen fluctuations in the material properties. In this way, it is possible to react to any material fluctuations as required. This novel, demand-oriented adjustment of the straightening machine is expected to result in a high increase in the efficiency of the production process and a reduction of the rejection rate. </jats:p>"}],"citation":{"chicago":"Bathelt, Lukas, Eugen Djakow, Christian Henke, and Ansgar Trächtler. “Innovative Self-Learning Disturbance Compensation for Straightening Processes.” In <i>Materials Research Proceedings</i>.

Workpiece property-control permits the application-oriented and time-efficient production of components. In reverse flow forming, for example, a control of the microstructure profile is not yet part of the state of the art, in contrast to the geometry control. This is, due to several reasons, particularly challenging when forming seamless tubes made of metastable austenitic stainless AISI 304L steel. Inducing mechanical and/or thermal energy can cause a phase transformation from austenite to martensite within this steel. The resulting α’-martensite has different mechanical and micromagnetic properties, which can be advantageous depending on the application. For purposes of local property control, the resulting α’-martensite content should be measured and controlled online during the forming process. This paper presents results from the usage of a custom developed cryo-system and different application strategies to use liquid nitrogen as a coolant for local enhancement of the forming-temperature depending α’-martensite content. </jats:p>"}],"publication":"Materials Research Proceedings","user_id":"36287","_id":"44314","publisher":"Materials Research Forum LLC","status":"public","oa":"1","quality_controlled":"1","citation":{"short":"B.

Forming technology, which is confronted with new challenges regarding the quality of the workpieces, must also organise the individual processes more efficiently and at the same time more reliably in order to be able to guarantee good workpiece quality and at the same time to be able to produce economically. One way to meet these challenges is to carry out the forming processes in closed-loop control systems using softsensors. Despite the many potential applications of softsensors in the field of forming technology, there is still no definition of the term softsensor. This publication therefore proposes a definition of the softsensor based on the definition of a sensor and the distinction from the observer, which on the one hand is intended to stimulate scientific discourse and on the other hand is also intended to form the basis for further scientific work. Based on this definition, a wide variety of highly topical application examples of various softsensors in the field of forming technology are given.</jats:p>","lang":"eng"}],"publication":"Production Engineering","doi":"10.1007/s11740-023-01227-1","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s11740-023-01227-1","open_access":"1"}],"language":[{"iso":"eng"}],"date_updated":"2023-12-22T10:56:58Z","publication_status":"published","article_type":"original","year":"2023","title":"Softsensors: key component of property control in forming technology","author":[{"full_name":"Homberg, Werner","last_name":"Homberg","first_name":"Werner","id":"233"},{"id":"36287","full_name":"Arian, Bahman","first_name":"Bahman","last_name":"Arian"},{"last_name":"Arne","first_name":"Viktor","full_name":"Arne, Viktor"},{"id":"83141","full_name":"Borgert, Thomas","first_name":"Thomas","last_name":"Borgert"},{"last_name":"Brosius","first_name":"Alexander","full_name":"Brosius, Alexander"},{"full_name":"Groche, Peter","first_name":"Peter","last_name":"Groche"},{"full_name":"Hartmann, Christoph","first_name":"Christoph","last_name":"Hartmann"},{"full_name":"Kersting, Lukas","last_name":"Kersting","first_name":"Lukas"},{"last_name":"Laue","first_name":"Robert","full_name":"Laue, Robert"},{"first_name":"Juri","last_name":"Martschin","full_name":"Martschin, Juri"},{"first_name":"Thomas","last_name":"Meurer","full_name":"Meurer, Thomas"},{"last_name":"Spies","first_name":"Daniel","full_name":"Spies, Daniel"},{"last_name":"Tekkaya","first_name":"A.

In order to reduce global energy consumption in production and industry along with the associated CO2 emissions, existing resources must be used more efficiently. This includes the energy-efficient and comprehensive recycling of a wide range of metals. Especially for the production of aluminium, there is a large potential for saving energy using efficient recycling processes. With regard to the recycling of aluminium studies have shown that solid-state recycling processes are significantly more efficient considering the used energy and resources compared to the conventional, smelting-metallurgical recycling process. In this paper, the direct and energy-efficient friction-induced recycling process (FIRP) based on the conform process is further described and analysed in terms of the temperature-property relationships. For this purpose, the influence of the processing temperature on the microstructure and properties of the recycled semi-finished products is investigated using the toll system that enables an ECAP forming. Specific sections of the (in theory) infinite, recycled semi-finished product are taken and analysed at different process temperatures of the solid state recycling process. Based on these sections, the properties in terms of mechanical hardness, strength, ductility and grain size are analysed and a degressive relationship between process temperature and mechanical hardness up to a temperature of 270 °C can be shown. Applying the Hall-Petch relationship, it is analysed whether there is a correlation between the strength and the microstructure in the form of the grain size. </jats:p>","lang":"eng"}],"date_created":"2023-04-17T08:00:28Z","type":"conference","keyword":["Recycling","Aluminium","Friction-Induced","Energy Efficiency"],"department":[{"_id":"156"}],"year":"2023","title":"Analysis of temperature effect on strength and microstructure in friction induced recycling process (FIRP)","author":[{"full_name":"Borgert, Thomas","first_name":"Thomas","last_name":"Borgert","id":"83141"},{"id":"233","first_name":"Werner","last_name":"Homberg","full_name":"Homberg, Werner"}],"publication_identifier":{"issn":["2474-395X"]},"publication_status":"published","date_updated":"2023-04-26T13:26:22Z","language":[{"iso":"eng"}],"doi":"10.21741/9781644902479-211"},{"doi":"10.21741/9781644902479-208","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2023-04-27T10:30:44Z","author":[{"id":"64977","full_name":"Dahms, Frederik","last_name":"Dahms","first_name":"Frederik"},{"full_name":"Homberg, Werner","first_name":"Werner","last_name":"Homberg","id":"233"}],"publication_identifier":{"issn":["2474-395X"]},"title":"Energy and Resource-efficient Forming of Gas Cylinders by Friction-Spinning","year":"2023","department":[{"_id":"156"}],"type":"conference","date_created":"2023-04-17T07:40:54Z","related_material":{"link":[{"relation":"confirmation","url":"https://www.mrforum.com/product/9781644902479-208/"}]},"abstract":[{"text":"<jats:p>Abstract. Friction-spinning as an innovative incremental forming process enables large degrees of deformation in tube and sheet metal-forming due to a self-induced heat generation in the forming zone. This paper presents new process designs for energy and resource-efficient forming of gas cylinders by friction-spinning without the use of an external heat supply. The self-generated heat enables friction-spinning process to reduce the energy demand in the manufacture of gas cylinders, which are usually manufactured with external heat (mostly fossil fuels), by 95 %. Typical gas cylinder contours, such as flattened and spherical bottom ends and cylinder necks, are manufactured by friction-spinning of AW 6060 tubular profiles with specifically designed tool path strategies. It is shown that friction-spinning enables the manufacture of typical gas cylinder contours with sufficient wall thickness and the required gas tightness without the input of external heat. Thus, this process can contribute to an increase in the energy and resource efficiency of forming processes. </jats:p>","lang":"eng"}],"publication":"Materials Research Proceedings","user_id":"64977","publisher":"Materials Research Forum LLC","_id":"44035","conference":{"name":"ESAFORM 2023","start_date":"2023-04-19","location":"Krakau","end_date":"2023-04-21"},"status":"public","quality_controlled":"1","citation":{"apa":"Dahms, F., &#38; Homberg, W.

The combination of incremental sheet metal forming and high-speed forming offers new possibilities for flexible forming processes in the production of large sheet metal components of increased complexity with relatively low forming energies. In this paper, the general feasibility and process differences between the pulse-driven high-speed forming technologies of electrohydraulic and electromagnetic forming were investigated. An example component made of EN AW 6016 aluminum sheet metal was thus formed incrementally by both processes and the forming result evaluated by an optical 3D measurement system. For this purpose, a forming strategy for electromagnetic incremental forming (EMIF) was developed, tested and adapted to the electrohydraulic incremental forming process (EHIF). The discharge energy, the tool displacement and the pressure field of the forming zone were determined as relevant parameters for the definition of an adequate tool path strategy. It was found that the EHIF process is less affected by larger distances between the tool and the blank, while this is a critical variable for force application to the component during EMIF. On the other hand, the more uniform pressure distribution of the EMIF process is advantageous for forming large steady component areas. </jats:p>"}],"date_created":"2023-03-17T10:23:18Z","department":[{"_id":"156"}],"type":"conference","keyword":["Incremental Sheet Forming","Aluminium","High-Speed Forming"],"publication_identifier":{"issn":["2474-395X"]},"author":[{"full_name":"Holzmüller, Maik","last_name":"Holzmüller","first_name":"Maik","id":"82645"},{"first_name":"Maik","last_name":"Linnemann","full_name":"Linnemann, Maik"},{"full_name":"Homberg, Werner","first_name":"Werner","last_name":"Homberg","id":"233"},{"last_name":"Psyk","first_name":"Verena","full_name":"Psyk, Verena"},{"first_name":"Verena ","last_name":"Kräusel","full_name":"Kräusel, Verena "},{"full_name":"Kroos, Janika","first_name":"Janika","last_name":"Kroos"}],"title":"Proof of concept for incremental sheet metal forming by means of electromagnetic and electrohydraulic high-speed forming","year":"2023","intvolume":"        25","publication_status":"published","date_updated":"2023-05-02T11:40:24Z","language":[{"iso":"eng"}],"doi":"10.21741/9781644902417-2","citation":{"ama":"Holzmüller M, Linnemann M, Homberg W, Psyk V, Kräusel V, Kroos J.

Für kleine Losgrößen bietet sich hier insbesondere das Fertigungsverfahren des Drückwalzens an. Der konventionelle, industriell genutzte Drückwalzprozess stößt allerdings aufgrund der Prozesskomplexität hinsichtlich der Reproduzierbarkeit an seine Grenzen. Dies wird in der Praxis teilweise durch personengebundenes Erfahrungswissen kompensiert. Auch ist es nicht möglich, Bauteileigenschaften definiert einzustellen. Aus diesem Grund bietet der Einsatz einer neuartigen Eigenschaftsregelung Chancen zur Weiterentwicklung des Fertigungsprozesses und die Möglichkeit zur Prozessautomatisierung. Hier werden die Werkzeugbahnen abhängig einer Online-Eigenschaftsmessung über eine zusätzliche Reglerkaskade manipuliert. Die Entwicklung einer solchen Eigenschaftsregelung erfordert den Einsatz geeigneter, modellbasierter Entwurfsmethoden. In diesem Beitrag wird daher ein regelungstechnisches Systemmodell für das Drückwalzen metastabiler austenitischer Edelstähle vorgestellt. Das Simulationsmodell weist aufgrund seiner Echtzeitfähigkeit neben dem Einsatz als reines Entwurfsmodell weitere Nutzungsmöglichkeiten z.B. in Beobachtern auf und grenzt sich somit von domänenspezifischen Simulationstools wie der FEM ab.</jats:p>","lang":"eng"}],"date_created":"2023-05-02T09:35:01Z","department":[{"_id":"156"},{"_id":"241"},{"_id":"153"}],"keyword":["Electrical and Electronic Engineering","Computer Science Applications","Control and Systems Engineering"],"type":"journal_article","publication_identifier":{"issn":["0178-2312","2196-677X"]},"author":[{"full_name":"Kersting, Lukas","first_name":"Lukas","last_name":"Kersting"},{"id":"36287","last_name":"Arian","first_name":"Bahman","full_name":"Arian, Bahman"},{"first_name":"Julian","last_name":"Rozo Vasquez","full_name":"Rozo Vasquez, Julian"},{"id":"552","full_name":"Trächtler, Ansgar","first_name":"Ansgar","last_name":"Trächtler"},{"id":"233","last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner"},{"first_name":"Frank","last_name":"Walther","full_name":"Walther, Frank"}],"title":"Echtzeitfähige Modellierung eines innovativen Drückwalzprozesses für die eigenschaftsgeregelte Bauteilfertigung","year":"2023","intvolume":"        71","date_updated":"2023-09-25T10:08:25Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1515/auto-2022-0106","citation":{"ama":"Kersting L, Arian B, Rozo Vasquez J, Trächtler A, Homberg W, Walther F.

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. </jats:p>"}],"citation":{"apa":"Kersting, L., Arian, B., Rozo Vasquez, J., Trächtler, A., Homberg, W., &#38; Walther, F.
