Celebrating 50 Years of Forming Technology "Impulses and Innovations in Metal Forming
on September 8 and 9, 2022
Established in 1972 as the Chair for Forming Technologies, it evolved into one of Germany’s largest, internationally renowned forming technology institutes over the past 50 years, which is characterized by a broad-ranging field of research and a high level of training for engineers and young scientists. Together with research institutes and industrial partners from Germany and abroad, innovative basic and application-oriented research results were achieved, which often optimized industrial practice through technology transfer. Trends such as improved form and dimensional accuracy, the extension of forming limits, increasing product variance, or the environmentally conscious manufacturing and design of products were taken up and technological developments such as more precise analyses and calculation methods, more accurate measuring techniques, lightweight construction, new materials, digitalization, and artificial intelligence were applied. The thematically extended research assignment and the significant growth in staff members were taken into account by founding the IUL in 2004.
We look forward to celebrating the institute's anniversary with numerous companions in Dortmund in 2022.

Students meet IUL academic staff
For more than 10 years, the IUL has been doing research on innovative teaching and learning concepts for mechanical engineering within the scope of various (international) projects together with its partners. Nevertheless, during the Corona pandemic the IUL also had to find new concepts for well-established events and needed to digitize in-person courses and lectures at short notice. However, how successful were these concepts from the students' point of view?
In order to obtain this decisive feedback, Professor Tekkaya invited students and academic staff of the IUL’s forming technology lecture for a dialogue on May 27. Not only possible activities and jobs for students at the IUL, but also the challenges of digital examinations and ideas for improving teaching at the institute were discussed. The goal should be to combine the advantages of face-to-face learning and digital teaching. Through the direct exchange between students and teaching staff, problems in the implementation of digital teaching were identified and helpful impulses for teaching after Corona could be taken up. In addition, the meeting laid the foundation for an intensified collaboration between students and scientists in basic and application-oriented research at the IUL.
Digital lecture series for forming technology
On April 22, 2021, the first digital edition of the “Lecture Series Forming Technology” will take place in the 2021 summer semester. The industrial lectures offer application-related reports from industrial practice. They are organized by the IUL in order to promote the direct exchange between academia and industry in teaching and to allow both sides to benefit from the advantages of direct encounter.
Registration for the lectures is required:

New KORESIL project launched: Concepts for the resource-efficient and safe production of lightweight structures
On February 15, 2021, under the direction of Prof. Dr.-Ing. habil. Maik Gude from the Institute of Lightweight Structures and Polymer Technology (ILK) at the TU Dresden, the research and development project "Concepts for the resource-efficient and safe production of lightweight structures (KORESIL)" was launched. The joint project of ILK (Dresden), LWF (Paderborn), IART (Freiberg), iwb (Munich) and IUL (Dortmund) focuses on socio-technical solutions for process chains with closed material cycles. In particular, production aids such as online Life Cycle Assessment (LCA), Augmented Reality (AR) and collaborating robots (cobotics) are the focus of the work, which aims to achieve resource-efficient production of lightweight structures and safe, attractive workplace design.
IUL Keynote presentation of the Techtank Conference 2020 is now availabl
In 2020, the (digital) Techtank conference was hold on the topic of “Flexible Production, with focus on forming and stamping”. In his keynote presentation, Prof. Tekkaya talked about “New Technologies at the IUL” to point out the incredible flexibility in forming.
“Techtank Conference is organised by Techtank in collaboration with the Swedish application center Stamping and Forming Center of Excellence. The Conference has been organized since 2015, and is an annual meeting place for manufacturing and engineering companies, research institutes and other organizations that want to keep up to date with current trends in innovative manufacturing for industrial use, with focus on forming and stamping.” (Source: https://www.techtankconference.se)

New project on prediction of geometry changes during spring production
On December 1, 2020 the new project “Development of a model to predict geometry changes in spring manufacturing based on plasticity theory considering heat treatment“. The research project is funded by the FSV and the AiF. A virtual kick-off meeting with 30 representatives of the project partners from the spring industry took place on January 28. Based on material characterization and experimental investigations of the elementary process steps of winding, heat treatment and pre-setting, an analytical process model of the entire manufacturing process is being developed in the project. The model is intended to enable the determination of residual stresses and geometry changes during the production of helical compression springs, thus facilitating the currently largely experience-based adjustment of automatic winding machines. In addition, a better understanding of the individual manufacturing steps and their influence on the product properties is to be gained.

First digital lecture delivered from the experimental area at the IUL
On December 17, 2020, the hall lecture at the IUL was held digitally for the first time. This special lecture is held every winter semester as part of the lectures “Fundamentals in Forming Technology” and “Forming Technologies II” in order to provide students with a practical insight into the experimental area. After a short welcome and introduction to the institute by Prof. Tekkaya, the approximately 100 students attending the Zoom meeting were able to participate in a virtual tour through the hall, while at the same time experiments on four experimental stands were streamed live. IUL staff members conducted experiments on parameter identification, rotary draw bending, incremental sheet forming, and adiabatic blanking. The students had the opportunity to ask questions and comment on what they had seen at any time.
DFG approves second funding period of TRR 188
In the SFB / TRR188 “Damage-Controlled Forming Processes”, research on the paradigm shift in forming technology can be continued until 2024.
The German Research Foundation (DFG) has decided to continue funding the Collaborative Research Center Transregio (TRR) 188. For the second funding period until the end of 2024, 11.4 million euros were approved. As initiator and spokesperson of the Collaborative Research Center, Prof. A. E. Tekkaya will regularly hand over the management to Prof. G. Hirt from the IBF at RWTH Aachen University starting from January 2021. Other institutions involved in the second funding period are the “Max-Planck-Institut für Eisenforschung” in Düsseldorf and the Institute for Applied Materials – Section “Materials and Biomechanics” at KIT in Karlsruhe.
Internal material damage occurs when metal is formed. Under the guiding principle that damage is controllable and not a failure, the CRC/TRR 188 investigates how this affects the product properties. Within the interdisciplinary cooperation between forming technology, materials science, materials testing technology, and mechanics, it is be shown that the product design does not have to take the nominal properties into account, but the actual production-induced product properties, including damage. The aim is to indicate the degree of damage to a component quantitatively, to control it, and to specifically adjust it along the process chain. This enables the manufacture of innovative lightweight products with tailored and guaranteed performance.
