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. article_number: '100113' author: - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: M. full_name: Merklein, M. last_name: Merklein - first_name: A. full_name: Brosius, A. last_name: Brosius - first_name: D. full_name: Drummer, D. last_name: Drummer - first_name: L. full_name: Fratini, L. last_name: Fratini - first_name: U. full_name: Füssel, U. last_name: Füssel - first_name: M. full_name: Gude, M. last_name: Gude - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: P.A.F. full_name: Martins, P.A.F. last_name: Martins - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: M. full_name: Lechner, M. last_name: Lechner - first_name: R. full_name: Kupfer, R. last_name: Kupfer - first_name: B. full_name: Gröger, B. last_name: Gröger - first_name: Daxin full_name: Han, Daxin id: '36544' last_name: Han - first_name: J. full_name: Kalich, J. last_name: Kalich - first_name: Fabian full_name: Kappe, Fabian id: '66459' last_name: Kappe - first_name: T. full_name: Kleffel, T. last_name: Kleffel - first_name: D. full_name: Köhler, D. last_name: Köhler - first_name: C.-M. full_name: Kuball, C.-M. last_name: Kuball - first_name: J. full_name: Popp, J. last_name: Popp - first_name: D. full_name: Römisch, D. last_name: Römisch - first_name: J. full_name: Troschitz, J. last_name: Troschitz - first_name: Christian full_name: Wischer, Christian id: '72219' last_name: Wischer - first_name: S. full_name: Wituschek, S. last_name: Wituschek - first_name: M. full_name: Wolf, M. last_name: Wolf citation: ama: Meschut G, Merklein M, Brosius A, et al.

It is characterized by the utilization of universal tooling geometries and quite low forming forces. The process has a high potential to reduce material waste, to extend the forming limits and to achieve more complex geometries as well as favorable part properties [1]. Current research work at the Chair of Forming Technology (LUF) is focused on innovative flow-turning processes that have a high potential for producing flat components with excellent geometrical and mechanical properties while keeping process times short [2]. In combination with process-integrated local heat treatment, the new spinning process is predestined for the efficient forming of ultra-high-strength steel or tailored materials. Due to the desired field of food industry only food-safe materials such as special stainless steels are being investigated. This paper presents an innovative machine layout as well as an adequate process design for the production of high-performance circular knives with optimized mechanical hardness. In this context, particular attention is paid to various areas of temperature control as well as process-related challenges during the process. author: - first_name: David full_name: Engemann, David id: '51720' last_name: Engemann - first_name: Werner full_name: Homberg, Werner last_name: Homberg citation: ama: Engemann D, Homberg W.

In addition to experimental investigations, numerical studies are indispensable tools for its development. Therefore, this paper includes an analysis of boundary conditions for the spatial discretization and mesh modeling techniques, the material modeling, the contact and friction modeling, and the thermal boundary conditions for the finite element (FE) modeling of this joining process. For these investigations, two FE models corresponding to the two process steps were set up and compared with the two related processes of friction stir welding and friction drilling. Regarding the spatial discretization, the Lagrangian approach is not sufficient to represent the deformation that occurs. The Johnson-Cook model is well suited as a material model. The modeling of the contact detection and friction are important research subjects. Coulomb’s law of friction is not adequate to account for the complex friction phenomena of the adaptive joining process. The thermal boundary conditions play a decisive role in heat generation and thus in the material flow of the process. It is advisable to use temperature-dependent parameters and to investigate in detail the influence of radiation in the entire process. article_number: '869' author: - first_name: Annika full_name: Oesterwinter, Annika id: '44917' last_name: Oesterwinter - first_name: Christian full_name: Wischer, Christian id: '72219' last_name: Wischer - first_name: Werner full_name: Homberg, Werner last_name: Homberg citation: ama: Oesterwinter A, Wischer C, Homberg W.

They permit materials of different types to be joined in a way that is suitable for the loads involved. These processes reach their limits, however, as soon as the boundary conditions change. In most cases, these elements are specially adapted to the joining point and cannot be used universally. Changes require cost-intensive adaptation of both the element and the process control, thus making production more complex. This results in high costs due to the increased number of auxiliary joining element variants required and reduces the economic efficiency of mechanical joining. One approach to overcoming this issue is the use of adaptive auxiliary joining elements formed by friction spinning. This article presents the current state of research on pre-hole-free joining with adaptive joining elements. The overall process chain is illustrated, explained and analyzed. Special attention is paid to demonstrating the feasibility of pre-hole-free joining with adaptive joining elements. The chosen mechanical parameters are subsequently listed. Finally, a comprehensive outlook of the future development potential is derived. article_type: original author: - first_name: Christian full_name: Wischer, Christian last_name: Wischer - first_name: Werner full_name: Homberg, Werner last_name: Homberg citation: ama: Wischer C, Homberg W.

Incremental strategies overcome this limit by using a sequence of local deformations to form larger component areas gradually. Hence, the technological potential of high-speed forming can be exploited for large-area components too. The target-oriented process design of such incremental forming operations requires a deep understanding of the underlying electromagnetic and electrohydraulic forming processes. This article therefore analyzes and compares the influence of fundamental process parameters on the acting loads, the resulting course of deformation, and the forming result for both technologies via experimental and numerical investigations. Specifically, it is shown that for the EHF process considered, the electrode distance and the discharge energy have a significant influence on the resulting forming depth. In the EHF process, the largest forming depth is achieved directly below the electrodes, while the pressure distribution in the EMF depends on the fieldshaper used. The energy requirement for the EHF process is comparatively low, while significantly higher forming speeds are achieved with the EMF process. author: - first_name: Thomas full_name: Heggemann, Thomas id: '9360' last_name: Heggemann - first_name: Verena full_name: Psyk, Verena last_name: Psyk - first_name: Annika full_name: Oesterwinter, Annika id: '44917' last_name: Oesterwinter - first_name: Maik full_name: Linnemann, Maik last_name: Linnemann - first_name: Verena full_name: Kräusel, Verena last_name: Kräusel - first_name: Werner full_name: Homberg, Werner last_name: Homberg citation: ama: Heggemann T, Psyk V, Oesterwinter A, Linnemann M, Kräusel V, Homberg W.

This paper presents a new tool and process design with a driven tool for the targeted adjustment of residual stress distributions in the friction-spinning process. Locally adapted residual stress depth distributions are intended to improve the functionality of the friction-spinning workpieces, e.g. by delaying failure or triggering it in a defined way. The new process designs with the driven tool and a subsequent flow-forming operation are investigated regarding the influence on the residual stress depth distributions compared to those of standard friction-spinning process. Residual stress depth distributions are measured with the incremental hole-drilling method. The workpieces (tubular part with a flange) are manufactured using heat-treatable 3.3206 (EN-AW 6060 T6) tubular profiles. It is shown that the residual stress depth distributions change significantly due to the new process designs, which offers new potentials for the targeted adjustment of residual stresses that serve to improve the workpiece properties. author: - first_name: Frederik full_name: Dahms, Frederik id: '64977' last_name: Dahms - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg citation: ama: 'Dahms F, Homberg W.

The complex thermomechanical conditions generate non-uniform residual stress distributions. In order to specifically adjust these residual stress distributions, the influence of different process parameters on residual stress distributions in flanges formed by the friction-spinning of tubes is investigated using the design of experiments (DoE) method. The feed rate with an effect of −156 MPa/mm is the dominating control parameter for residual stress depth distribution in steel flange forming, whereas the rotation speed of the workpiece with an effect of 18 MPa/mm dominates the gradient of residual stress generation in the aluminium flange-forming process. A run-to-run predictive control system for the specific adjustment of residual stress distributions is proposed and validated. The predictive model provides an initial solution in the form of a parameter set, and the controlled feedback iteratively approaches the target value with new parameter sets recalculated on the basis of the deviation of the previous run. Residual stress measurements are carried out using the hole-drilling method and X-ray diffraction by the cosα-method. article_number: '158' author: - first_name: Frederik full_name: Dahms, Frederik id: '64977' last_name: Dahms - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg citation: ama: 'Dahms F, Homberg W.

For storage and transport of the semi-finished wire to the customer, the material is wound onto coils. The manufacturing and coiling process introduces plastic deformations into the wire, which lead to undesirable residual stresses and wire curvature of the semi-finished product. These residual stresses and curvatures cause variations in the material properties of the semi-finished product, which have a negative impact on the subsequent product quality. Straightening machines are used to compensate the residual stresses and the curvature in the wire. At the beginning of the straightening process, the straightening machines must be set up in such a way that residual stresses and curvatures are optimally compensated. This setup process is usually a manual and iterative process, where a lot of material is wasted until the optimal settings for the straightening machine are found.In order to reduce the amount of material waste, the operator must be supported in the setup process. In this context, a new and innovative setup assistance system was developed to support the operator during the setup process. The setup assistant system automatically detects the wire curvature by means of an optical measuring system. Based on the optically detected measuring points, the wire curvature is determined by a robust calculation algorithm. Based on a database built up through the carried out experimental and numerical research work, the optimum setting parameters for the straightening machine are suggested to the operator without lengthy trial and error. After confirmation by the operator, the roller settings are automatically adjusted by the mechatronic straightening machine. With the presented method, the conventional iterative setup procedure can be made more resource-efficient and a high straightening quality can be reproducibly achieved.

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." author: - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Hanigah full_name: Kanagarajah, Hanigah last_name: Kanagarajah - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: Rozo Vasquez J, Kanagarajah H, Arian B, et al.

Especially with small batch size, the incremental flow forming processes can be advantageous. 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. author: - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Julian Rozo full_name: Vasquez, Julian Rozo last_name: Vasquez - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: Kersting L, Arian B, Vasquez JR, Trächtler A, Homberg W, Walther F.
