--- _id: '64129' abstract: - lang: eng text: Selecting scan angles such that surface segments are aligned with straight X-ray paths (i.e., rays are tangential to the surface and therefore perpendicular to the local surface normal) is known to produce sharper transitions of those surface segments in the reconstructed volume. This enhances dimensional accuracy in sparse-view computed tomography (CT). However, existing approaches offer no direct means to exploit this criterion for automatic scan-angle optimization. We propose a method that uses a virtual representation of the CT setup, including an STL surface model of the inspected part, to automatically identify taskspecific scan angles. Using elementary vector calculus, the algorithm determines projection directions that generate tangential X-rays for targeted surface segments. To support different levels of geometric complexity, we introduce two variants of the angle-selection procedure. The methods were experimentally validated on two objects with distinct absorption and geometric characteristics. For a steel gauge block, employing the minimum number of task-specific projections required for surface-data completeness substantially outperformed a conventional high-projection scan. For a geometrically more complex test object, surface-related errors were still reduced within the region of interest. The proposed approach – particularly suited for flat surface structures and not accounting for image-degrading factors other than cone-beam artifacts – shows promise for high-throughput dimensional metrology of mono-material parts. author: - first_name: Lorenz full_name: Butzhammer, Lorenz last_name: Butzhammer - first_name: Matthias Robert Oskar full_name: Braun, Matthias Robert Oskar last_name: Braun - first_name: Colin full_name: Herath, Colin last_name: Herath - first_name: Tino full_name: Hausotte, Tino last_name: Hausotte citation: ama: 'Butzhammer L, Braun MRO, Herath C, Hausotte T.

To maintain high accuracy when deviating from the established circular scan trajectory, trajectory calibration methods using multi-sphere reference objects with known marker positions are commonly employed. These multi-sphere objects can either be scanned together with the measurement object (online trajectory calibration) or in a separate scan (offline trajectory calibration). While offline calibration increases machine time, it generally results in higher scan quality. However, a sufficient pose repeatability is necessary to ensure comparable or even superior accuracy to online calibration. In this contribution, we present a straightforward procedure to compare both types of trajectory calibration in a way that the differences of the results can directly be traced back to the influence of the pose repeatability. The multi-sphere reference object is not only used for trajectory calibration, but simultaneously as a measurement object for repeated measurements. The methodology is tested on both a twin robotic CT system and a conventional CT system that is additionally equipped with a hexapod manipulator for adaptive object tilting. Results showed, independent from the type of trajectory calibration, systematic measurement errors in the order of 10−5–10−4 of measured sphere distances and sphericity values below 50 \r\n \ \r\n \r\n \r\n \r\n \ μ\r\n \r\n \ \r\n m\r\n \r\n \ \r\n \r\n . For sphere distances, random errors were increased by a factor of 5 due to the offline trajectory calibration, but were still low (\r\n \ \r\n \r\n \r\n \r\n \ <\r\n \r\n \ \r\n 1\r\n \ \r\n \r\n \r\n μ\r\n \ \r\n \r\n \ m\r\n \r\n \ \r\n \r\n ) in comparison to systematic errors and the spread of different measurement features. Overall, both investigated systems demonstrated sufficient positioning repeatability for offline trajectory calibration. The method is in general also applicable to any other types of manipulator systems used for CT devices. It provides a workflow for the decision which type of trajectory calibration is preferable for a given CT system." article_number: '025401' author: - first_name: Lorenz full_name: Butzhammer, Lorenz last_name: Butzhammer - first_name: Niklas full_name: Handke, Niklas last_name: Handke - first_name: Simon full_name: Wittl, Simon last_name: Wittl - first_name: Gabriel full_name: Herl, Gabriel last_name: Herl - first_name: Tino full_name: Hausotte, Tino last_name: Hausotte citation: ama: Butzhammer L, Handke N, Wittl S, Herl G, Hausotte T.

Insbesondere Mehrfachanordnungen von Clinchpunkten wurden bisher nur selten untersucht. In der vorliegenden Arbeit wird die Zuverlässigkeit von gefügten Proben mit einer Mehrfachanordnung von Clinchpunkten unter zyklischer Beanspruchung untersucht. Ziel ist es, die Wechselwirkung benachbarter Clinchpunkte und deren Einfluss auf die Ermüdungslebensdauer zu untersuchen. Dazu wurden Proben mit variierenden Fügepunktabständen hergestellt und in Versuchsreihen zyklisch belastet. Die Resultate zeigen, dass die räumliche Anordnung der Clinchpunkte das Ermüdungsverhalten beeinflusst. Es wurde festgestellt, dass bei Mehrfachanordnungen sowohl der Fügepunktabstand als auch der Abstand der Fügepunkte zum Bauteilrand in Belastungsrichtung einen Einflussfaktor darstellen. Die vorliegende Arbeit leistet somit einen Beitrag zur Lebensdauervorhersage gefügter Strukturen und bildet eine Grundlage für weiterführende Untersuchungen zu Gestaltungsempfehlungen. author: - first_name: Eugen full_name: Wolf, Eugen last_name: Wolf - first_name: Katharina full_name: Hollmer, Katharina last_name: Hollmer - first_name: Martina full_name: Zimmermann, Martina last_name: Zimmermann - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Wolf E, Hollmer K, Zimmermann M, Brosius A.

The primary objective is to assess the influence of the specimen stiffness with an arrangement of clinched joints. The specimen stiffness depends on several variables. In addition to the material selection, the specific choice of geometry and the design of the clinched joints must also be taken into account. A number of experiments was conducted to investigate the failure behavior of specimens with an arrangement of three clinched joints under shear tensile loading. These configurations were subjected to shear tensile tests, with force displacement curves recorded for each specimen to provide a detailed characterization of their structural response. The stiffness is modified by altering the specimen width, which has marginal impact on the maximum force. The experimental findings indicate that reducing the specimen stiffness results in a shift in the type of stress, with the failure behavior becoming increasingly influenced by bending stress. These results offer important insights for the design of clinched joint assemblies, indicating that it is feasible to achieve the desired properties by changing the specimen stiffness. article_number: '01080' author: - first_name: Eugen full_name: Wolf, Eugen last_name: Wolf - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Wolf E, Brosius A.

The primary objective is to assess the influence of the joining direction and the spatial arrangement of clinched joints on their mechanical performance. A number of experiments was conducted, focusing on three clinched joints arranged in different configurations, each varying in terms of joining direction and spacing. These configurations were subjected to shear tensile tests, with force-displacement curves recorded for each sample to provide a detailed characterization of their structural response. The experimental findings indicate that the specific arrangement of the clinched joints, in terms of joining direction, has a marginal impact on the overall failure behavior. This suggests that intricate modifications to the joining direction are unnecessary to achieve improved mechanical performance in such applications. These results offer valuable insights for the design of clinched joint assemblies, indicating that simplified joining strategies may suffice without compromising structural integrity under shear loading. author: - first_name: Eugen full_name: Wolf, Eugen last_name: Wolf - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Wolf E, Brosius A.

This hypothesis is tested using a Reuleaux triangle joint geometry. A tool design is carried out, followed by a numerical sensitivity analysis of the tool geometry. Initial tools were manufactured for experimental investigations and then adapted based on the findings of the sensitivity analysis. The joints are characterized by micrographs, 3D scans, shear tensile tests, head tensile tests and three-point bending tests and compared with a round geometry. The analysis confirms the hypothesis. Thus, joints with adaptable properties can be produced with one tool set. author: - first_name: Christian full_name: Steinfelder, Christian last_name: Steinfelder - first_name: Clemens full_name: Acksteiner, Clemens last_name: Acksteiner - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: Steinfelder C, Acksteiner C, Brosius A.

As part of the development of a method for ensuring the versatility of clinching, an additional rotational movement of the punch was introduced as a control variable to influence friction in the mechanical joining process. The effect of rotational superimposition on the force-displacement curve of the clinching processes was investigated using four test variants with different kinematics. The primary objective was to evaluate the binding mechanisms that maintain the integrity of the clinched joint. To evaluate the force closure of the resulting joint, two testing methods were employed throughout the course of the research, non-destructive resistance measurement using four-wire sensing method and destructive torsion testing. A crucial factor influencing the efficacy of the process is surface cleanliness, as contaminants between joining partners can impede the effectiveness of the clinched joint. Therefore, all specimens were meticulously cleaned prior to experimentation. This method exhibits promising potential in creating clinched joints that align with the demands of flexible manufacturing environments. article_number: '01086' author: - first_name: Stephan full_name: Lüder, Stephan last_name: Lüder - first_name: Eugen full_name: Wolf, Eugen last_name: Wolf - first_name: Hans Christian full_name: Schmale, Hans Christian last_name: Schmale - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Lüder S, Wolf E, Schmale HC, Brosius A.

In this context, mechanical joining technology clinching offers a fast and energy-efficient procedure for assembling sheet metals, being a proper alternative to established joining methods, such as spot welding. However, the design of clinch points is a challenge, which is partly supported by numerical or data-based approaches for optimal tool dimensions assuring proper joint characteristics. While this is usually done for an ideal environment, real joining processes are characterized by multiple inevitably varying parameters, e.g. of the material, which have a significant impact on the quality of clinch points. Therefore, this contribution addresses the current gap by analyzing the effect of parameter variations or uncertainties on the resulting joint characteristics and studying the impact of the nominal tool design. Thus, an efficient meta-model-based variation simulation procedure is proposed and used for analyzing the effect of different tool design configurations and variation scenarios. Based on the results, it was found that varying process parameters have a strong impact on the resulting joint characteristics, whereby the effect significantly depends on the nominal tool design. This reveals the potential for a robust tool design and implies that the nominal tool design and the tolerancing of parameters should be done simultaneously for a reliable virtual joining point design without extensive iterations and physical tests. author: - first_name: C full_name: Zirngibl, C last_name: Zirngibl - first_name: S full_name: Goetz, S last_name: Goetz - first_name: S full_name: Wartzack, S last_name: Wartzack citation: ama: 'Zirngibl C, Goetz S, Wartzack S.

For this purpose, three series of tests were performed. In the first series of tests, the influence of heat treatment up to 340 °C on the mechanical properties of an age-hardenable AlMgSi alloy was investigated. Holding time and temperature were varied and the material strength was evaluated by tensile and hardness tests. Two strength-increasing and two strength-reducing heat treatment parameters were identified. In the second series of tests, selected heat treatment parameters were applied to a larger number of specimens and the joint strength was investigated by shear and head tensile tests. In the shear tensile test, mainly the properties of the punch-side material have an influence on the resulting joint strength. A change in strength of the die-side material can be neglected. In contrast, the properties of both sheets are important in the head tensile test. The strength of the joint will only increase if the strength of both sheets is increased. In general, a strength increasing heat treatment resulted in higher joint strength. In the third series of tests, the factor of punch displacement was considered, which was demonstrated to directly influence the formation of the clinched joint geometry. article_number: '100263' author: - first_name: Christian full_name: Steinfelder, Christian last_name: Steinfelder - first_name: Dennis full_name: Rempel, Dennis last_name: Rempel - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: Steinfelder C, Rempel D, Brosius A.

An einer ausgewählten Fügeaufgabe werden im Stufenversuch die gegenseitigen Abhängigkeiten der einzelnen Einflussgrößen sowie des Wärmebehandlungszustands aufgezeigt. Dabei wird zwischen den Bindemechanismen Formschluss und Kraftschluss unterschieden. Die Formschlusskomponente wird anhand der geometrischen Kenngrößen wie Bodendicke, Halsdicke und Hinterschnitt in Mikroskopieuntersuchungen an Schliffbildern und den mechanischen Eigenschaften der Fügeverbindung untersucht, die im Scherzug- und Kopfzugversuch bestimmt werden. Dazu erfolgt zudem die Charakterisierung der Versagensbilder. Zur Quantifizierung der Kraftschlusskomponente der Fügeverbindung werden das Losbrechmoment im Torsionsversuch und der elektrische Widerstand mittels Vier-Leiter-Methode ermittelt und korreliert. author: - first_name: Stephan full_name: Lüder, Stephan id: '104468' last_name: Lüder orcid: https://orcid.org/0000-0002-9086-3031 - first_name: Jan full_name: Kalich, Jan last_name: Kalich - first_name: Hannes full_name: Oesterle, Hannes last_name: Oesterle - first_name: Hans Christian full_name: Schmale, Hans Christian last_name: Schmale citation: ama: 'Lüder S, Kalich J, Oesterle H, Schmale HC.

The miniaturisation of components leads to new demands on measurement systems. One of these is the resolution. As a volumetric analysis method and method of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has the ability to measure geometrical features and their corresponding dimensions without destroying them and can therefore be used for quality assurance. However, the concept of resolution is not trivial for XCT and has not yet been finally clarified. In particular, the interface structural resolution, the detectability of two surfaces facing each other after surface segmentation, faces a lack of a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based XCT investigations of a method to determine this type of resolution are presented in this article using the geometry of a test specimen that contains several radially\r\narranged holes of the same size. The borehole diameters correspond to the distance between the holes to investigate the resolvability of surfaces and interfaces. The evaluation is based on mean and extreme values of grey value\r\nprofiles between the individual boreholes of the reconstructed volume. It is shown that the geometrical detectability of the test specimen surface and interface can be extended by a reasonable choice of the threshold value for\r\nsurface segmentation within a defined interval. With regard to the resolving capability, a distinction is made between assured detectability and possible detectability, as well as the threshold value used when using the ISO50\r\nthreshold for surface segmentation and measurement chain completion.
