  text: <jats:p>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.</jats:p>

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Industrial x-ray
    computed tomography (CT) systems with high geometric flexibility are increasingly
    utilized for large-scale measurement objects or challenging measurement tasks.
    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<jats:sup>−5</jats:sup>–10<jats:sup>−4</jats:sup>
    of measured sphere distances and sphericity values below 50 <jats:inline-formula>\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.</jats:p>"

  text: Abstract. Mechanical joints are traditionally analyzed through destructive
    micrograph analysis, which may compromise internal geometry and morphology, as
    evidenced by radial cracks in semi-tubular self-pierce riveting. In contrast,
    industrial X-ray computed tomography (XCT) offers a non-destructive method for
    component diagnosis, providing volumetric insights without damaging the sample
    and enabling dimensional measurement. The DFG-funded Collaborative Research Center
    TRR 285 is exploring XCT's application in assessing mechanical joinability across
    various joining processes and materials, particularly in multi-material systems
    like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material
    compositions, leading to artifacts that complicate interface detection. This research
    aims to validate XCT for joint investigations, yielding quantitative characteristics
    that surpass those from traditional micrograph analysis.

  text: Monitoring force-displacement or force-time curves is a widely used quality
    control technique in the field of mechanical joining. For online monitoring of
    self-piercing riveting, envelope curves are often used to define a tolerance zone
    for the measured setting force. However, the measurement uncertainty is typically
    not considered and the force curve of a joint can be wrongly rated as non-conform
    due to measurement errors and noise. In this article, we present a method for
    dynamical online filtering and uncertainty determination for noisy force curves
    using two types of Bayesian filters. The methodology is based on a Bayesian probability
    framework using a priori information for the process curve and sensor noise. To
    investigate the general feasibility of the method, force measurements with different
    noise levels are simulated and processed. The conformity is further assessed taking
    the uncertainty of the filtered signal into account. The results show that the
    Bayes filter technique is principally able to reduce noise for well-known characteristics
    of the process curve and sensor noise. Advantages over common filtering techniques,
    especially for experimental conditions with less known characteristics, are still
    to be verified. The methodology could be used in future for closed-loop controls
    to adapt process parameters dynamically. </jats:p>

  text: "Abstract. 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. "

  text: Unter dem Begriff der Auflösung wird für gewöhnlich das kleinste messbare
    Merkmal eines Messsystems verstanden. In der dimensionellen Computertomografie
    hingegen haben sich in den vergangenen Jahren mehrere Auflösungskonzepte etabliert,
    die aufgrund der fehlenden Normung zueinander im Kontrast stehen. In diesem Beitrag
    werden die drei häufigsten Konzepte, die Voxelgröße, die Ortsauflösung und die
    metrologische Strukturauflösung in Kürze vorgestellt. Anschließend wird eine Abgrenzung
    zwischen den Konzepten getroffen und ein Integration der bestehenden Konzepte
    in ein gemeinsames Amplituden-Wellenlängen Diagramm diskutiert.

  text: Surface determination is an essential step of the measurement process in industrial
    X-ray computed tomography (XCT). The starting point of the surface determination
    process step is a single grey value threshold within a voxel volume in conventional
    surface determination methods. However, this value is not always found in the
    reconstructed volume in the local environment of the surface of the measurement
    object due to various artefacts, so that none or incorrect surfaces are determined.
    In order to find surfaces independently of a single grey value, a three-dimensional
    approach of the initial contour determination based on a Prewitt edge detection
    algorithm is presented in this work. This method is applied to different test
    specimens and specimen compositions which, due to their material or material constellation,
    their geometric properties with regard to surfaces and interfaces as well as their
    calibrated size and length dimensions, embody relevant properties in the examination
    of joining connections. It is shown that by using the surface determination method
    in the measurement process, both a higher metrological structure resolution and
    interface structure resolution can be achieved. Surface artefacts can be reduced
    by the application and it is also an approach to improved surface finding for
    the multi-material components that are challenging for XCT.

  text: This article presents the application and evaluation of a cantilever with
    integrated sensing and actuation as part of an atomic force microscope (AFM) with
    an adjustable probe direction, which is integrated into a nano measuring machine
    (NMM-1). The AFM, which is operated in closed-loop intermittent contact mode,
    is based on two rotational axes that enable the adjustment of the probe direction
    to cover a complete hemisphere. The axes greatly enlarge the metrology frame of
    the measuring system by materials with a comparatively high coefficient of thermal
    expansion, which ultimately limits the achievable measurement uncertainty of the
    measuring system. Thus, to reduce the thermal sensitivity of the system, the redesign
    of the rotational kinematics is mandatory. However, in this article, some preliminary
    investigations on the application of a self-sensing cantilever with an integrated
    micro heater for its stimulation will be presented. In previous investigations,
    a piezoelectric actuator has been applied to stimulate the cantilever. However,
    the removal of the piezoelectric actuator, which is enabled by the application
    of a cantilever with an integrated micro heater, promises an essential simplification
    of the sensor holder. Thus, in the future it might be possible to use materials
    with a low coefficient of thermal expansion, which are often difficult to machine
    and therefore only allow for rather simple geometries. Furthermore, because of
    the creepage of piezoelectric actuators, their removal from the metrology frame
    might lead to improved metrological characteristics. As will be shown, there are
    no significant differences between the two modes of actuation. Therefore, the
    redesigned rotational system will be based on the cantilever with integrated sensing
    and actuation.

  text: "Destructive micrograph analysis (MA) is the standard method for the assessment
    of clinched joints. However, during the joint preparation for the MA, geometric
    features of the joint can change due to elastic effects and closing cracks. X-ray
    computed tomography (CT) is a promising alternative to investigate the joint non-destructively.
    However, if the\r\nmaterial properties of similar joining partners are the same,
    the CT is not able to correctly resolve surfaces in the joint that are close to
    or pressing onto each other. These surfaces are relevant for the determination
    of characteristic dimensions such as neck thickness and undercut. By placing a
    thin, highly radiopaque tin layer between the joining partners, the interfacial
    area in the reconstructed volume can be highlighted. In this work, a method for
    the localisation of the tin layer inside the joint as well as threshold value
    procedures for the outer joint contour in cross section images are investigated.
    The measured characteristic dimensions are compared with measured values from
    MA of the same samples and of samples without tin layer. In addition, possible
    effects of the tin layer on the joining point\r\ncharacteristics as well as problems
    of the MA are discussed."

  text: 'Clinching as a mechanical joining technique allows a fast and reliable joining
    of metal sheets in large-scale production. An efficient design and dimensioning
    of clinched joints requires a holistic understanding of the material, the joining
    process and the resulting properties of the joint. In this paper, the process
    chain for clinching metal sheets is described and experimental techniques are
    proposed to analyze the process-microstructure-property relationships from the
    sheet metal to the joined structure. At the example of clinching aluminum EN AW
    6014, characterization methods are applied and discussed for the following characteristics:
    the mechanical properties of the sheet materials, the tribological behavior in
    the joining system, the joining process and the resulting material structure,
    the load-bearing behavior of the joint, the damage and degradation as well as
    the service life and crack growth behavior. The compilation of the characterization
    methods gives an overview on the advantages and weaknesses of the methods and
    the multiple interactions of material, process and properties during clinching.
    In addition, the results of the analyses on EN AW 6014 can be applied for parameterization
    and validation of simulations.'

  text: In industrial x-ray computed tomography (CT), the application of more complex
    scan paths in comparison to the typical circular trajectory (${360}^{\circ}$ rotation
    of the measurement object) can extend the potential of CT. One way to enable such
    3D scan trajectories is to use a 6-degrees-of-freedom (DOF) object manipulator
    system. In our case, a hexapod is mounted on top of the rotary table of a commercial
    CT scanner. This allows for adaptive tilting of the measurement object during
    the scan. For high accuracy, the geometry calibration of such setups is typically
    done using the x-ray projections of a calibrated multi-sphere object. Contrary
    to this, here, we demonstrate a procedure that is based on only a single sphere
    and can therefore experimentally be implemented with low effort. Using the intrinsic
    geometry parameters of the CT device as prior information, the hexapod coordinate
    system with respect to the CT machine coordinate system is determined by means
    of a one-step optimization approach. The resulting parameters are used to calculate
    projection matrices that enable the volume reconstruction for 3D scan trajectories.
    The method is validated using simulated x-ray images and experimental investigations
    including dimensional measurements. For the used setup, geometric measurement
    results for 3D scan trajectories that are calibrated with the presented method
    show in sum increased errors compared to the circular scans. A limited pose accuracy
    of the manipulator system is discussed as a potential cause. The results nevertheless
    indicate that the presented method is generally feasible for dimensional CT measurements
    provided that the pose accuracy is sufficient. The calibration procedure can therefore
    be a low-cost and easier to implement alternative compared to trajectory calibration
    methods based on multi-sphere objects, but with a tendency towards lower measurement
    accuracy. The methodology can in principle be transferred to different setups
    with 6-DOF manipulator systems, e.g. C-arm CT devices with a robot arm.

  text: "<jats:p>\r\nDestructive micrograph analysis (MA) is the standard method for
    the assessment of clinched joints. However, during the joint preparation for the
    MA, geometric features of the joint can change due to elastic effects and closing
    cracks. X-ray computed tomography (CT) is a promising alternative to investigate
    the joint non-estructively. However, if the material properties of similar joining
    partners are the same, the CT is not able to correctly resolve surfaces in the
    joint that are close to or pressing onto each other. These surfaces are relevant
    for the determination of characteristic dimensions such as neck thickness and
    undercut. By placing a thin, highly radiopaque tin layer between the joining partners,
    the interfacial area in the reconstructed volume can be highlighted. In this work,
    a method for the localisation of the tin layer inside the joint as well as threshold
    value procedures for the outer joint contour in cross section images are investigated.
    The measured characteristic dimensions are compared with measured values from
    MA of the same samples and of samples without tin layer. In addition, possible
    effects of the tin layer on the joining point characteristics as well as problems
    of the MA are discussed.\r\n</jats:p>"

  text: 'Industrial X-ray computed tomography (XCT) is a tool for non-destructive
    testing and a volumetric analysis method with the ability to measure dimensions
    and geometry inside a component without destroying it. However, XCT is a relatively
    young technology in the field of dimensional metrology and thus faces several
    challenges. The achievement of a high measurement resolution, which is re-quired
    to detect small geometrical features, depends on a variety of influencing factors.
    In this arti-cle, the interface structural resolution (ISR) as one of the key
    challenges will be investigated. The two-sphere standard called the hourglass
    standard allows the determination of the structural resolu-tion by evaluation
    of the surrounding area of an ideal point contact of two spheres after the CT
    re-construction in form of a neck-shaped transition. Close to the contact point
    of the two spheres two opposing surfaces exist. Their distances from each other
    increase as the distance from the contact point of the two spheres increase. The
    determination of the distances between the spheres’ surface allows a statement
    about the ISR. A new developed specimen or standard with a variable gap size consisting
    of calibrated parallel gauge blocks allows statements about the ISR, too. Because
    of the higher number of probing points of the gauge block standard the results
    of the determined ISR are more stable compared to the hourglass standard. This
    paper compares the results of the computed tomography measurements for the designed
    interface structural resolution standard with those of the hourglass standard. '
