Non-destructive testing and measuring of components and materials using X-ray computed tomography (CT) is increasingly prevalent in industry. This is due to the CT method's numerous advantages as well as its versatility. In comparison to traditional tactile or optical assessment methods, a single CT scan can be utilized to analyze not just the outside shape, but also the interior of a component or difficult-to-access structures in three dimensions. Furthermore, not only metrological measurements but also material analyses are possible. However, CT technology's performance is offset by its complexity, which must be understood and regulated. If its potential is better realized, new areas of use in new industries or for other applications will emerge. For almost ten years, the wbk has been involved in CT research and implementation. In addition to the development of user support systems, the technology is used in the institute's key research areas - lightweight construction, electromobility, additive manufacturing, Industry 4.0, and sustainable production - for testing non-destructive component analysis, component measurement, and as a high-precision reference measurement technique. To date, the work has been done using a Metrotom 800 CT system, which is now 9 years old and is specifically intended for the inspection of lightweight plastic components with diameters up to 150 mm. With this approach, research activities involving components and materials of higher density and size are either impossible or only possible to a limited extent. The deficiencies impede projects requiring the detection of pores, such as those in the field of additive manufacturing of metallic components. Furthermore, this has an impact on common challenges in the field of electromobility, such as battery and fuel cell manufacture, as well as the development of electric motors. Activities in these areas range from defect detection to determining anode overhang in battery cells to investigating windings in electric motors. Further, this limits research in the field of user support. For example, the results achieved can only be used for components that meet the strict size and material restrictions. Sustainable production, particularly remanufacturing, is an important research field for the institute, in which deteriorating old products with significant variance in terms of flaws are automatically inspected, deconstructed, refurbished, and reused. The required circular factory will be developed and built as part of a collaborative research center. However, the current CT system cannot match the resulting needs for such a production, especially given the variety of variants and the required store floor integration. Based on these circumstances, a new industrial metrological CT system will be purchased that will match the institute's standards for accuracy, resolving power, and radiographic performance, as well as the institute's different research questions.

利用X射线计算机层析成像(CT)对部件和材料进行无损检测和测量在工业中日益普遍。这是由于CT方法的许多优点以及它的多功能性。与传统的触觉或光学评估方法相比，一次CT扫描不仅可以用来分析外部形状，还可以用来分析部件或难以接近的结构的三维内部。此外，不仅可以进行计量测量，还可以进行材料分析。然而，CT技术的性能被其复杂性所抵消，这必须被理解和监管。如果更好地实现其潜力，新的行业或其他应用将出现新的使用领域。近十年来，WBK一直致力于CT的研究和实施。除了开发用户支持系统外，该技术还用于该研究所的关键研究领域-轻质建筑、电动汽车、添加剂制造、工业4.0和可持续生产-用于测试无损部件分析、部件测量，以及作为高精度参考测量技术。到目前为止，这项工作是使用Metrotom 800 CT系统完成的，该系统现在已有9年的历史，专门用于检查直径不超过150 mm的轻型塑料部件。使用这种方法，涉及密度和尺寸更高的部件和材料的研究活动要么是不可能的，要么只能在有限的范围内进行。这些缺陷阻碍了需要检测气孔的项目，例如金属部件添加剂制造领域的项目。此外，这对电动机动性领域的共同挑战产生了影响，例如电池和燃料电池制造，以及电动马达的发展。这些领域的活动范围从缺陷检测到确定电池单元的阳极悬垂，再到调查电动马达的绕组。此外，这限制了用户支持领域的研究。例如，所取得的结果只能用于满足严格尺寸和材料限制的零部件。可持续生产，特别是再制造，是该研究所的一个重要研究领域，在该领域，对缺陷差异很大的劣化旧产品进行自动检查、解构、翻新和重复使用。所需的循环工厂将作为合作研究中心的一部分进行开发和建设。然而，目前的CT系统不能满足这种生产的需要，特别是考虑到各种变种和所需的商店地板集成。基于这些情况，将购买一种新的工业计量CT系统，该系统将符合研究所在精度、分辨率和射线性能方面的标准，以及研究所的不同研究问题。
