Industrial metrological computed tomography system

使用x射线计算机断层扫描（CT）对部件和材料进行无损检测和测量在工业中越来越普遍。这是由于CT方法的众多优点以及它的通用性。与传统的触觉或光学评估方法相比，单次CT扫描不仅可以用于分析外部形状，还可以用于三维分析部件或难以接近的结构的内部。此外，不仅可以进行计量测量，还可以进行材料分析。然而，连续油管技术的性能被其复杂性所抵消，这必须被理解和规范。如果它的潜力得到更好的实现，将出现新的使用领域，在新的工业或其他应用中。近十年来，世界卫生组织一直致力于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重点研究领域——轻量化结构、电动汽车、增材制造、工业4.0和可持续生产——用于测试无损组件分析、组件测量，并作为高精度参考测量技术。到目前为止，这项工作已经使用了Metrotom 800 CT系统，该系统已经使用了9年，专门用于检测直径不超过150mm的轻质塑料部件。采用这种方法，涉及较高密度和尺寸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孔隙的项目，例如金属部件增材制造领域的项目。此外，这对电动汽车领域的共同挑战产生了影响，例如电池和燃料电池的制造，以及电动机的开发。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，再到调查电动机的绕组。此外，这限制了在用户支持领域的研究。例如，所获得的结果只能用于满足严格尺寸和材料限制的组件。可持续生产，特别是再制造，是研究所的一个重要研究领域，在这个领域中，老化的、缺陷方面差异很大的旧产品被自动检测、解构、翻新和再利用。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系统无法满足这种生产的最终需求，特别是考虑到各种变体和所需的存储层集成。基于这些情况，将购买一套新的工业计量CT系统，该系统将符合研究所的精度、分辨率和放射成像性能标准，以及研究所的不同研究问题。

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.
