Reference standards for XCT measurements of additively manufactured parts – A Obation et al.
X Ray CT/11 Abstract An increasing number of industrial sectors are considering the potential of additive manufacturing as an asset to improve theirproduction. Indeed, additive manufacturing enables the fabrication of very complex geometries and inner cavities that cannot bemanufactured with conventional techniques. However, in critical sectors such as aerospace, defence and medical, the parts needto…

On the importance of multi-material acceptance testing for CT-based CMSs – F. B. Oliveira et al.
X Ray CT/10 Abstract As the use of multi-material objects in industry continues to rise, the need for geometrical quality control by means of computed tomography-based coordinate measurement systems (CT-based CMSs) for entire geometries is rising as well. But the lack of international standards and the limited knowledge available on the influence of multi-materials on dimensional CT…

Modular test parts to assess the quality of computed tomography dimensional measurements – V. C. Nordelli et al.
X Ray CT/9 Abstract This paper presents a set of modular test parts specially designed for the evaluation of the extraction operation using CT measuring systems. The motivation in developing the test parts was to individually quantify different types of CT-induced measurement errors and their influence on measurement results. The characteristics of the test parts…

Performance testing of dimensional X-ray computed tomography systems – Zwanenburg et al.
X Ray CT/8 Abstract X-ray Computed Tomography (XCT) has become a common tool for dimensional analysis as it allows for non-destructive internal and external measurements. Manufacturers often specify the accuracy of dedicated metrology XCT systems as a maximum permissible error (MPE) statement determined using workpieces, test lengths and positions that are significantly different between manufacturers….

Uncertainty in measurement for x-ray-computed tomography using calibrated work pieces – R. Smith and C. Niggermann
X Ray CT/6 Abstract This paper presents the principles of industrial x-ray-computed tomography (XCT) and its enormous potentials for the non-destructive 3D measurement and quality assurance of technical parts. Due to many overall factors and many nonlinear factors having an influence on the tomographic imaging process, the reconstructed volume model and thus the measurement results,…
