Comparative Analysis of Surface Determination Techniques in Coordinate Metrology with X-Ray Computed Tomography
Year: 2025
Type: article
Abstract: X-ray computed tomography (XCT) is an inspection technique that has gained significant importance in coordinate metrology, thanks to its ability to capture detailed information about complex-shaped parts. The XCT process involves multiple steps, each contributing to uncertainties. One crucial aspect in dimensional and geometrical metrology is the surface determination technique (SDT), which focuses on distinguishing the boundaries of the scanned object. Despite its importance, there is still a lack of research on how various SDTs affect the outcomes of coordinate measurements. This research aims to provide an in-depth comparison across a variety of dimensional and geometrical measurands to assess the performance of multiple SDTs. Measurements from coordinate measuring machines serve as the references for comparison.
