The advantages offered by X-ray computed tomography (XCT), e.g. the capability to inspect and measure complex geometries and non-accessible or internal features in a non-destructive way, are at the basis of its rapid diffusion in the field of manufacturing metrology.

Abstract
The advantages offered by X-ray computed tomography (XCT), e.g. the capability to inspect and measure complex geometries and non-accessible or internal features in a non-destructive way, are at the basis of its rapid diffusion in the field of manufacturing metrology. However, a large number of influence factors affect the metrological performances of XCT systems. One of the main variables is the material of the inspected object. In this work, the influence of the material of the artefact used for testing the XCT system is addressed. A reference object was developed, consisting on a hole plate which can be made out of different materials and used to evaluate the performances of a metrological XCT system. The position and the diameter of the holes were specifically designed to match with a ball plate that can be used together with the hole plate in a combined way. Experiments were carried out using the objects separately and combined.Pubblicazioni consigliate
