Abstract

Computed tomography as a non-contact and non- destructive method is of great interest for use in dimensional measurements. It is a method that enables insight into internal structure of inspected part and measurement of internal geometry, but one big disadvantage of the method is lack of metrological traceability. In order to assess measurement uncertainty and achieve metrological traceability, parameters that influence CT dimensional measurements must be defined and their contribution to overall measurement uncertainty must be assessed. One of the parameters that influence CT measurement is influence of object geometry and characteristic of object surface. In this paper, influence of surface roughness, as the parameter of inspected object, on CT dimensional measurements will be investigated and results will be analyzed.
