Traceability investigation in Computed Tomography using industry-inspired workpieces

This paper concerns an investigation of the accuracy of Computed Tomography (CT) measurements using four industryinspired workpieces. A total of 16 measurands were selected and calibrated using CMMs. CT measurements on industryinspired workpieces were carried out using two CTs having different metrological performance. Different scanning strategies and parameters were selected between two CTs in order to better understand the impact of the operator. The quantification of the measurement uncertainty for CT measurements was also achieved using two different approaches. Metrological compatibility between CTs and between CTs and CMMs was finally assessed using the En value concept.
