Studies on measurement uncertainty and economy of dimensional computed tomography measurements on selected examples

Industrial computed tomography (CT) is increasingly being applied for non-destructive testing of components in process quality assurance. The advantage over tactile or optical measuring methods is in particular the possibility to measure both, outer as well as inner geometry features non-destructively. In this article, possibilities for increasing the economy of CT measurements by simultaneous tomographic scanning of several components in the CT measuring volume are being investigated by using selected components, and the measurement uncertainty for the individual scanning settings is determined experimentally.
