Abstract
Industrial CT equipment are increasingly used to determine the dimensions of geometric features (e.g. diameter, position, cylinder) in the industry. In the course of using this new measurement technology in the field of quality control it has to be verified the measured data. In this article the measurement error and uncertainty of the micro computed tomography are investigated by the performing designed experiments. The setting parameters of the CT are changed systematically (RSM method, CCD design) to determine the distance of two ruby spheres. These spheres are the parts of a calibrated ball bar which is connected to an Al test piece during the experiments. The purpose of this work is to make emphasis of the adjustment of the voxel data in case of dimensional measurements performed by industrial computed tomography.
