Description
Summary:In recent years, computed tomography (CT) has been applied as an industrial metrology tool for the dimensional evaluation of visible and even hidden features of production parts in a non-destructive manner. Considering the experimental findings of a recent work of the authors, this paper deals with the effect of voxel size on measuring distances between feature-of-size centers, which would be less sensitive to edge offset errors. Particular attention is given to the design of experiment and to the measurement uncertainty sources. The most significant experimental findings are outlined and discussed in this paper.
