Industrial X-ray computed tomography (XCT) is a tool for non-destructive
testing and a volumetric analysis method with the ability to measure
dimensions and geometry inside a component without destroying it.
However, XCT is a relatively young technology in the field of
dimensional metrology and thus faces several challenges. The achievement
of a high measurement resolution, which is re-quired to detect small
geometrical features, depends on a variety of influencing factors. In
this arti-cle, the interface structural resolution (ISR) as one of the
key challenges will be investigated. The two-sphere standard called the
hourglass standard allows the determination of the structural
resolu-tion by evaluation of the surrounding area of an ideal point
contact of two spheres after the CT re-construction in form of a
neck-shaped transition. Close to the contact point of the two spheres
two opposing surfaces exist. Their distances from each other increase as
the distance from the contact point of the two spheres increase. The
determination of the distances between the spheres’ surface allows a
statement about the ISR. A new developed specimen or standard with a
variable gap size consisting of calibrated parallel gauge blocks allows
statements about the ISR, too. Because of the higher number of probing
points of the gauge block standard the results of the determined ISR are
more stable compared to the hourglass standard. This paper compares the
results of the computed tomography measurements for the designed
interface structural resolution standard with those of the hourglass
standard.
