Computed tomography & gear measurement technology

This article examines the use of computed tomography (CT) in gear metrology, with a particular focus on the direct comparison of gear parameters with tactile gear measuring devices. The aim is to demonstrate the impressive possibilities of CT technology in the field of gear metrology and to show the great advantages of exaCT computed tomography in gear metrology.

Industrial computed tomography has been firmly established in dimensional metrology for several years now. It is often the only way to check the geometric tolerance of components, particularly when determining complex geometries that are not accessible by other optical or tactile methods. A major advantage of the technology is that, in addition to the geometric inspection, the material of the component can also be checked for defects in order to avoid component failures.
