Component Verification Using X-ray Computed Tomography and CAD Comparison
The following video and training material uses an additively manufactured con rod to demonstrate how the surface profile generated from X-ray CT data can be compared to the original component CAD design.
In the manufacturing
industry, dimensional precision of components is a critical aspect of ensuring that components will fulfill their desired role. Exposed surfaces can be validated
using CMM techniques, while X-ray Computed Tomography (CT) can be used for
verification of external and internal features. The following resources explain how the Avizo Software visualization package can be used to compare the
surface profile of a manufactured component analyzed using X-ray CT to the
original CAD design to reveal deviations in the surface dimensions. This
analysis methodology is particularly useful for users who want to assess machined
or additively manufactured components.

To follow this training, you should have a general knowledge of Avizo Software, including not only the basics such as data loading, interacting with the 3D viewer, connecting modules, but also using colormaps, accessing the Tcl Console, and switching on Units management.
We encourage you to download the training material, which contains a lot of additional information, as well as the dataset used in this tutorial from the Download link (located in the right column).
