Component Verification Using X-ray Computed Tomography and CAD Comparison
The following video and training material will use 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 in ensuring
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 will
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 to users who want to assess machined
or additively manufactured components.
