NOMINAL TO ACTUAL COMPARISON
Comparison between CAD nominal and CT scanned data
A typical task carried out by X-Ray Computed Tomography scans is the nominal-actual comparison, visualizing geometric deviations between the data of a scanned workpiece and a CAD nominal model. A valuable comparison can be performed between the actual geometry, the CT volume, and a golden reference, the reference workpiece.
Deviations are displayed using a colour code providing a visual representation of the differences between parts. The nominal/actual comparison is an efficient and easy-to-use tool to qualify components and improve production processes, applicable in the multiple industries and applications, as injection moulding and 3D printing.
