CT SCANNING
Industrial Computed Tomography
Applications in Dimensional Inspection

Non-Destructive Problem Solving
THE BASICS: What does an Industrial CT look like?
THE PROCESS:
-
Part is placed on the rotary table
​
-
The table is rotated 360º (this step takes 5-60 minutes)
​
-
During rotation, 100’s of images are captured
​
-
Images reconstructed into 3D dataset
​
-
Dataset captures all internal and external characteristics.
Heading 1
Example Part & Resulting Data: Y-Connector
Y-Connector
VOXEL DATA
Non destructive 2-D Cross Sectioning
-
An infinite number of 2-D cross sections can be cut from the 3-D part data
​
-
Different materials show up as different colors (note how cap compresses rubber washer)
​
-
Data can be used to confirm assembly fits
​
-
Data can also be used to check internal characteristics
Non Destructive 3-D Cross Sectional Measurement
-
3-D part data can be x- sectioned from any orientation
​
-
Data can be used to confirm assembly fits.
​
-
Data can also be used to verify if characteristics meet their blueprint specification
​
-
Green boxes represent features within tolerance. Red boxes represent out of tolerance features.
GD&T Measurement Analysis
-
Using Zeiss Calypso software, we can confirm and report any blueprint dimension.
​
-
Calypso has a robust GD&T math engine that can evaluate any Y14.5 drawing callout.
​
-
Data can be reported in endless formats, shown here in an excel spreadsheet.
CT: Resolution (why is magnification important)
You cannot measure what you cannot see (resolve)
No Magnification (full part scanned)
​With Magnification (1/3 of part scanned)
Industrial CT Scanning
-
We’re fast. You receive your first article inspection report in days.
​
-
We help you save money. The ability to inspect without disassembling, and by expediting the design and development process, allows you save on operating costs.
-
Our process is non-destructive, giving you the ability to inspect internal and external geometry.
​
-
We don’t require fixturing or clamping forces, which can distort the part.
-
Our process helps you increase production ability with faster prototypes and replications without relying on CAD files.
-
Our X-ray based measurement system is non-contact (no force).
-
Parts do not require potting.
-
We’re accurate. In fact, plastic color and depth-of-feature will not affect accuracy or repeatability, which can be a problem with Part-CAD comparisons.
-
Our process lets you quickly determine whether a part has any critical defects.
-
We provide an option for extensive porosity (voids) and wall thickness reports.
