CT Scanning Applications


There are a number of CT Scanning applications, ideal for obtaining internal and external information about an object

CT Scanning Applications include;
Comparison – Part to CAD

Scanned parts can be compared to the original CAD model for the component. The two sets of data can be aligned by either ‘best fit’ or by predetermined datums. The results can then be modelled in comparison to the CAD data, pictorially showing areas and degrees of deviation of both internal and external geometry.

Comparison – Part to Part

Data from two or more scanned parts can be compared. As above, the data sets can be aligned by either ‘best fit’ or by predetermined datums. The results can then be modelled, pictorially showing areas and degrees of deviation of both internal and external geometry between the parts.

Composite Analysis

When analysing composite components CT scanning can identify the varying density of materials within the part. From this the composite fibres can be examined for; length, diameter, and their predominant direction. Results can identify if the density and location of the fibre meet the intended design requirements.

Quality Inspection

CT Scanning is used in quality inspection as a fast and effective way to identify potential issues within parts and assemblies. Whether a component is slightly deformed or completely broken, failures can be identified by visual inspection of CT scan data or by comparing the scan data to the original CAD data.

First Article Inspection

First Article Inspection (FAI), is a formal design validation and documentation method for components created from such manufacturing processes as injection moulding, casting or machining. CT Scanning allows components to be quickly and accurately scanned (including internal geometry where required), both individually and as part of an automated process which allows multiple parts to be simultaneously analysed.

Reverse Engineering

Reverse engineering includes taking data from a physical object or component which is then used digitally to create CAD drawings. There are several advantages to using CT scanning to undertake this data capture. The first, as mentioned above, is that CT scans allow the data for internal components to be obtained where other line-of-sight data capture methods (ie; laser scanning) are unable to acquire this data in a non-destructive way. Another is the speed by which CT scanning captures hundreds of thousands of data points. This data generates a 3D point cloud which is ultimately converted into a CAD file format.
