Computed Tomography (CT) scanning has the ability to see the inside features and components and this is a huge advantage as they can be seen in their functioning position and can be analysed without disassembly.

Computed Tomography (CT) Scanning

Industrial CT scanning is a process which uses X-ray equipment to produce three-dimensional representations of components both externally and internally. Industrial CT scanning can be used in many engineering sectors for internal inspection of components. The key uses for CT scanning are flaw detection, failure analysis, metrology, assembly analysis and reverse engineering applications.

There are many advantages to using CT scanning over traditional techniques such as Coordinate Measuring Machines (CMM) or 3D laser scanners. Some of the main points include:

  • Non-destructive test for inspection and metrology.
  • Reduced costs in creating the first CAD model due to data capture.
  • Design requirements for both internal and external components are validated quickly and accurately.
  • Product quality is improved to reduce the risk of recalls.
  • Internal complex features can be precisely measured without destructive testing.
  • Parts are scanned in a ‘free-state’ environment without fixtures applying stresses that could damage delicate parts or display warping not present in the part.
  • Rapid prototyping of the internal components can be completed without the task of creating the CAD file from scratch.

One of the most recognised forms of analysis using CT scanning is assembly or visual analysis. CT scanning has been largely used for medical purposes. For industrial CT scanning, the ability to see the inside features and components is a huge advantage as they can be seen in their functioning position and can be analysed without disassembly. Our CAD software can take measurements from the CT data. These measurements are useful for determining the clearances between assembled parts or simply a dimension of an individual feature.

In today’s market parts can be manufactured around the world: designed in one country, machined in another and assembled in a third.

Verification of the part to the original design is critical, especially if the part is to be used in an assembly. Any variances, for both external and internal geometries can be shown on the surface colour maps and therefore identify any errors that may have crept into the manufacture process from the original CD model. This process is beneficial when comparing the same part from various suppliers, studying the differences in parts from one cavity to another cavity from the same mould, or verifying the design to the part.

Void analysis

Traditionally, determining an object’s porosity would require destructive testing. Computed Tomography (CT) scanning can detect internal features and flaws without destroying the part. Industrial CT scanning is used to detect flaws inside a part such as porosity, an inclusion, or a crack before a failure can occur.

Metal casting and moulded plastic components are typically prone to porosity because of cooling processes, transitions between thick and thin walls, and material properties. Void analysis can be used to locate, measure, and analyse voids.

Generation of CAD data for reverse engineering requirements

A CAD file can be generated from the CT data, which is particularly useful in reverse engineering applications and product development. Exported CAD file formats are recognized by many analysis software such as computational fluid dynamics (CFD), finite element analysis (FEA), Fluid Dynamics and Mold Flow software. The CAD file created by CT scanning can show external and internal components. This allows for first-time rapid prototyping of internal components without the daunting task of creating an entirely new CAD file.
