Computed tomography

Computed tomography

Computed tomography has been one of our core competencies ever since the firm was established. This measurement technology – called CT for short – is one of the newest processes in industrial measurement technology. It is based on X-ray technology and offers many advantages.

3D data with our computed tomography machine

Computed tomography can be used to measure even complex components accurately and non-destructively. You can even look inside the components, thanks to the modern computed tomography in our ZEISS METROTOM devices. To do this, we place the respective component into the measuring cabin and start the scan. Within a very short space of time, the computed tomography machine provides us with conclusive 3D data for further quality analysis.

Complet and non-destructive component analysis

What is particularly impressive about computed tomography is how it works, which enables components to be analysed completely and non-destructively. Clamping force or contact force – which usually occur with other measurement processes – do not impact the components in CT. The geometric data captured is fixed, and can be processed graphically and permanently stored. The data evaluation often delivers findings which can be used to speed up initial sampling phases and editing loops, for example. 

So, computed tomography means that we can meet the expectations associated with component analysis ideally. That way, the highest standards of quality are ensured, while processes of industrial development and approval are sped up at the same time.

Non-destructive 3D component measurement

One of the most significant advantages of computed tomography is that it enables the 3D measurement of a component without destroying it. So, components can be measured fully without restrictions or destruction. This innovative technology works contact-free so that there is no clamping and/or contact force impacting the component. All geometries in the component can be measured without complex slices. This also applies to undercuts, tight contours in lower areas, and much more.

The 3D point cloud created by computed tomography is fixed. That means that this digital data can be reconstructed at any time. So we can also perform more evaluations later, carry out a more in-depth analysis and examine new issues with regard to the component.

3D nominal-actual comparison + 3D actual-actual comparison

The 3D nominal-actual comparison shows deviations between a component and the CAD model. To do that, we use a graphic false-colour representation. Within a very short space of time, we can therefore draw conclusions as to the conformity of the components.

In the 3D actual/actual comparison, components from different batches can be compared directly.

Tool offset data

During the computed tomography scan, we capture the component surface extensively and can therefore easily illustrate and determine any deviations from the target geometry in 2D or 3D. That way, we can provide you with accurate offset data for the tool revisions. The accurate data also means that tool offset data can be performed faster and in a more targeted way. 

Blowhole and porosity analysis

If there are extraneous materials, blowholes or inclusions in your components, these can be discovered with the help of computed tomography without the component being damaged or even destroyed. We can process the results in different variations. The customary variations are cross-sectional observations, transparent 3D representations or a typical report, in which we give an accurate list of the number, size and position of the blowholes, inclusions or extraneous materials.

Assembly inspection

Computed tomography can be used to reliably check the correct assembly of even complex components consisting of many individual parts. That means that the exact attachment of nuts, seals and ball-ends etc. can even be checked when they are concealed under another component.  Quality control therefore raises the bar completely. 

Defect and damage analysis

As computed tomography not only views the component from the outside but also allows you to look inside, a damage or defect analysis can be performed even if the component has already been assembled. That means it is possible to detect early on whether repair is possible or would make sense, or whether it would be better to replace the part completely. In the case of groups of components that have been the subject of complaints, CT scans deliver valuable information for finding the cause of the damage. For instance, we can quickly find a crack inside the component even if it can’t be seen from the outside.
