Check out this case study. This is just one example of what computed tomography can do for you.
In this case study the analysis of a typical aluminum die-cast part with a size of 110 mm x 70 mm x 65 mm is demonstrated.
These parts undergo a material analysis, a dimensional check and a complete nominal-to-actual comparison.
At the end of the scanning procedure the reconstructed data is available as voxel (three-dimensional pixel) data as well as surface data.
This data is the basis for all following analyses. At this point you could create a .stl file as well as have the ability to start the Reverse Engineering process.
A comparison of the scanned data and the CAD model is carried out to completely analyze form deviation and deformation of the part.
The deviations of the real part to the CAD data are visualized with a color plot. Detailed information about the size of deviations can be displayed with labels. This image shows the deviations of the die-cast aluminum part with colors.
In another work step, porosities are detected and analyzed on the basis of the scanned data. With color coding the pores are categorized by their size.
Therefore the distribution of the pores can easily be recognized. This step gives you the capability of non-destructive testing. You can see porosity without destroying the part.
When using a conventional testing method the part has to be destroyed. Industrial Computed Tomography allows the non-destructive three-dimensional testing of the part.
An important feature is the ability of the CT system to detect very small pores even in large aluminum castings.
The dimensional evaluation of the part is carried out with the measuring software Metrosoft QUARTIS. Element capturing, geometrical evaluation and reporting are done within the measuring software. The surface data, captured with the industrial CT, is used for the probing of the measurement points.
A once prior written measuring program can be selected and fully executed automatically. With this method even internal and the smallest structures, which cannot be measured by tactile or optical methods, can be dimensionally measured and evaluated.
