Computed Tomography (CT)

The procedure

Industrial computed tomography differs from conventional medical computed tomography due to the test objects (density, composition, size, etc.), test tasks (detail scans, fast scans, etc.) and the evaluation possibilities. The most frequently used computer tomographs are the following:

2D computed tomography

The two-dimensional CT examines individual layers of the object and reconstructs them. This means that the system uses a line detector (surface beam/LDA) to create a two-dimensional image of the rotating body.
A 3D view is created by means of several scans or "sections" (numerical image sequence) of the test object, which are assembled into a 3D body by a program such as the VG Studio Max used by my employer.
An automated evaluation by the machine is only partly meaningful due to the increased scanning effort to generate a 3D volume.

3D computer tomography

In contrast to the two-dimensional CT, the three-dimensional CT examines the entire volume of the test object.
For this purpose, the X-ray source emits a cone beam onto the rotating body and a surface detector detects the residual radiation necessary for the creation of the volume body.
Due to the complete volume detection, the 3D-CT is able to perform a fast automated evaluation.

Possible Applications

Defect Analysis

With the help of porosity/inclusion analysis, your components can be examined for internal defects such as pores, blowholes and inclusions. The visualization is carried out according to your wishes and offers the following advantages:

  • Automatic detection of all pores, cavities and inclusions
  • Rejection of actual defects as 3D volume for casting simulation (e.g. MAGMA, CATIA, etc.)
  • Attractive data visualization options (e.g. color defect display) in the form of images and videos
  • Comprehensive and customized reporting

 


P202/P201 Analysis

(extended porosity/inclusion analysis):

With the P202/P201 analysis (extended porosity/inclusion analysis) your components can be examined for pores in a certain 2D sectional view according to VDG P202/VW 50093 and P201/VW 50097. The advantages are:

  • Non-destructive and detailed analysis results with information about the individual pores and reference surfaces as well as comprehensive statistical information similar to a microsection in the laboratory.
  • Appealing data visualization options in the form of images
  • Comprehensive and customized reporting

Target/actual comparison / before-and-after comparison:

By means of the target/actual comparison, your components can be compared to your CAD data with regard to their dimensional accuracy. It is also possible to compare several components with each other or to examine a component for changes before and after its use (endurance run). The most important advantages are:

  • Information content compared to 3D scanners (detection of internal walls / additional detection of defects)
  • Appealing visualization options for the data (e.g. color display of deviations/changes) in the form of images and videos
  • Comprehensive and customized reporting capabilities

reverse engineering

Missing CAD data - Missing spare parts - No problem, using reverse engineering of the CT to the appropriate STL (polygon mesh or point cloud) or CAD data set. We would also be pleased to make you an offer for the pressure or casting of the component. Further advantages are:

  • Fast, precise and cost-efficient data generation for existing components
  • Everything from a single source - from data generation to the finished component

Dimensional accuracy test:

By means of the dimensional accuracy test, external and internal component dimensions can be checked for their compliance. This can be done on the basis of technical drawings or your own specifications. Below are the most important advantages at a glance:

  • Information content compared to 3D scanners (recording of internal dimensions / additional recording of defects)
  • Attractive data visualization options (e.g. 3D visualization with desired dimensions) in the form of images and videos
  • Comprehensive and individual reporting options

Special tests using CT (e.g. archaeology)

Non-destructive examination of historically important and/or valuable objects for their conditions and/or authenticity. The most important in brief:

  • Obtaining information on the authenticity of an object by comparing the CT images with relics/objects of the time
  • Attractive visualization possibilities of the relics for posterity
  • Comprehensive and customized reporting capabilities

advantages

  • Evaluation of your components in up to a few seconds
  • Testing of your components in small to large series
  • 100% production control without any risk
  • Complete 3D representation instead of 2D partial view
  • User independent test results through innovative evaluation software
  • Fully/semi-automatic process
  • Shop floor system for your product line
  • Completely non-destructive evaluation of your components
