Computed tomography (CT)

X-RAY- The look inside

Industrial Computed Tomography (CT) is an important tool for a high-quality product and process development, ensuring safe process monitoring and requalification. Digital images of a CT, which is a 3D volume model can be created from an entire component. Complex component and multi-material combinations can easily be detected with a CT. Even with additively manufactured components (3D Printing), a CT is used as the most expedient measuring technology method. The advantage is that we can measure internal or hard-to-reach areas where tactile measuring methods reach their limits.

The 3D solid model contains comprehensive data from both the external and internal nature of the component. Therefore, defects such as cracks, inclusions, impurities or gas inclusions can be reliably detected. Products from the casting industry (plastics or metals), a CT is often used in the contest of porosity analysis (blowhole analysis). Based on the complete detection of all existing voids in a component, castings can be analyzed and qualified according to a required factory or customer standard (example P201/ P202) or a specific target criterion.

Furthermore, the high-precision 3D reconstruction allows target-performance comparisons (component vs CAD model), wall thickness analysis or fiber composite analysis.

The cross-sectional representation of individual component layers replaces the traditional, destructive and time-consuming mechanical creation of micrographs. CT digitized components can be virtually traversed in any spatial direction and thus offer almost any number of cross- sectional images in different spatial directions.

Using the 3D model, polygon meshes (*.stl) can be calculated, which can be further processed using standard CAD or measurement programs (surface return). The digitized surfaces can be precisely measured with appropriate software, which also contributes to non-destructive computed tomography (CT) to the rapidly growing field of optical metrology.

The 3D volume file is provided by us with the desired analysis, tables and results as well as a free viewing software for data viewing.

Project flow in three phases

Phase 1: Detection of the actual state

After the precise recording and assessment of the actual state, we define the required examination method and the test process.

Multi-shift operation ensures efficient and flexible execution of the entire project sequence, which enables a 100% check depending on the type of component or cycle time.

Phase 2: Scan & Evaluation

• Perform the CT scan
• Data reconstruction
• Analyse
• Faulty Analysis
o  Porosity Analysis
o  Inclusion Analysis
o  Crack Analysis
• Wall Thickness Analysis
• Fiber Composite Analysis
• Solder Joint Analysis
• Target-performance Comparison
• Measurement
• Assembly Control
• Flächenrückführung
• Reverse Engineering

Phase 3: Documentation

With the results, we work with you so that you can draw the right conclusions for your quality assurance. We offer different types of application reports (user friendly). We also follow your company standards, so that the results can ideally be transferred directly into your own documentation.

nominal-actual comparison

Target-performance comparisons (component vs CAD model)

The target-actual comparison offers the direct comparison to a CAD model or a second volume model an other part. Thus, without creating a measurement program can already be determined whether the target specifications have been maintained.
