DIMENSIONAL MEASUREMENTS COMPUTED TOMOGRAPHY IN INDUSTRIAL METROLOGY
What is meant by tomography in the field of metrology?
Computed tomography in industrial metrology is a technology that uses X-rays to scan a component both internally and externally in a non-destructive and comprehensive manner. This allows for highly precise analyses and corrections. Our tomography service enables the identification of errors or defects already in the early development stages of a product, leading to time and cost savings.
Fields of Application
The fields of application are diverse: from the automotive sector to pharmaceuticals and consumer goods; every field involves production processes and is therefore potentially susceptible to errors or defects. Utilizing our tomography service allows for timely intervention, yielding significant advantages.
What are the advantages?
X-ray technology offers immediate benefits in the areas of metrology, inspection, and analysis.
Metrology:
- Comparison: Identifies deviations from the CAD model or the main component and highlights them through a color-defined comparison (in a "heat-map" coloring);
- Dimensions: Checks the exact dimensions of internal and external, including complex, elements;
- Thickness analysis: Displays the wall thicknesses of internal structures in different colors;
- Optimization of tools and processes: Provides information on the condition of tools and the production process; Development and reverse engineering: Creates a point cloud in .STL format, which is then used for CAD modeling, generating 3D surfaces in .STEP or .IGES format (reconstruction of the mathematical model of surfaces and internal volumes);
- Metrological analysis of assembled parts composed of different pieces and materials (material mix), allowing for the measurement or re-engineering of the individual component.
- Defect analysis: Quickly and easily detects any defects;
- Assembly control: Checks the function and fit accuracy of assembled parts;
- Control of joining technologies: Verifies that welded, brazed, glued, or riveted joints are truly perfect;
- Detailed analysis of the fit accuracy of the individual component in assembled parts.
- Structural analysis: Provides important details about the structure of the products;
- Analysis of fiber composite structures: Shows the 3D distribution and orientation of various elements within a composite material;
- Defect analysis: Highlights surface or internal defects of parts in different materials, such as blowholes, cold shuts, qualitative and quantitative analysis of internal porosity and its distribution within the part.
How is the tomography service conducted?
In our dimensional laboratory, this service is carried out using our ZEISS METROTOM systems. ZEISS METROTOM is a line of industrial computed tomography machines for measuring and inspecting complete plastic or lightweight metal parts. Thanks to a large front door, the ZEISS METROTOM allows the operator direct access to the system to perform measurements easily and safely, while also providing the possibility of entering the machine for maintenance work.
