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.
