Digitization of components: Quality through method diversity
Tactile scans and tomography
The right combination for optimal data
The quality and usability of digitalized component data depend largely on the selected acquisition methods. We rely on a combination of measurement methods that produce STL data (“Standard Triangle Language”) and CT volume data (“computer tomography”). We use these methods and procedures:
Optimization of component detection
These are the advantages of the process
In order to achieve the best possible capture accuracy, the choice of the optimal method is crucial. Each method has specific advantages for the digitization of components: the choice of method depends on the specific requirements of the project. For example, tactile methods are often the better choice for surface measurements, while a non-destructive view of the inside of a component can only be achieved using computer tomography.
By using combined scanning methods, we can make optimum use of the strengths of individual technologies, combine data and thus create a detailed and accurate digital model of your component. Here are the strengths of the individual methods:
For precise measurements with very low deviation at specific measuring points, 3D scanning is the method of choice: it is ideal for recording fits or gear measurements, but also provides information about surface properties - and for virtually all materials.
In addition to the high measurement precision, the repeatability of measurements is one of the major advantages of tactile methods. They are also data-efficient, limiting the measurement to precisely defined points and therefore generating less data than, for example, comprehensive computer tomography.
CT scans capture the complete internal and external geometry of a component in 3D. This enables a detailed examination of complex structures and geometries that are difficult to access using conventional methods.
A major advantage of computed tomography is the ability to analyze hidden internal structures, such as cavities, inclusions or weld seams, without having to open the component. Air inclusions, as well as warpage and shrinkage, can therefore be tested non-destructively.
Industrial CT generates detailed grey-scale voxel volumes that can be displayed in sectional views using specialized viewer programs. This technology makes it possible to identify and statistically evaluate internal defects such as blowholes, vacuoles, inclusions or cracks. Standardized component geometries and analysis parameters are crucial for the consistency of the results.
Defined sectional planes within the CT volume allow porosity parameters such as pore content, pore diameter, pore spacing, number of pores and pore nests to be precisely determined. Compliance with standard specifications (e.g. VW50093 or P202) ensures the reproducibility of the analysis results.
CT analysis offers the unique opportunity to check the correct positioning of inlets in assembled components or to find the causes of defects in non-functional devices without having to dismantle or damage them. Advanced viewer functions also enable the generation of 3D views and the use of various clipping techniques.
The analysis of surfaces and the calculation of fiber orientations in materials such as CFRP or GFRP are based on the grey value volume data from CT. These methods allow the fiber orientation and the fiber volume fraction to be displayed in color-coded form, as vectors or using tensors.
The right data format
Creation of STL and CT volume data
STL files are particularly indispensable in rapid prototyping, 3D printing and reverse engineering. They provide a three-dimensional representation of the component surface using interconnected triangles. The volume data generated during computer tomography also provides insights into the internal structure of the components and enables comprehensive analysis.
The digital capture of components is the first step on the way to precise measurements, analyses or reverse engineering. By combining different scanning methods, we ensure that you receive reliable data that enables trouble-free further processing.
