digitization, reverse engineering and quality control
High-precision 3D scans
Thanks to our advanced 3D scanning, we can detect and digitize objects of any shape or size with the highest accuracy. Our technologies enable us to obtain a detailed polygonal model with accuracy down to 0.03 mm with stationary machines e 0.05 mm with blue light anthropomorphic systems., covering surfaces from a few square centimeters up to objects in scale automotive and aeronautical (up to 60 meters).
What are 3D scans used for?
The main applications of 3D scans include:
3D RECONSTRUCTION
of a physical object
DIMENSIONAL VERIFICATION against the project CAD file
EVOLUTIONARY MODELING, to transform a physical object into a new engineered project.
THE PROTOTYPES METHOD:
manual CAD remodeling
Reverse engineering consists of reconstructing an analytical CAD file from a polygonal model. There are different approaches: some services are limited to automatic conversion (auto-patch), generating an .IGS or .STP file with “mesh” geometries, which are very heavy and non-modifiable, replicating even the defects of the original object.
Our approach is completely different.
Through the experience of our operators, we model the file with parametric 3D tools, creating lightweight, rigorous and fully modifiable solid models. This approach allows us to:
The comparison between the detected data and the functional analysis by an expert technician also allows us to identify critical thicknesses, stressed areas, weak points or design errors, maximizing the functionality of the new prototype.
Dimensional control (CTR)
The comparison between the real data of a piece, acquired through a 3D scan, and the related theoretical 3D file produces a color map that highlights the differences point by point between the two models.
The color map will then be calibrated to identify the areas that are within the required tolerance spectrum (which will be colored in green) and the areas that are outside the required tolerance spectrum (these areas will be colored in shades of blue if they are smaller than the theoretical data or colored in shades of red if they are larger than the theoretical data).
Therefore, the green-red-blue color map allows for a quick evaluation of product conformity (simply put, the best product is the one entirely colored green because it is totally within the expected tolerances)
Furthermore, dimensional control also allows the analysis of typical production defects (deformations, distortions, warping, residual stresses) or the identification of specific errors related to damage, incorrect processing, tool wear, dents, breakages, and much more, providing information about the areas involved and the extent of deviations down to hundredths of a millimeter.
Accessibility to 3D scanning
The comparison between the detected data and the functional analysis by an expert technician also allows us to identify critical thicknesses, stressed areas, weak points or design errors, maximizing the functionality of the new prototype.
Thanks to the integration between 3D scanning, advanced CAD modeling and rapid prototyping, we can reconstruct complex mechanical parts from historic or high-value vehicles.
We perform 3D reconstruction of components such as:
- engine bases,
- cylinder heads,
- gearboxes,
- transmission groups,
- turbines and turbochargers,
obtaining perfectly functional files for replication via CNC or other production processes.
