3D scanning for CAD modelling and precision measurement
The 3D optical scanning technology available at RCK Velika Gorica can be used manually with the Atos Q 8M 3D scanner on its mobile stand, where the operator moves the scanner by hand to take scans, or semi-automatically with the GOM ScanCobot (a robotic arm with an integrated 3D optical scanner), where the scanner positions are set by control software that moves the robotic arm. 3D scanning digitises objects quickly and in detail, so it serves many purposes in production: CAD modelling, quality control and analysis of geometric dimensioning and tolerancing (GD&T).
3D scanning for CAD modelling and reverse engineering
The advanced optical system scans objects without contact at high resolution, creating a precise point cloud and a polygon model (STL format). This data is then processed and reconstructed into a parametric CAD model, which is essential for:
- Reconstructing missing or worn parts
- Optimising existing designs
- Digital archiving or modernisation of products (product prototyping)
Precise dimensional measurement (GD&T) with GOM Inspect software:
In addition to conventional measurements, the system allows detailed analysis of geometric dimensioning and tolerancing (GD&T) with GOM Inspect software. This includes:
- Comparison with CAD models and automatic detection of deviations
- Measurement of form, position and tolerances
- Measurement reports in line with industry standards
Compared with conventional methods, 3D scanning delivers faster, more accurate and more reliable results, eliminating human error and enabling complete digital control of geometry.
Industries that use 3D optical scanning include:
- Automotive (fast inspection and dimensional checks of bodywork, chassis and engine parts during production, analysis of component deviations, …)
- Aerospace (inspection of geometric tolerances of critical parts to high safety standards, …)
- Medical (digitisation of implants and prosthetic aids, production of precise orthopaedic and dental implant models tailored to the patient's anatomy)
- Tool making (quality inspection of castings, moulds and complex machine parts, scanning old or worn tools to produce replacement copies, …)
- Cultural heritage and archaeology (restoration and digital archiving of historical artefacts, making replicas of damaged parts, …)
- Entertainment and design (digitising real characters and sets for 3D computer animation in films, video games and industrial design, …)
Precision tactile 3D measurement with CMM technology (Altera C and Camio software)
The 3D tactile measurement technology available at RCK Velika Gorica uses the Altera C coordinate measuring machine. In industry, where micrometre accuracy and reliability are essential, coordinate measuring machines (CMMs) play an irreplaceable role in quality control and dimensional inspection.
The Altera C with integrated Camio software enables high-precision tactile measurement, ideal for demanding production processes.
How does CMM measurement work?
A CMM uses tactile probes that touch the surface of the object, recording the exact 3D coordinates of each measured segment. Camio software enables analysis of form, dimensions and tolerances, ensuring that every product meets its technical specifications.
Where is it used?
CMM measurement is essential in industries where high precision and repeatability are a must, such as:
- Automotive (e.g. checking the dimensional accuracy of engine and body parts, …)
- Aerospace (e.g. inspection of aerodynamic surfaces (wings, fuselage, turbine blades), mechanical parts, …)
- Medical (e.g. measuring implants (prostheses, artificial hips, …) and precision medical devices, …)
- Tool making (e.g. quality inspection of moulds, plastic injection tools and precision parts, …)
Unlike conventional measurement methods, a CMM provides high accuracy, repeatability and automation, which reduces the risk of human error and speeds up production processes.
