Hyundai Motor Group's Digital Measuring Center at the Namyang R&D Center assigns a different measurement tool to each type of object, and its finished-vehicle room uses SCANOLOGY's NimbleTrack-E Gen2 wireless optical 3D scanner to diagnose what whole-car scans flag. Hyundai's Pilot Quality Verification Team says the center measures more than 40 vehicle models a year. A single CMM would need to be set up again whenever the model or measurement area changes, and the team says that way it "could not keep up with the pace of vehicle development."
The sequence follows the build. Doors, hoods, and tailgates are scanned on dedicated fixtures against design drawings before assembly. The body-in-white goes onto cantilever CMMs that share one datum system with production and inspection. Then an automated optical system scans the assembled car. Hyundai says tolerances stack up during assembly, and weight and volume add small deformations that simulation cannot fully predict. When the full-vehicle data shows a deviation, technicians remove the suspect part and scan it with the portable system, then compare the result with design and simulation data.
For quality engineers, the useful detail is that a part can pass on its own fixture and still be the cause of a fit problem on the car. The handheld step answers which part is at fault and by how much, without waiting for CMM time.
NimbleTrack-E Gen2 pairs a 1.4 kg handheld i-Scanner with a 2.6 kg i-Tracker on a tripod. Both are wireless, and the weights include battery and wireless module. The tracker follows the scanner optically, so parts need no reference markers or spray, and a bumper or hood can go straight back on the car. Tracking distance reaches 4.2 m per tracker, and multiple trackers can be combined wirelessly for larger volumes. SCANOLOGY lists system accuracy up to 0.025 mm and volumetric accuracy of 0.072 mm + 0.012 mm/m with photogrammetry, evaluated under ISO 17025 accreditation to VDI/VDE 2634 Part 3. The scanner projects 54 blue laser lines at 120 fps for up to 6.63 million measurements per second, and the i-Probe reaches reference holes the laser cannot see.
All of the center's data lands in one pool backed by its own data center. Hyundai runs two in-house methods on it. DATA-FIT uses measured data to find the best virtual assembly position for doors, bumpers, and lamps. DATA-AUDIT checks interference, mating, and sealing in the digital model, so a car does not have to be taken apart repeatedly.
SCANOLOGY says tracked scanners do not replace the CMM that sets the body datum or the automated cell that captures every finished car. The company argues the same workflow of whole-assembly scan, then part-level diagnosis applies to rail car bodies and aircraft interiors.
