Testing was
conducted by Fiat in Turin with the assistance of
Microsystem, Raindrop Geomagic’s Italian distributor. Six
copies of an underbody sheet metal part containing slots and
holes were tested by two operators, with three runs for each
part. A total of 110 characteristics were inspected.
Tolerances were well within ANFIA specifications and
repeatability and reproducibility (R&R) percentages were
much higher than the association’s minimum requirement.
While results
for the digital process are comparable to those for
traditional CMM, the newer process offers major advantages.
The 3D scanner can capture thousands of points in a single
scan; the CMM system collects one point at a time. Multiple
characteristics from the scan data can be analyzed by
Geomagic Qualify without having to measure the part again.
Geomagic Qualify also extracts more information from the 3D
scan data and enables procedures such as GD&T analysis.
Fiat’s tests
follow Geomagic Qualify receiving the highest accuracy
certification from Physikalisch-Technische Bundesanstalt (PTB),
Germany’s technical authority for metrology and physical
safety engineering, and successful gauge R&R testing by
Honeywell and other major turbine manufacturers. “We are
witnessing a major shift in inspection to a digital process
that is easier, much faster, and more comprehensive than
traditional methods, while meeting or exceeding
repeatability and reproducibility standards,” says Alberto
Griffa, senior product manager for Geomagic Qualify.
