No matter if the objective is to inspect, repair or modify a
components, the challenges remain the same: access to the components and
stability of the measurement setup. The components that require measurement
like impeller blades, guide vanes or casings are always located onsite with
difficult access. To perform an accurate and complete measurement of the
component of interest, that is why we used our non-destructive testing (NDT)
and portable top notch 3D measurement solution: Creaform HandySCAN3D™ metrology-grade 3D scanner. This way, the part can be located
in an unstable environment without it affecting the accuracy. The 3D scan
generated with this method will provide the density of measurement needed for
the complete 3D characterization of the component.
Our client came to us asking if we could reverse model an impeller,
the catch was that it was only available for one day and it had to go back into
the field as it was a working component in the facility. Our technical
engineer went to the facility and 3D scanned in onsite, generating a CAD
file so that a new pattern can be made to make another one.
We were faced with the need to be quick, accurate and produce a file that was clean and ready to use. Due to its impressive portability, its small size and its on-part reference, the HandySCAN 3D can perform the acquisition directly on-site!
Why the HandySCAN 3D Solution?
- Metrology-grade measurement for aircraft preservation: Our 3D scanner has a resolution of up to 0.100mm (0.0039 in.) and accuracy up to
0/025 mm (0.0009 in.) with a traceable certificate and high repeatability.
- Speed: Our scanner is the quickest and most reliable surface
analysis device accessible on the market. It is 80 times faster than the
traditional technique.
- Live visualization and portability: Our portable and handheld scanner is extremely light, weighing in at less than a
kilo, and perfect for use on-site.
- Intuitive pass/fail assessments: With its
real-time software visualization, and intuitive design, our non-destructive
testing solutions provide shortened learning curves and nominal operator
training in order to ensure accurate results.
- VXmodel: The HandySCAN 3D scanner was the ideal
device for this case, as it can provide complete and accurate
mesh models. VXmodel enables you to easily generate NURBS surfaces for
characterizing freeform regions. Primitive entities can be easily extracted
from the mesh to complete the design in a CAD software. The VXmodel can
generate solid models directly on the scan data. That enabled us to use the
data live on site. The Transfer-to-CAD option enabled us to export the scanned
data to CAD standard format, making it readily available to the designer.
