Measurements 1. Gap - the distance between
the left and right edges of the gap. Determination of the edge of
the gap is
critical
to the measurement. Edge selection can be made visually by the operator
in on-screen measurements. In automated measurements, edge selection
is made using a number of different methodologies.
2.
Flush - the height difference between the left and right panels on either
side of the gap.
Industry Examples 1. Automotive
- post-production inspection of panel fit-up on auto and truck bodies.
2. Aerospace - pre-weld
plate fit-up.
3. Pressure Vessels - inspection
of panel seams.
4. Manufacturing -quality
check of machined gaps in parts.
Controllers
and Sensors The field-of-view of the
sensor should be sufficient to capture the maximum width of the gap plus
enough of the surface on either side of the gap to establish the flushness.
All controller and sensor combinations would be candidates for use on this
application. Sensor stand-off's that guide the sensor into position
over the gap would be important to the ease of use and repeatability of
results.
