Mounting
Most accuracy and repeatability problems can be attributed to improper
mounting of the arm. These issues are not always obvious. An
apparently stable mount can actually be moving more than the accuracy
of the device, directly impacting results and causing system
performance degradation.
If using a magnetic mount, check that mating
surfaces are clean and free of debris.
N
OTE: Small metal shavings can cause the FaroArm
to rock back and forth. The magnet will naturally
attract these shavings.
1 Line up front of arm base
with the calibration cone.
2 Open up an X, Y, Z DRO in
CAM2 or another
application.
3 Place the probe in the cone
and hold the FaroArm very
still.
4 Apply approximately five (5)
pounds of force to the base
ring in the direction of the
cone.
5 Note the Y deviation. It
should not exceed 25% of the
FaroArm's accuracy.
6 Apply approximately five (5)
pounds of force to the base
ring 90° away from the
previous direction.
7 Note the Y deviation. It
should not exceed 25% of the FaroArm's accuracy.
8 Apply approximately five (5) pounds of force to the cone.
9 Note the X, Y and Z deviations. They should not exceed 25% of the
FaroArm's accuracy.
