Chapter 5: Accuracy
If any test fails, print the results and repeat the calibration two more times. Print
all of the results and contact FARO’s Customer Service by
Phone, Fax or E-Mail.
See “Technical Support” on page 161.
Repeatability
Perform the Single Point Repeatability Test to check repeatability (SPAT) of the
Quantumusing a hole or a cone. You must use a firmly secured object with a hole
at least 1mm smaller than the ball probe. If a cone hole is used, extreme care
must be taken to ensure that the probe is seated at each “measurement.”
Use a calibrated ball probe. See “Installing Probes” on page 19 and “Probe
Compensation” on page 59.
Run the Single Point Articulation Test (SPAT). See “Single Point
Articulation Test (SPAT)” on page 138.
Volumetric Accuracy
Perform a Sphere to Sphere, or Point to Point length measurement in order to
certify the volumetric accuracy (E
Uni) of the Quantum. This should be done
using traceable length artifacts, which are measured at various locations and
orientations throughout the working volume of the Quantum. This test is a
method for determining articulating measurement machine accuracy.
Use a calibrated ball probe. See “Installing Probes” on page 19 and “Probe
Compensation” on page 59.
1. Measure points on each feature, from multiple directions. Ensure that
you digitize points on the entire Sphere surface.
2. Make sure that you move the joints of the Quantum while measuring the
points.
3. Do not digitize a point if any of the encoders reach their end stop. See
“Error and Status Indicators” on page 37.
4. Avoid a joint position where a degree of freedom is lost in the Quantum.
See “Loss of a Degree of Freedom” on page 117.
