Calibration versus verification
Calibration establishes the relationship between indicated and reference values with a stated uncertainty. What most shops order is performance verification: a pass/fail test against ISO 10360-2 or ASME B89.4.1, run alongside geometric adjustment.
Where the controller allows it, the volumetric error compensation map is updated after adjustment. OEM-locked maps limit what can be changed in the field.
What a visit covers
Cleaning and inspection open the visit; an as-left certificate closes it, with geometry and length measurement error testing in between.
- 01
Scale and reader head
X, Y and Z scales are cleaned and inspected; reader head output is checked and adjusted where needed.
- 02
Air bearings and airlines
Bearing condition and supply air quality are checked before geometry testing begins.
- 03
Geometry
Straightness, linearity and squareness are checked in the XY, ZX and ZY planes.
- 04
Length measurement error
105 measurements across five test lengths and seven positions, per ISO 10360-2.
- 05
Probing error
Tested per ISO 10360-5 against a calibrated test sphere separate from the qualification reference sphere.
Sequence of a visit
- 01
Thermal soak
Artifacts and machine are allowed to stabilize to the specified environment before testing starts.
- 02
As-found test
Length measurement error and probing error are recorded before any adjustment is made.
- 03
Adjustment
Geometric correction and compensation updates are applied where the controller supports them.
- 04
As-left certificate
Final results are issued with reference standards, uncertainty and the decision rule applied.
Why Minneapolis CMM Calibration and Repair
- 01
As-found is preserved
Data is captured before adjustment so an impact assessment can be run if needed.
- 02
Repair and calibration together
Probe, scale, bearing and drive repair are handled without a second site visit.
- 03
Environment checked first
Room temperature and gradient are confirmed before an acceptance test is scheduled.
Coverage across Minnesota and the Greater Midwest
