Calibration versus verification
Calibration establishes the relationship between a machine's indications and a reference value, with a stated uncertainty. What most buyers order is a performance verification against ISO/IEC 17025:2017-aligned criteria, or against ASME B89.4.1 by customer preference.
Both are handled the same way here: geometric adjustment where indicated, error-map compensation where the controller permits it, and a certificate that states what was actually done.
What a visit covers
The same sequence applies whether the result is destined for an acceptance test or a routine reverification, and no step is shortened for either one.
- 01
Scale and reader head
X, Y and Z scales are cleaned and inspected; reader head output is checked and adjusted.
- 02
Air bearings and airlines
Bearing condition and supply air quality are checked before any geometric test proceeds.
- 03
Geometry
Straightness, linearity and squareness are checked in the XY, ZX and ZY planes.
- 04
Length measurement error
E0 and E1 tested per ISO 10360-2, 105 measurements across five lengths and seven positions.
- 05
Probing error
PFTU tested on a calibrated reference sphere separate from the probe qualification sphere, per ISO 10360-5.
Sequence of work
- 01
As-found
Geometry and length error are recorded before any adjustment is made.
- 02
Adjustment
Kinematic errors and squareness are corrected where the machine allows it.
- 03
Compensation
Volumetric error map is updated on controllers where OEM access permits.
- 04
As-left
Full verification is repeated and results are issued on certificate.
Why Indianapolis CMM Calibration and Repair
- 01
As-found is never skipped
Impact assessment back to the last passing calibration depends on it.
- 02
Repair and verification together
Probe, scale, air bearing and drive repair are followed by re-verification, not assumed.
- 03
Environment checked first
Thermal soak and gradient are confirmed before test lengths are measured.
