Calibration versus verification
Calibration establishes the relationship between a machine's indications and a reference value, with a stated uncertainty. What is usually sold as CMM calibration is a performance verification against ISO 10360-2 or ASME B89.4.1, often combined with adjustment.
Both routes are offered. Older machines are frequently held to B89.4.1 by customer preference; newer installations verify against ISO 10360-2 directly.
What a visit covers
Scales, geometry, probing and length measurement error are checked in sequence, with results recorded before any adjustment is made.
- 01
Scale and reader head
X, Y and Z scales are inspected and cleaned; reader head output is checked and adjusted.
- 02
Geometry
Straightness, linearity and squareness are checked in the XY, ZX and ZY planes.
- 03
Length measurement error
E0 and E150 tested per ISO 10360-2, 105 measurements against stated MPE.
- 04
Probing error
PFTU tested per ISO 10360-5 on a dedicated calibrated test sphere.
- 05
Repair scope
Probe heads, air bearings, drives, counterbalance and controller retrofit after crash or relocation.
Sequence of a calibration visit
- 01
Thermal soak
Artifacts and machine are allowed to stabilize to room temperature before testing begins.
- 02
As-found testing
Geometry, length measurement error and probing error are recorded before adjustment.
- 03
Adjustment
Geometric compensation and error map updates are applied where the controller supports them.
- 04
As-left verification
Tests are repeated and results issued on a certificate with stated uncertainty.
Why Louisville CMM Calibration and Repair
- 01
As-found recorded first
Out-of-tolerance findings are documented before adjustment, supporting a reverse-traceability review.
- 02
Both standards offered
Verification is available against ISO 10360-2 or ASME B89.4.1 depending on the certificate the machine was built to.
- 03
Repair alongside calibration
Air bearings, drives and probe heads are serviced in the same visit where practical.
