Calibration Versus Verification
Calibration establishes the relationship between the machine's readings and a reference value, with a stated uncertainty. Performance verification confirms the machine still meets a stated specification, usually ISO 10360-2 or ASME B89.4.1.
Both terms get used loosely on the shop floor. The certificate should state which one was performed, and against which standard.
What a Visit Covers
Whether the request comes from a stamping plant's fixture room or a tier supplier's quality lab, a verification visit follows a fixed sequence.
Scale and reader head
X, Y and Z scales are inspected and cleaned; reader head output is checked and adjusted.
Geometry
Straightness, linearity and squareness are checked in the XY, ZX and ZY planes.
Length measurement error
ISO 10360-2 E0 and E150 testing at 105 measurements across five lengths and seven positions.
Probing error
ISO 10360-5 PFTU testing on a calibrated test sphere separate from the qualification reference.
Air bearings and drives
Air supply, bearing preload and drive response are checked ahead of geometric adjustment.
Sequence of a Verification
Inspect
Scales, reader heads and air bearings are checked before any measurement is taken.
Test
Length measurement error and probing error are run against the applicable standard.
Adjust
Geometric adjustment and error-map update are applied where the controller supports it.
Verify and certify
As-left results are recorded and the certificate is issued.
Why Detroit CMM Calibration and Repair
As-found and as-left
Both results appear on the certificate wherever adjustment occurred.
OEM-locked maps handled
Error-map access is confirmed on the controller before the visit is scheduled.
Repair on the same visit
Probe head, scale, air bearing and drive repair reduce a second trip.
Coverage across Michigan and the Greater Midwest
On-site scheduling and travel terms vary by location; confirm coverage and lead time when a quote is requested.
