Verification, adjustment, and what each artifact detects
Calibration establishes readings against reference values with a stated uncertainty. What most shops need, and what this covers, is performance verification: confirming the machine still meets its stated specification, then adjusting geometry and the volumetric error map where the controller supports it.
For large-envelope bridge and gantry machines common in machinery and heavy equipment building, verification is normally performed on-site, at the foundation the machine already sits on.
What a visit covers
Scales, geometry, probing and length measurement error are checked in sequence, with as-found results recorded before adjustment.
Scale and reader head
X, Y and Z scales are inspected and cleaned; reader head output is checked and adjusted.
Air bearings and airlines
Bearing preload and supply air quality are checked against machine tolerance.
Geometry
Straightness, linearity and squareness are measured in the XY, ZX and ZY planes.
Length measurement error
E0 and E150 are tested per ISO 10360-2, 105 measurements across five lengths, three repeats, seven positions.
Probing error
PFTU is tested per ISO 10360-5 against a dedicated calibrated sphere, separate from the qualification reference sphere.
Sequence of work
Thermal soak
Artifacts and machine are allowed to stabilize to the specified environment before testing begins.
As-found test
Length measurement error, probing error and geometry are recorded before any adjustment.
Adjustment
Geometry is corrected and the volumetric compensation map updated where the controller permits it.
As-left verification
The same tests are repeated and results issued against the applicable specification.
Why Milwaukee CMM Calibration and Repair
Large-envelope experience
Weldments, frames and gearbox housings are within the working volumes routinely verified here.
Build-to-print aware
One-off and low-volume machinery parts are the norm, not high-volume PPAP throughput.
Repair through re-verification
Crash recovery and component repair are followed by a full as-left test, not a partial check.
Coverage across Wisconsin and the Greater Midwest
On-site service is scheduled across southeastern and eastern Wisconsin. Ship-in service is available outside that radius by arrangement.
