Business management · Metrology and Calibration
An uncalibrated caliper, a retouching monitor out of profile, a scale that reads high. The Metrology module controls the whole instrument: range, resolution, maximum permissible error, point-by-point calibration with uncertainty, the certificate on file, a traceable reference standard, checkout and loan, and repeatability and reproducibility studies. Most important of all, a blocked instrument is refused at the moment of measurement, not discovered during an audit.
The problem and the fix
If any of these situations sounds familiar, it is because they happen in almost every graduation company, until the right system comes in.
The calibration spreadsheet exists, but nobody looks at it, and the overdue instrument keeps measuring on the production floor.
Status recalculated every day, an alert before the due date and a usage hold: the overdue instrument is refused at inspection and at production reporting, with the reason on the screen of whoever was about to measure.
The laboratory wrote pass on the certificate, and nobody checked whether the error fits the part tolerance.
Maximum permissible error registered on the instrument and calibration recorded point by point. A point outside the limit fails the calibration even when the certificate says pass, and opens a nonconformity on its own.
The certificate is in a drawer, nobody knows which standard was used, and the audit asks for the traceability chain.
Certificate attached to the record, reference standard registered with its own certificate and a link showing which standard was used in which calibration. The chain opens in one click.
The instrument is gone, somebody took it to the event and nobody knows who has it.
Checkout and return recorded with the person responsible, location and expected return date. A loaned instrument does not show as available to anyone else, and an overdue return takes it off everyone's list.
Two operators measure the same part and get different results, and the discussion turns into opinion.
MSA study with repeatability and reproducibility calculated by average and range and by ANOVA, with the decision recorded: above 30 percent fails, between 10 and 30 requires justification.
In practice
Everyday situations at graduation companies, from the problem to the result, using the modules on this page.
The studio delivers an entire batch with a color cast, and the retouching was approved on the monitor that was wrong.
The monitor is registered as an instrument with a profiling interval, the hold switched on and an owner. Once it expires, the visual color inspection refuses to use it.
The defect stops being created, and the cost of poor quality for that batch ceases to exist.
The laboratory returns the instrument with deviation above the acceptable limit at two of the five points.
The points are entered with reading and uncertainty. The system fails it, does not push the expiry date forward, puts the instrument into maintenance and opens the nonconformity.
The measurements taken with it stay traceable through the inspection, and the decision on what to do with the product is made with data, not from memory.
The auditor picks an instrument and asks for the chain up to the national standard.
The record shows the calibration, the attached certificate, the accredited laboratory with its accreditation number and validity, and the reference standard used along with its own certificate.
The evidence comes out on the spot, with no folder to hunt for and no call to the laboratory.
How it works
Every step is a real module, and what comes out of one goes into the next without anyone typing it again.
