Why Calibration is Why Calibration is Important: Important:
5 Areas of Concern5 Areas of Concern• The consequences of infrequent calibration
• Why we calibrate• When calibration alone isn’t enough • Monitoring machine accuracy in-
between calibrations• Who should calibrate your CMM

The Consequences of The Consequences of Infrequent CalibrationInfrequent Calibration
• Machine out of calibration can create havoc in manufacturing process
• Coordinate measuring machine is no longer trusted as a reliable source for measurement.

Why We CalibrateWhy We Calibrate
• CMMs drift from the original manufacturer settings over a period of time
• Changes can take effect as soon as one week after a calibration!
• an annual health check and machine calibration are recommended

When Calibration Alone Isn’t When Calibration Alone Isn’t EnoughEnough
• A combination of calibration, service and adjustment of the map is most desirable
• It will tell you how far the machine has drifted since last calibration and prevents major breakdowns
• This type of comprehensive calibration will cost more money saves you money & anguish

CalibrationsCalibrations• Regularly perform interim checks on your measuring devices
• Maladjusted probing is the most frequent source of measurement problems
• Minor collisions with parts probably go unreported
• Perform interim check with Renishaw Machine Checking Gauge

Who Should Calibrate Your Who Should Calibrate Your CMMCMM• Select an ISO 17025 accredited
calibration company• This means that the calibrator has
equipment and procedures traceable to a national standard

SummarySummary
• A machine out of calibration or one that is not repeatable can create havoc in your manufacturing process
• Good parts are quarantined or scrapped, out of tolerance parts are shipped to your supplier.
• Go the extra mile: calibrate annually with a p.m. visit and map adjustment, perform interim checks weekly
