We utilize analog anvil micrometers to measure wall thickness of plastic tubing. To set the gage, our team members workhold a gauge pin close to the inner diameter of the tube to support appropriate measurement. Once gage is setup the micrometer is adjusted to rezero to support accurate readout for the operator to eliminate/reduce measurement error.
In our recent AS9100 audit questions were raised regarding the safeguarding of calibration on this gage. Calibration of this gage is technically only verifying smooth rotation and to detect wear on the measurement surfaces. In essence a verification not calibration. How have other teams managed compliance to safeguarding on hand tools that are designed to be rezeroed to support accurate measurement reading by operators?
