Practically, some of the resistances will be strain
gages, ideally from the same manufacturing batch, and some will be precision fixed-value resistors.
In the course of a year, the
Gages travel far and wide, but they are always happy to return to North Grafton.
Avoid rejecting good pieces or shipping bad pieces because of an inaccurate
gage reading -
Gage Manager tracks every possible piece of information about every
gage, to ensure accurate and consistent measurement.
Note that both the standard
Gage R&R calculations and the proposed MSV are shown for comparison purposes, though the percent operator variation in the MSV calculation does not have the part correction that is shown for GR&R.
Evaluating the accuracy of foundry
gage equipment provides better understanding of a casting's true conformance to requirements.
Gage calibration history should be recorded on DA Form 3023,
Gage Record Card.
That way when one set of
gages has to go to TMDE for calibration, you still have the other set available and your machine guns are still mission capable.
Digital bore
gages are available in two basic formats: traditional internal micrometer style or electronic pistol grip
gages.
Over the long term, temperature will cause uncorrected
gages to produce varying dimensions.
Many units probably have never had the
gages calibrated.
Gagemaker, a manufacturer of precision dimensional inspection equipment, designed the Functional Thread Roll
gages to inspect "thread element variation," which satisfies System 23 requirements.
Variable
gages come in a variety of different types, such as hand micrometers, bench fixture
gages, automatic machines, or coordinate measuring machines.
