Mechanical Gauging (Gauges by Attributes)
Mechanical gauging is performed by means of mechanical instruments (gauges by attributes) that provide measurement results not as a numerical value, but a good/scrap status.
None of them have electronic units.
These instruments are:
- Go - no go gauges:
- Smooth plugs for I.D.
- Smooth snap gauges and rings for O.D.
- Plugs and rings for threaded or splined diameters
- Fixtures (dog houses and layon gauges) with mechanical pins
- Masters and master gears
