3 Caliber calculation

In mass production and mass production, calibers are used to control the accuracy of sizes. Gauges for inspection of holes are called plugs, for inspection of shafts - staples. Calibers are made in a set of pass-through (PR) and impassable (NOT) calibers. When checking the part with calibers, it (part) is recognized as suitable if the through caliber passes, and the impassable one does not pass through the surface to be checked .

If the pass gauge does not pass, then in this case there is a recoverable marriage. If the impassable gauge passes, then in this case there is an uncorrectable marriage .
