Interference method of measuring the diameters of holes by certified plug gauges
The method developed provides the highest (for comparable methods) accuracy of measuring the diameters of holes (the error does not exceed 0.1 μ) with the use of relatively simple and accessible measurement means.
The method can be used for certifying standard ring gauges used as the reference measures when giving size to ring gauges of a lower accuracy.
For the wide introduction of this measurement method into control practice it is expedient to develop and produce an industrial model of an instrument based on the experimental measurement device and to organize the production of ring and plug gauges for it.
The ring gauges for this measurement method should be made of a transparent and sufficiently hard and stable material-quartz, glass, pyroceramic, etc.
