Laser-interferometric device for calibration of ring gauges

Bartl J., Fíra R.

The measurement of the diameter of cylinder bores is a specific problem of the length metrology. In practice, this operation is realised using three-pointed bore gauges – inside micrometers. The ring gauges-setting rings are used for testing of the inside micrometers. Such ring gauges are manufactured from the wear resistant steel or zirconium ceramic with diameter tolerance of 1 mm and shape tolerances according to DIN 2250. Since the setting rings of highest accuracy are the reference standards of the second order, it is necessary to carry out their precise calibration. This article describes the optical design of a device for the calibration of ring gauges
