- Abstract:
- A highly accurate roundness measuring instrument and the calibration system of its probe were developed. The international round robin comparison of form measurement organized by the CIRP was carried out from 1996 to 1998. The measuring results obtained by using this instrument and system correspond satisfactory to the results by PTB with very small measurement uncertainty. For example, the obtained roundness of zerodur sphere with 50 mm diameter is about 179 nm with 9 nm (k = 2) in uncertainty of measurement, while the corresponding result by PTB is 184 nm and 10 nm respectively.
