| Abstract: | Assessing methods for uncertainty in measurement of cone-shaped thread base level pitch diameter are researched and analyzed,on the basis of which the source,the measurement method and the computing formula of uncertainty in measurement of base level pitch diameter are particularly dissertated. By means of experimental data, the paper analyses assessing method of uncertainty in measurement of cone-shaped thread base level pitch diameter. Researching conclusion indicates that the assessing method is of both integrality and singularity in theory and maneuverability in practice. |
