Abstract :
The evaluation of measurement uncertainty is an important part of the new generation geometric products specifications (GPS). At present, coordinate measurement only give examine result of plane to plane parallelism, and fail to give uncertainty problem of examine result. According to basic principle of two planes least-square verification and ISO/ TS 14253 - 2 to give transfer formula of uncertainty, combined with evaluation and simplification of synthesis uncertainty, the paper put forwards a kind of uncertainty calculate method of two planes parallel coordinate measurement. The experiment show that the two planes parallelism certification based on the proposed method can meet the requirement of the new generation GPS standard, and the certification result is standard and reliability.
