偏梯形螺纹中径牙厚样板校准方法及测量不确定度评定

摘要

文章研究了基于光学三坐标测量机自动对焦、编程对偏梯形螺纹中径牙厚样板进行校准的方法。经大量试验验证及相应测量不确定度评定，结果表明，该方法可完全满足JJF 1063－2000规范中所述偏梯形螺纹中径牙厚样板的校准和溯源要求并优于传统校准方法。%The calibration method for buttress thread thickness template was studied based on the function of auto focusing and programming of OGP.A large number of experimental verifications and uncertainty evaluations were done ,the results showed that this calibration method can meet the requirement of JJF 1063-2000 for thread thickness template 's calibration and traceability , and also be superior to the traditional calibration method .
