典型航天机械产品几何量批量测量结果不确定度方法

摘要

圆筒类机械产品在航天行业占有较大比重，且适用于批量测量。为了评定测量结果的质量，对某批零件采用坐标测量机进行自动批量测量试验，并详细介绍了测量结果不确定度的评定方法。%In the aerospace industry, amounts of the mechanical components are columnar and fitted to be multi-batch measured. In order to evaluate the performance of the measuring results, the automatic batch measuring experiment of the appointed components is implemented us⁃ing the coordinate measurement machine (CMM). Moreover, the evaluation of uncertainty about the results is put forward.
