在投影仪上模拟最小实体实效边界及其测量不确定度评定

BUILDING MINIMAL SUBSTANCE′S VIRTUAL BOUNDARY ON PROJECTOR AND ESTIMATING THE MEASUREMENT UNCERTAINTY

对于厚度相对较小或定向误差可忽略的注有○L定位公差的被测件,在投影仪上模拟最小实体实效边界是一种符合最小实体要求定义的测量方法.本文通过实例论述了该测量方法及其测量结果不确定度的评定方法.

For a work piece whose orientation error is ignorable,building a minimal substance′s virtual boundary on a projector represents a measuring method complying with the required definition of the minimal substance.In this paper,this method is illustrated and its measurement uncertainty is assessed.
