Single-sided sampling measurement for large solids of revolution and measurement uncertainty of cylindricity

In this paper, the precision of single-sided sampling measurement for large-scale solids of revolution was researched, in which only half of the surface was measured and laser trackers were expected to be used as measurement equipment. A cylinder was taken as example to be measured repeatedly in SA (Spatial Analyzer) software by its secondary development and simulation techniques. Monte Carlo method was used for evaluation of measurement uncertainties of cylindricity. Then some uncertainty results of different sampling strategies were compared and points number' influence on uncertainties were researched too.
