This paper identifies some of the problems and ambiguities with existing standards for establishing datums in manufactured components. Most of the criteria as described in the standards do not uniquely define the datums from measured data points of manufactured features. Three important characteristics need to be validated in establishing datums. By using the computational geometry-based techniques and least squares method, it is possible to provide unique and unambiguous criteria for establishing datums.
