Current statistical formulas used to predict process capability from continuous data regard all dimensional specifications as having constant tolerance while many of them are variable. ... Geometric tolerances and datum feature designations followed by the tolerance modification symbols ? or ? permit a variable "bonus"

In this paper, we develop a geometric theory for establishing DRFs. The theory is based on the observation that a datum feature such as a plane, a cylinder or a sphere has a symmetry subgroup G_0 under the action by the group SE(3) of rigid motions in R^3. Thus, the configuration space of a datum feature can be...

Referencing geodetic coordinates to the wrong datum can result in position errors of hundreds of meters. Different nations and agencies use different datums as the basis for coordinate systems used to identify positions in geographic information systems, precise positioning systems, ...
