Abstract
A profile's deviation zone cannot be computed from the Euclidean distances of the measured points to a substitute geometry alone, without regard to the tolerance zone the profile actually has to fit. Ahmad Barari demonstrates why the desired tolerance zone belongs in the estimation, then presents a best-fit method that complies with the designed surface's tolerance requirements, and a customised version that builds the substitute geometry so as to minimise both the residual deviations and the additional manufacturing needed to correct the measured surface.
