ABSTRACT:
A tolerancing method includes modeling positions and sizes of apertures in an assembly of parts. The parts are best-fit together. Aperture position in the parts is statistically varied. The best-fitting and statistical variations of the aperture positions are repeated for a statistically significant number of trials to create a statistical model. The size of fasteners for assembly through the mating apertures may be selected as determined in the statistical model.
