Patent ID: 7979236

Claim:
A computer-implemented method for analyzing tolerances for a plurality of features for an object, the computer-implemented method comprising: creating a framework from the plurality of features for the object; fitting the framework to a plurality of manufactured internal features for the object based on the plurality of features to form a fit framework; forming, by a processor of a computer, a plurality of remaining clearances by subtracting each of a plurality of virtual condition sizes associated with the plurality of manufactured internal features from each of the plurality of manufactured sizes for the plurality of features to form the plurality of remaining clearances, wherein each of the plurality of virtual condition sizes is calculated by subtracting one of a plurality of geometric tolerances from one of a plurality of specified maximum material sizes; forming, by the processor, a plurality of remaining clearance features from the plurality of remaining clearances, each of the plurality of remaining clearance features including a circle with a diameter substantially equal to a corresponding remaining clearance; positioning the plurality of remaining clearance features around a single true position; identifying a common region from between the plurality of remaining clearance features positioned around the single true position; and identifying a minimum remaining float from the common region.
