Unformatted text preview: arameters. Tiny steps are required because the kinematic function can vary suddenly or even discontinuously. We limit the search to parameter values that maximize the variation of one or two contacts. We explain the mathematical and empirical rationale for this heuristic below. The input to our algorithm is a parametric model of a mechanical system (part profiles and system configuration) with initial tolerance intervals for the parameters. The output is revised tolerances that guarantee correct kinematic function for all system variations. The algorithm consists of a three-step cycle that detects and eliminates incorrect system variations. The first step finds vectors of parameter values whose kinematic variation is maximal. The second step tests the vectors for correct kinematic function. The third step adjusts the tolerances to exclude the vectors with incorrect functions. The cycle repeats until every vector exhibits correct function. The algorithm builds upon our prior work in mechanical design with configurati...
