Unformatted text preview: ats until every vector exhibits correct function. We demonstrate the algorithm on common mechanical systems. 1. INTRODUCTION We present a tolerance synthesis algorithm for mechanical systems comprised of higher kinematic pairs. Tolerance synthesis is a central part of kinematic synthesis, which is the task of designing a mechanical system that performs a specified kinematic function. Kinematic synthesis is an iterative process in which designers select a design concept, construct a parametric model, and assign tolerance intervals to the parameters. The goal of tolerance synthesis is to derive tolerances that guarantee correct kinematic function at a minimal cost. Overly tight tolerances can necessitate expensive manufacturing processes, whereas overly loose tolerances can lead to unreliable products. The kinematic function of a system is the coupling between its part motions due to contacts between pairs of parts. A lower pair has a fixed coupling that can be modeled as a permanent contact between two surfaces. For example, a...
