Mathematical Model for Assembly Tolerance Consistence Evaluation

Abstract

An assembly is described by a geometric model of its parts and their relative placement. Assembly tolerances are the result of parts of varying shape and size being put together to make the finished product. This paper considers the case where parts have tolerance geometry. Its main contribution is to use a tensor space to describe assembly features. The mathematical models are developed. The proposed approach is based on assembly feasibility analysis of shaft and hole features.
