Theoretical Tolerance Stackup Analysis Based on Tolerance Zone Analysis

In this paper, both dimensional tolerance stackup and geometrical tolerance stackup in one-, two-, and three-dimensions are theoretically analysed. The tolerance analysis in this study is based on the analysis of tolerance zones. The manufacturing errors are classified into two general types, locating errors and machining errors. Generative formulation of tolerance stackup is explored. A simulation example of 3D geometrical tolerance stackup is illustrated.
