    Notes: Tolerance stack analysis involving geometric characteristics is usually difficult as it involves numerous rules and conditions. Users need to acquire an adequate knowledge of geometric dimensioning and tolerancing before making any attempt at the computation of tolerance stack analysis problem. Conventional stack form methods are very widely used in tolerance stack analysis, but the computation requires tedious work with numerous rules to remember that often complicate the problem and confuse the user. A need therefore arises to simplify the tolerance stack methodology. This paper presents a straight forward, easy-to-use graphical approach known as the "Catena" method for tolerance stack analysis, involving geometric characteristics in form control – flatness, straightness, circu-larity and cylindricity. Three examples are given to illustrate the effectiveness of the proposed method. No complicated mathematical formulae are required in deriving the solution.

    Applying the Coordinate Tolerance System to Tolerance Stack Analysis Involving Position Tolerance (1999)
    Springer

    Notes: Geometric dimensioning and tolerancing (GDT) has been playing an important role in specifying the geometry of part features during the product design stage. Tolerance stack analysis is then used to study the conformity of the parts to the tolerance zone. Performing stack analysis is time consuming because geometric tolerances are complex to compute. This paper presents a technique to formulate the bonus and shift tolerances (due to positional callout) and convert them to equal bilateral expressions as in a coordinate tolerance system. An example is used to demonstrate the effectiveness of the expressions. The usage of the expressions is less conceptual and this makes the application simple and direct. Most importantly, the results are shown to be accurate and reliable.
