Geometric Dimensioning and Tolerancing is used to describe the allowed feature variations regarding the product design. Tolerance specification is important in many stages of all phases on product development. The product development engineering need to define the symbols to use on the Feature Control Frame of every component. Since the component function has an increment on its complexity year over year, it is not trivial to define those symbols anymore. The determination of dimensional tolerance shall be preceded by careful specification of the types of tolerance and symbols that will be applied in controlled features. Poor tolerance specifications can increase the production cost, require late product changes or lead to legal issues. In this scenario, this paper presents a method to evaluate this engineering information for a few number of GD&T technical experts in a specific system, like chassis or powertrain, and translate it into dimensional tolerance requirements to support the tolerance specification process using fuzzy logic. Also, the method suggests the best set of symbols based on the feature geometry, assembly and function analysis and classify these features to generate significant information on the automotive industry.
