Geometric tolerancing explained by means of concept maps

Knowledge plays a fundamental role inside the industrial reality, being closely connected to the efficiency of the entire lifecycle of a product. In this work the authors present the use of the Concept Map as a form of simplifying, storing and communicating the technical concepts that stand behind a normative. The normative of reference is the one related to the Geometric Dimensioning and Tolerancing (GD&T) that expresses a language to define tolerances in mechanical technical drawings. The objective of this work is to create a set of Concept Maps that permits to study and to communicate the rules defined in the GD&T, in order to support the designer during the process of defining geometric tolerances. The resulting Concept Map will be freely available over the Internet.
