L'auteur - Bernard Anselmetti
Bernard Anselmetti est professeur à l'IUT de Cachan (université Paris-Sud) où il enseigne la fabrication mécanique, le tolérancement et la métrologie. Directeur adjoint du laboratoire universitaire de recherche en production automatisée de l'ENS Cachan (LURPA), ses recherches portent sur la formalisation des techniques de tolérancement et de fabrication.

La spécification géométrique des produits (GPS) est une méthode normalisée qui permet de définir, sur le dessin de conception d'une pièce, toutes ses caractéristiques géométriques et fonctionnelles : forme, dimensions, état de surface, relations entre les éléments, etc. 

This textbook teaches the user how to create tolerance stacks using the ‘Two Column’ method. The book teaches how to establish a stack path, ground out the parts, and create a stack using all geometric characteristics. Fundamental concepts of GD&T are reviewed when introducing each characteristic.

This text-workbook/answerbook explains the process of Tolerance Stack-Up Analysis for assemblies using both plus and minus and geometric tolerances.

 It explains pertinent aspects of Geometric Dimensioning and Tolerancing, then proceeds to teach a sound, logical, mathematically-reliable methodology for calculating tolerance stack-ups. This text is comprehensive, yet very easy to understand and follow from lesson to lesson. 

The ability to perform a fast and accurate tolerance analysis is often the mark of the best mechanical design engineers. 

Designs that fit together and function properly the first time don't "just happen". They are intentional bi-products of tolerance analyses conducted by a careful engineer. With a brief, no-fluff introduction to the thought process and principles that govern tolerance analyses, you will set yourself apart as someone who has what it takes to Make It Fit.
