Résumé en anglais

Increasingly, coordinate measurement techniques are used to ensure that mechanical parts conform to their geometric specifications. The analysis of the possibilities of the software in use brought to light an important number of tools, which however are not always adapted to the problem which is to be solved. Generally these tools only give one approximate answer to the problem ser out by the verification of the dimensional and geometrical specifications. An indept study of the standards lead to be presentation, in this paper, of the problem typology. The two aspects of the verification of the specifications (measurement and control) will be presented and also the implication which these have on the solution algorithms. Finally, an attempt to define new processes giving the true value of the size to be verified is proposed. These proposals will be illustrated by an example, and the numerical results will be analysed and compared.< Réduire
