APPROACH TOLERANCE IN THE ASSEMBLIES OF EVOLUTIONARY HYBRID PROTOTYPES

摘要

A new answer is proposed to replace the traditional "one shot" prototype (manufactured inone piece with one process): the hybrid rapid prototype. It is used to highly reduce time,cost and increase reactivity during the development times of new products.The part is decomposed in several components which can quickly be changed and can bemanufactured with a process the most adapted.The main objective of the presented method is to propose an available technologicalassembly between the different components of the part in the respect of technological andtopological function, and initial tolerance.Using a graph of representation, fuzzy logic and a tolerance point of view, some entities areassociated with a CIA (Assembly Identity Card) in accordance with evolutionary andmanufacturing analysis. This work will be illustrated by an industrial tooling for plasticinjection.
