A Reverse-Engineering Approach for the Management of Product Geometrical Variations during Assembly

Abstract : One of the major challenges for the aerospace industry is to manage a range of complex products during their manufacturing and assembly process. Digital Mock-Ups (DMU) are nowadays extensively used as supports of information during the afore-mentioned phases. In this paper we introduce the concept of updated DMU which actually reflects the product being assembled. For this purpose, the nominal product geometry needs to be updated in order to reflect the as-built geometry of the prod-uct's components at a given step of its assembly. The geometry of the next components to be assembled, called interface components, are consequently updated in order to adapt to geometrical variations, while the rest of the DMU stays in its original as-designed configuration. A comprehensive method to update the DMU from its as-designed configuration to reflect the actual configuration of the product being assembled is thus proposed. To this end, a framework inspired from the Reverse-Engineering field is developed, then assessed thanks to a simple case study.
