Abstract
During product development process, several tasks have to be carried out in order to progressively map a set of functions (requirements) to a technological structure. This structure is then designed taking into account a certain number of constraints related to the whole product life cycle (materials, structural analysis, recycling, etc.). In such a context of concurrent engineering this paper focuses on the manufacturing constraints that should be analysed and integrated (synthesis) in the product development. The results then describe what could be the methodology and the model to do so. This work is strongly linked to already-accepted concepts of the scientific community. Indeed, some results on manufacturing process selection exist. Nevertheless they can only be applied once the product form features totally identified. As far as integration is concerned, a lot of product models have also already been proposed in the scientific community, our proposal addresses an evolution of those models toward our manufacturing integration problem. A common model has been specified to link product modelling and manufacturing knowledge modelling. This model is based on an evolution of skin and skeleton concepts. Those concepts have been introduced in many papers for specific points of view modelling but not ever used for manufacturing process selection and integration. Those concepts have been linked to a methodology of selection and integration that can be used at different stages of design process as soon as the first technological choices are realised. Several steps of the proposed methodology are based on manufacturing information management. A structure of this information has then been specified. First, multiple points of view information (functional, structural, structural analysis, etc.), and then manufacturing process information are mapped to the common concepts (skin and skeleton) in order to couple the proposed design solutions to available ones for manufacture.
