Multi-scale modelling for knowledge capitalization and Design For Manufacturability

Abstract

The development of analytical technologies and simulation tools used in the PLM increase day by day. There is a lot of data, information and knowledge associated to the product and its manufacturing plan. Precisely, during the process of design for manufacturing, the extensive number of solutions contains a lot of behaviours, associations, aspects and inputs to consider. For this reason, this paper aims at proposing a new multi-scale model as a way to provide a better structuring, better perception and better description of the many aspects involved in a product design and its manufacturing plan. The product and manufacturing plan models are based on different scale representations, characterized through “representation axes”, where the knowledge is decomposed and commit. At the same time, manufacturing knowledge is implemented to bring and evaluate the coherency among the model features.
