The Product Modelling and Realisation Group at the IIA Research Center in Helsinki University of Technology conducts research on a wide range of product modelling and its applications in design and manufacturing. The present work convers in particular the application of product modelling for manufacturing preparation. We have built a feature-based modelling system ExtDesign, and associated it with a prototype process planning system MCOES which is specifically intended for shopfloor use in a limited-function factory. The emphasis is on providing very rapid turnaround of correct NC programs, and natural interfaces for factory personnell in order to maintain the manufacturing models that form the basis of the system. This work has been linked to factory modeling and simulation in the GNOSIS test case of IMS, the international research program on Intelligent Manufacturing System. Our interest also covers early design stages of artifacts. Again in GNOSIS, work on symbolic assembly models and physics-based simulation was carried out. Present plans include extending this work to design process and rationale capture to support transfer of the results of a product development process to operative product configuration systems.
