MODEL DRIVEN PRODUCT REALIZATION : A holistic demonstration of model driven product development

Abstract: Model driven product realization is an emerging methodology in industrial scenario. It focuses onusing 3D models in various formats to design, manufacture and inspect a product. The benefits ofthis methodology are improved cross functional interoperability, reliable modeling and simulation,optimized design decision making, improved performance predictability, strengthened collaborative environment and shortened development time. Currently the prominence of 2Ddrawings and its usage is still prevalent in the industries which results in under‐utilization of the presently available CAx systems leading to diminished productivity. This thesis is aimed to demonstrate the capabilities and impact of model driven approach to formulate an efficient product development methodology in a real industry scenario. For achieving the intent a prototype product is considered which is used in suspension system of the research concept vehicle developed by KTH transport labs. The scope includes the industrialization of the prototype resulting in new/final design, process plan, operation plan inspection plan and eventually a manufactured part using annotated 3D models at all stages. It also showcases the process and product feedback methodologies possible by this approach. The foundations for this demonstration are ISO 10303 standard and STEP (standard for the exchange of product model data) application protocols. These define the computer interpretable representation and exchange of product manufacturing information across various domains. There have been considerable advancements in these standards in recent years but a standard way of approaching the model driven product development does not exist. Hence this demonstration enables as a stepping stone for implementation of this approach in real world.
