The Status of Manufacturing Process Simulation and NAFEMS – MANWG

This presentation was made at the NAFEMS Americas "Creating the Next Generation Vehicle" held on the 14th of November in Troy.

The automotive engineering community is now confronting the largest technology transformation since its inception. This includes the electrification of powertrains for more efficient consumption and cleaner emissions, the reinvention of the battery with fast wireless charging capabilities and finally the advent of a fully autonomous vehicle. Compounding to these technology changes, the automotive companies design verification process is moving away from a major reliance on physical testing to almost a full virtual simulation product verification process.

Resource Abstract

This presentation starts with an overview of manufacturing process and system and discusses their common physics phenomena and performance parameters that designers are interested in. Then, a generic definition of manufacturing process and system simulation is presented, which defines manufacturing simulation into two categories. The first category is manufacturing system simulation that aims to analyze the systematic performance of a manufacturing system that is a material flow system which consists of several manufacturing processes. The second category is manufacturing process simulation that is to analyze an individual manufacturing process which consists of one or more physics phenomena of the material transformation. After a brief introduction of manufacturing system simulation, the requirements and challenges of manufacturing process simulation are discussed, such as the raw material property input data, process uncertainty and multiscale modeling. To address these challenges three hot frontiers of manufacturing process simulation are introduced: Multiscale Modeling for ICME – Integrated Computational Material Engineering, Uncertainty Quantification for “the last mile” improvement of manufacturing process simulation and Digital Twin for product real time whole life monitoring and control from its birth (manufacturing process) to its decommissioning and recycling.



In addition, the speaker will talk about the NAFEMS – MANWG, its goals, subgroups and recent activities, especially how NAFEMS can help industrial simulation practitioners via promoting effective and efficient manufacturing simulation practices.
