Feasibility of Supply-Chain Data Reuse for MBD

This technical brief documents findings from a National Institute for Standards and Technology (NIST) project that investigates the feasibility of utilizing Model Based Definition (MBD) data through standards-based interoperability. The focus is on how 3D MBD model data can be effectively employed in downstream processes, adhering to ISO standards to enhance manufacturing efficiency while reducing costs. The project highlights the necessity for technical data packages (TDPs) to be compliant with industry standards, such as MIL-STD-31000A, which mandates the delivery of 3D models in compatible formats like STEP or JT. The brief describes various methodologies for data exchange and the implications of MBD approaches in manufacturing and inspection, reporting that significant time savings were observed in coordinate measuring machine (CMM) and first article inspection (FAI) programming when utilizing MBD data directly. Overall, the findings underline the importance of proper planning and validation in achieving compliance and usability of MBD data in supply chains.
