Three-Dimensional Model for Manufacturing and Inspection

Publication Details

Abstract

Three-dimensional model-based engineering (MBE) along with quality information framework (QIF) is an approach to product design, manufacturing, and support where a digital three-dimensional representation of the product serves as the normative source for information communicated throughout the product’s lifecycle and supply chain. MBE simplifies data management and provides a more powerful communication medium than 2D-based environments. This is not just using a model for reference or a visual aid. The model will be the definition for the parts being manufactured, inspected, and built into full engines. The use of two-dimensional prints will be outdated and a culture change will be needed to embrace this change. Many organizations are implementing MBE and are using the technology to produce aerospace products. Manufacturing and inspection functions are dependent on the models from cradle to grave of the products lifecycle. These smart models will have all of the necessary dimensional metrology interoperability, GD&T encoded, and product manufacturing information (PMI) data all in a standardized format associated within the model. This will allow for a model that has fewer errors and greater functionality with manufacturing and inspection systems. The information included in the model-based definition (MBD) will be part of the QIF. The QIF fully defines quality measurement plans, measurement results, measurement rules, measurement resources, and results analysis. This, combined with the PMI for manufacturing, will provide a comprehensive MBD that can be used for all of the manufacturing process in the lifecycle of the product. The culture will need to progress from two-dimensional paper prints to smart three-dimensional models that are rich with data. These models will drive the process and be the final word for part acceptance; paper prints will not be needed nor produced. These types of models will drive almost all of the military’s new designs, and if the organization is not prepared for this change, it will lose many opportunities to remain competitive.
