Three-Dimensional Model for Manufacturing and Inspection

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 The use of two-dimensional prints will be outdated, and a culture change will be needed to embrace this change.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 22 THE JOURNAL OF THE CMSC/SPRING 2013 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 resou
