Not only are advances in automation pushing the boundaries of the end technology we put produce, but they are also revolutionizing the conception stages of technology. When engineers once used documents as the data source for a product, model-based engineering has come to take a prominent spot on the stage.
In the context of manufacturing, model data drives production and quality processes. A product model used in manufacturing is a container not only of the nominal geometry, but also of any additional information needed for production and support. This additional data, known as Product Manufacturing Information (PMI), may include geometric dimensions and tolerances (GD&T), material specifications, component lists, process specifications, and inspection requirements.
Two critical factors give MBE significant advantages over drawing-based or document-based engineering: 1) computer interpretability and 2) data associativity. The primary reason to use a data model in engineering and manufacturing is that a model can be processed directly by engineering software applications. In a document-based environment, humans must interpret the engineering documents and then enter the information into the specific user interface of each engineering application. Whether it is finite element analysis (FEA) or computer aided manufacturing (CAM), each application creates its own internal model. In the past, the only access to this model was through the application’s user interface (keyboard and screen). With MBE, the applications read and write the models directly. This results in fewer errors and a drastic reduction in processing time.
