Importance of MBD, P&T  Documents....!

What is MBD ?

                    Model-based definition is an approach to creating 3D models so that they effectively contain all the data needed to define a product. With MBD, the model become the source authority that drives all engineering activities. This model may further be used downstream by suppliers and across organizations within an enterprise.

Why we used MBD ?

                            Past years, engineer used 2D drawings to deliver product manufacturing information—even as they designed models in 3D. Now, using model-based definition (MBD) methods, engineers embed product data directly in the 3D models, creating a single, reliable source of truth for the whole extended team that prevents errors and saves everybody time.

Why MBD is Important..?

                          MBD is important, because it increases the speed, accuracy, and efficiency of manufacturing complex parts while also reducing the cost of through automation and time-savings.

Some of the Importance of MBD..

1. MBD further automates manufacturing with software-readable product and manufacturing information (PMI).
2. MBD increases technical communication efficiencies.
3. MBD improves product quality.
4. MBD establishes manufacturing competitive advantages.
5. MBD unleashes the power of emerging technologies.

 Are benefits of MBD real ?

                        

                   The concept behind MBD is to consider 3D product model as the sole carrier of comprehensive information across all stages of the production, eliminating the need of 2D drawings. The MBD dataset fundamentally consists of a 3D solid model with all geometry features as well as 3D annotations of required tolerances and manufacturing instructions, to specify a complete product definition.

                   While adopting the concept of MBD does appear to be the next logical step towards achieving reduced time-to-market & improved product quality, the idea somehow looks quite naïve in present conditions, where manufacturers are still struggling to transform their operations digitally.  

Why isn't it working ?

                  One of the main reasons is that 2D drawings actually work quite well. The reason why we still use them is that they have remained effective in communicating the design intent clearly. A 3D PDF consisting of a model and engineering drawings serves the purpose efficiently, at least for the shop floor people where the actual manufacturing is meant to occur. As long as people are involved in the process, we are going to need drawings.
