Application of Key Technologies for Product Process Collaborative Design Based on MBD

The MBD (Model Based Definition) based collaborative design technology for product processes takes 3D model data as the core of information in the design and manufacturing process, and achieves close cooperation and communication between the design and manufacturing departments through collaborative design. This article introduces the key technologies in collaborative design of products and processes based on MBD, and provides a detailed introduction to three-dimensional model annotation technology, machining process design technology, welding assembly process design technology. Based on the three-dimensional model, the geometric form and related attributes of the product are fully embedded in the model, achieving digital expression and sharing of design data.
