Abstract

The invention discloses a three-dimensional MBD process model organization and expression method based on a view. Therefore, under the background of collaborative three-dimensional manufacturing, a unified data source for product design and manufacturing is achieved, a visual three-dimensional visual process design environment is provided, a three-dimensional MBD process model of a product is scientifically managed, and various process information needed by product machining and manufacturing is clearly expressed.

Description

technical field [0001] The invention belongs to the field of three-dimensional digital process design, and relates to an organization and storage method of a product three-dimensional MBD (Mode-Based Definition, model-based definition) process model, and a method for expressing process information on the corresponding process model. Especially in the context of collaborative manufacturing, this method can be used to scientifically manage the product's 3D MBD process model and clearly express the process information contained in each process model, providing an intuitive 3D visual process design environment, and the process model generated at the same time can be It is directly used for NC programming in the subsequent integration environment. Background technique [0002] After years of promotion and application, 3D CAD technology has been widely used in machinery manufacturing and other industries. In order to more intuitively express product design and manufacturing infor...
