Abstract

The invention relates to a data conversion and extraction method for model based definition (MBD). The method comprises the following steps: establishing an MBD design model on the basis of a unique data source provided by a design department; converting the MBD design model into an MBD process model; collaboratively establishing an MBD procedure model according to different demands of the MBD process model; establishing a process file template according to the demands of different departments, wherein the template contains keywords mapping process information attributes; acquiring data in the current MBD procedure model, exporting corresponding data structures according to the demands of different departments, and replacing the keywords in the process fie template to realize automatic conversion and extraction of MBD model information according to the demands of different departments. According to the method disclosed by the invention, the unique data source MBD model provided by the design department is taken as a basis, machining and manufacturing information is expressed by making full use of a three-dimensional measure, manual intervention of the consistence and integrity of process data is not required, automatic extraction of MBD model data according to different service demands can be realized, and paperless machining is realized.

Description

technical field [0001] The invention relates to an application field of MBD technology, in particular to a data conversion and extraction method based on model definition. Background technique [0002] In the field of industrial product manufacturing design, the previous process diagram design was drawn by two-dimensional CAD tools, and the process processing information was added in CAPP software. The processing data required support from different software platforms, which increased the cost of the enterprise and interrupted the data chain of manufacturing collaboration. , Repetitive work is labor-intensive, and the consistency and integrity of process data are guaranteed by humans, which is prone to errors and makes the audit process an efficiency bottleneck. [0003] MBD (Model Based Definition, model-based definition) is a full-information model based on three-dimensional model data to describe geometric shape information, product manufacturing information (dimensions, ...
