Three-dimensional technological procedure guiding type method and system based on structured knowledge

Abstract

The invention discloses a three-dimensional technological procedure guiding type method and system based on structured knowledge. The method comprises the following steps of: creating working procedures and working steps under a technological model structure tree; acquiring manufacturing resource information and inspection information of the working procedures or the working steps, and selecting typical geometric features with the similarity larger than a set threshold value from a model feature library; inserting the typical geometric features into the process model structure tree and performing attaching to the model geometry, determining the sizes of the typical geometric features, and completing model geometric feature construction; and based on the manufacturing resource information, the inspection information or the structured process knowledge base of the working procedures or the working steps, acquiring the process symbols of the model geometric features. According to the method, the enterprise-level structured process knowledge base reflecting the process design logic relation is established, automatic construction of the three-dimensional process procedure design process is achieved, and the process procedure design efficiency is improved.

Description

technical field [0001] The invention relates to a three-dimensional process procedure guidance method and system based on structured knowledge, and belongs to the technical field of three-dimensional digitalization of products. Background technique [0002] In order to meet the needs of enterprise product development and production, process design, as the core link between product design and manufacturing, needs to be coordinated with product design to output complete process information for manufacturing. The 3D process design uses the 3D model as the information carrier to realize the process design and transfer in the 3D environment. [0003] The traditional process design is carried out in the form of documents and tables, the expression of process information is incomplete, and the process intention is not obvious; the 3D process design process needs to output process documents within a certain period to guide production, but the process personnel construct the process ...

Problems solved by technology

At the same time, in terms of model annotation, the annotation symbols cannot be directly generated, and the symbol information needs to be selected one by one for the parameter information, which cannot be quickly and accurately generated and labeled, which directly increases the workload and difficulty of the process designer.
