A method for constructing knowledge components of multi-dimensional tooling design

Abstract

The invention relates to a method for constructing multi-dimensional tooling design knowledge components, belonging to the fields of knowledge engineering and digital design. This method constructs multi-dimensional tooling knowledge components from the perspective of process dimension and object dimension of tooling design process, and realizes effective organization, management and use of tooling design process knowledge. It mainly includes relevant design resources in the field of tooling design such as design rule knowledge, parametric and 3D models. According to different types of knowledge, a structured method is adopted to organize the rules, clarify the application of knowledge in knowledge components and the operation mode of completing specific design tasks. The invention realizes the automatic reasoning process of decision-making, and reduces the human intervention in the tooling design process. During the operation of the knowledge component, the parameter value input by the designer directly determines the operation result of the knowledge component, realizes the process integration from the user input requirement to the output result, and reduces the human-computer interaction part when performing tasks inside the knowledge component.

Description

technical field [0001] The invention relates to a method for constructing multi-dimensional tooling design knowledge components, belonging to the fields of knowledge engineering and digital design. Background technique [0002] Due to the complex structure and function of tooling, tooling-related design knowledge has rich semantic connotations and complex and diverse constraint relationships. The concepts and relationships in the field of tooling design are complex and ambiguous. In order to realize the unique definition of tooling design domain knowledge in the whole tooling design process, in the current technology related to knowledge components, some knowledge ontologies established by Dong Mingming in "Research on the Construction Method of Knowledge Components Supporting Design Reuse" are relatively fragmented and have not been established. A set of procedural, systematic and automated system does not form a general, multi-dimensional knowledge organization method, can...

In order to realize the unique definition of tooling design domain knowledge in the whole tooling design process, in the current technology related to knowledge components, some knowledge ontologies established by Dong Mingming in "Research on the Construction Method of Knowledge Components Supporting Design Reuse" are relatively fragmented and have not been established. A set of procedural, systematic and automated system does not form a general, multi-dimensional knowledge organization method, cannot well integrate various knowledge forms in the process of tooling design, and cannot effectively realize tooling planning and design, structural design, etc. Knowledge reuse in the entire design process; Gao Bo did not well organize and express the tooling design subject (workpiece), design requirements (tooling body and examples) and tooling design process in the "Research on Rapid Design of Tooling Components Based on Knowledge Components" The knowledge needed; Liu, Rosen, and Yu gave an ontology-based knowledge modeling method in "Ontology based knowledge modeling and reuse approach inproduct redesign", which divides variant design activities into parametric variant design activities and structural variants Design activities, corresponding knowledge will be provided when performing different activities, but the detailed solution steps of the method and the method of constructing the ontology are not given; In "Research on Tooling Intelligent Design Technology", a tooling component knowledge component modeling method was proposed, and the knowledge component model was defined, but the structure of the knowledge component was not refined, and the expression of design knowledge was formulated in depth, considering how to integrate Knowledge is well organized and managed, and detailed actions for internal execution are not specified
