Ontology-based model generation to support customizable KBE frameworks

摘要

In this paper, we propose a method for generating 3D geometry in CAD tools in a platform-independent manner through the use of ontologies. The aim is to enable knowledge-based engineering (KBE) systems to be developed with the freedom to incorporate development tools regardless of discipline or platform. Such functionality may then be utilized by small and medium-sized enterprises (SME) to cost-effectively manifest holistic development characteristics within a customized framework. An ontology structure is developed for storing knowledge about geometric shapes and functions that are commonly used for CAD software. A translation module and parser is then used to extract relevant information to generate 3D models in Siemens NX through Knowledge Fusion. Finally, an example is presented by generating a hand pump through a developed system.
