The Research of Ontology-based Digital Twin Machine Tool Modeling

As a core manufacturing resource, CNC machine tool acts a pivotal part in the new trend of smart manufacturing. Aiming at the intelligent demands of CNC machine tool, this paper proposes a digital twin modeling framework for CNC machine tool. Furthermore, a semantic model of CNC machine tool based on ontology is established to solve the issues of multi-source heterogeneous data fusion and insufficient semantic information, which contributes to condition monitoring service to fully perceive the running status of machine tool.
