Abstract
As a basic equipment for manufacturing,CNC machine tools are developing towards high speed,high pre-cision,high flexibility and high intelligence.For the intelligent needs of virtual commissioning,health management and performance evaluation of CNC machine tools in intelligent manufacturing,a digital twin implementation frame-work of CNC machine tools for intelligent applications was established,a digital twin multi-domain modeling process based on geometric,physical and data models was proposed,and the key enabling technologies in the construction of digital twin models was studied.A multi-layer hierarchical CNC machine tool digital twin function implementation framework was built to promote the implementation of digital twin intelligent applications of CNC machine tools.It also develops A digital twin CNC machine tool application system based on the industrial internet architecture was developed,a CNC machine tool twin model in virtual space was constructed using data information in physical space,and the performance evaluation,health management,virtual debugging and other intelligent application service mod-ules was established to realize intelligent applications of digital twin CNC machine tools and improve the intelligence level of CNC machine tools.
