A Review of Research of Digital Twin Technology for CNC Machine Tools

As manufacturing systems developed in the direction of digitization, networking and intelligence, digital twin technology has been developed so as to enhance communication between real machining and simulation. CNC machine tools equiped with digital twin technology can be seen as a kind of CNC machine tools in a virtual environment with digitalization and networking as the core, and is an important way to realize the intelligence and automation of CNC machine tools. The development of research on digital twin technology in CNC machining is reviewed in this paper, and the future development trend is prospected by combining the current research hotspots. The whole content can be divided into the following parts. First, the basic concept of digital twin CNC machine tools is introduced. Then, the related research at home and abroad is explained and analyzed from the aspects of error prediction, parameter optimization, real-time monitoring and troubleshooting, etc. Finally, the current problems are pointed out and future development trends and research directions are proposed, which provide some references to promote the realm of future manufacturing and also play a pivotal role in the exploration and implementation of digital twin technology.
