Abstract

Abstract: In response to the intelligent and digital requirements for virtual debugging, performance evaluation, and machining quality optimization of CNC systems in the field of production and manufacturing, a five dimensional digital twin system of CNC systems combining virtual and real is constructed based on digital twin technology. And combined with relevant new generation information technology, the digital twin system is modeled in multiple fields, including information models, mechanism models, and digital threads, to achieve comprehensive simulation and analysis of physical entities and processing processes. The study also verifies the feasibility of data transmission between CNC systems and digital twin applications using the OPC UA data transmission architecture, ensuring the reliability and efficiency of information exchange during virtual machining processes in CNC systems. Specifically, based on this, a twin system for evaluating CNC machining performance and a twin application for optimizing CNC machining trajectory have been developed. By combining digital twin technology with CNC systems, virtual simulation of CNC machining processes, machining performance evaluation, and process optimization have been achieved, proving the rationality and applicability of the proposed digital twin system for CNC systems, thereby improving the intelligence and digitization level of CNC systems.
