In order to address the low efficiency in traditional machine tools due to manual loading and unloading and repetitive commissioning issues faced during the setup of automated production lines,the digital twin design and simulation on the machine tool loading and unloading system are investigated and a virtual commissioning solution is proposed to complete the overall design of the machine loading and unloading system as well as to achieve control simulation of the system.The Process Simulate platform is used to build a 3D digital twin model of the machine tool loading and unloading system in a virtual environment.Through the PLC control system,the system layout,workflow,control logic and the robot loading and unloading path are continuously optimized by virtual commissioning to improve the machine tool loading and unloading system and enable offline programming of robots.The results show that the overall efficiency of the machine tool loading and unloading system is improved by 15%compared to the traditional manual loading and unloading by analyzing the control simulation of the system.Furthermore,research on the digital twin design and simulation has good applicability and can reduce the time of repeated commissioning and lower commissioning costs.
