In view of the problems of the current CNC spinning technology,such as low automation,low intelligence level and scattered and single yarn spinning process,a combination of digital twinning technology and CNC spinning technology was proposed.Yarn and spinning process was virtual simulated,the data of simulated model was fused and CNC spinning integrated control system was developed,the time sequential yarn structure parameters of the data fusion model,time sequential data fusion model of spinning processing parameters and data fusion model of sensor detection system output parameters were proposed.The flexible and intelligent spinning,visual monitoring of spinning system,far and near range control and data transmission of spinning process are realized based on data drive.The results show that digital twinning technology plays an important role in promoting the digitization and intellectualization of spinning process.
