    Digital Twin Control Method of Machine Tool Feed Rate Based on Fuzzy Neural Network by YIN Jia, BAI Lele, TIAN Hui, WU Shijie, Hou Guijin, TANG Yuyang, LIU Hongguang, ZHANG Jun

    Published 2025-02-01
    “…The role of the digital twin in the cutting process is to connect machine tools with the developed digital monitoring system so that the machine tools can realize condition monitoring and adaptive optimization in the process of complex parts machining, and improve the machining accuracy and efficiency of parts. In the current milling process of aviation parts, considering many factors such as deformation, roughness, and tool wear, process engineers always set conservative parameters based on experience, resulting in low machining efficiency, and an inability to adaptively adjust the cutting parameters according to the cutting trajectory and machine load. …”
