Abstract: In response to the problems of low sample quality, low raw material utilization rate, and opaque management information in the steel bar processing process, this paper designed a digital steel bar processing management workflow. Through key technologies such as steel bar cutting BIM (Building Information Modeling) model generation, data sharding processing, and intelligent equipment control, the paper formed a beam yard steel bar processing management system with model management, bill of materials conversion, steel bar processing, equipment management, schedule management, and safety and quality management as the main body. The application shows that the system has increased the utilization rate of steel bars to over 97%, improved processing efficiency by over 50%, and assisted in the scientific allocation of steel bar raw materials.
