【Abstract】 Forging bed is one of the most common equipment in the field of metallurgy,and its operation efficiency affects the quality of metallurgical forming. A fast in-place detection system was established for NC forging bed,which can realize the high efficiency discrimination of forging hammer image,and then the prediction simulation model was established based on the tool surface wear data. The results show that adding Dropout can improve the model learning performance and improve the network prediction performance. It can also complete the feature matching convergence process faster, and the optimized DBN model shows more stable and accurate prediction results.The research can be effectively applied in the actual machining process and has a good theoretical support value.更多还原
