[0003] At present, casting is a commonly used manufacturing method in the parts processing industry because of its low manufacturing cost, great process flexibility, and the ability to obtain complex shapes and large castings. Some parts are still processed using casting technology. However, due to the large number of processes and complex influencing factors in the casting method, most existing technologies rely on the experience of technicians to adjust the operating parameters of the equipment, and are unable to accurately analyze the impact of various factors on the quality of castings, resulting in poor accuracy in the regulation of casting process parameters and more casting defects. Moreover, manual inspection cannot detect equipment failures in a timely manner, resulting in defects in a large number of castings, which require recasting, wasting a lot of time, and low production efficiency.

Otherwise, the system continues to detect.

[0025] According to the above technical solution, in step S4, the detection data of the casting is obtained, compared with the database, the abnormal data is anchored, the corresponding casting defect type in the database is retrieved according to the abnormal data, and the mark in the casting defect type is identified. If it is a repairable mark, the visual image of the casting is identified, the gradual defect position is anchored, and the system performs grinding and cutting to obtain a casting that meets the conditions.
