Research of on-line non-contact geometry measurement system for large forging partsLIU Yong, HUANG Jie, LI Yang-yang, ZHENG Lu-yao, YANG Fu School of Manufacturing Science and Engineering, Sichuan University, Chengdu 610065, ChinaAbstract:In our country, the measurement technology of forging parts in most of forging plants is poorly developed, its measurement environments are harmful, and the artificial measurements cause great errors. When these are taken into consideration, an on-line non-contact geometry measurement scheme was proposed with the digital image process technology according to the principle of size measurement based on the CCD(Charge Coupled Devices). The software system was written by senior language, at the same time the calculation of the error produced in this scheme was analyzed. The experimental results showed that this system was cheap, its operation was easy, it had wide adaptability, and the measurement results could fulfill the actual requirements.[著者文摘]
