online measuRing method of radial section line for Ring Forgings
The International Journal of Advanced Manufacturing Technology, 2019Co-Authors: Yu-cun Zhang, Xian-bin Fu, Shu Miao, Qun LiAbstract:Ring Forgings are widely used in industrial fields such as trains, construction machinery, beaRings, ships, petrochemicals, power generation, aerospace, and nuclear industries. In the dynamic manufactuRing process of Forgings, the online measurement of radial section line and various dimensional data plays a crucial role in controlling the dimensional accuracy and reducing the reject rate. Therefore, an online measurement method of radial section line for Ring Forgings based on line laser scanning is proposed. First, a laser scanning measurement system is established for this method. The laser scanning data of the radial uppermost layer section is obtained through this system. Second, all the point cloud data is described as a topological space. The double inverse limit space of the original two-dimensional point cloud information space is established. The topological transitivity between these two spaces is studied. Third, according to the study of the topological transitivity, the relationship of the coordinate position between each point is obtained. Then, a complete radial section line of Ring Forgings is formed. Finally, the radial dimension data of Ring Forgings is obtained. Two groups of dimensional measurement experiments have been done. One of the experimental objects is standard Ring Forging, the other of the experimental objects is non-standard Ring Forging. The result of the experiment shows that all errors satisfy the requirement of measurement precision.
