Research on alignment between processing and testing coordinates in flat mirror manufactory

To accomplish the alignment between processing and testing coordinates in the manufacturing of SiC flat mirror, which can be used to assure the acquisition of final surface, we established a kind of model based on least square method. With actual project, we achieved the alignment of two coordinates in the manufacturing of a φ800mm flat mirror. The surface reached the final accuracy with this alignment model, which verified the accuracy and reliability of this alignment model.
