Abstract
The invention discloses a toric mirror surface shape measurement method. The measurement method is as follows: first, according to the parameter information of the toric mirror to be measured, using three-dimensional modeling software, establish a CAD model of the toric mirror to be measured and then import the CAD model into the three-coordinate machine software, based on the three-coordinate machine to measure and construct the geometric characteristics of the solid toric mirror, establish the workpiece coordinate system, which is consistent with the CAD model coordinate system. Finally, use the three-coordinate machine to perform scanning measurements to the solid toric mirror and compare the scanning result with the theoretical value to obtain the measurement result data. The measurement method of the present invention is based on the three-coordinate measurement technology and has the advantages of strong operability and high measurement accuracy.
