Abstract: The flanging height of the stamped outer panel of the door cover directly affects the surface quality and dimensional accuracy of the door cover assembly after the flanging. In actual production, the flanging height must be accurately measured to ensure product quality. In production, the flanging height must be accurately measured to ensure product quality. This paper summarizes the problems existing in the three methods of measuring and calculating flanging height, which are manual measurement, trimming measurement and distance measurement, a new mathematical calculation method is established. The method is realized by using ATOS Scanbox optical measuring equipment, and the accurate measuring and calculating results of flanging height are obtained. At the same time, through the secondary development of ATOS measurement software, the calculation process of the method is automated. The new flanging height calculation method not only realizes the accurate measurement of flanging height, but also saves 200 h of manual labor in the new vehicle type project, and improves the efficiency of quality optimization.
