[0002] In the production of aluminum alloy subway projects, some subway projects require a circular hole to be machined in the middle of the roof side beam, and the edges around the circular hole also need to be manually drilled and riveted for the installation of the lampshade. According to the drawing requirements, the distance between the machined circular hole and the four manually drilled holes is 1mm, the four manually drilled holes are in equal relative positions, and the diagonal center coincides with the center of the machined circular hole. Because the roof side beam is thin, the manual drilling accuracy is low and the deviation is large, the machined circular hole is easily damaged during manual drilling, and the relative dimensional accuracy of the four manual holes cannot be guaranteed, causing damage to the parent material and making it impossible to install the lampshade. Therefore, it becomes a major problem in production.
