Background
At present, the following two machining modes generally exist in numerical control machining of an aerospace structural part:
(1) the part is processed by suspending a milling molded surface, making edge strip holes and slotting on a vertical machine tool;
(2) and processing the second surface through the edge-drawing original point of the first surface.
