Abstract

Aircraft skin, skeleton, and wing components contain a large number of riveted holes. There are few hole-making studies of double lug anchor nut connection 2024 aluminum alloy (Al2024) plates. To improve the quality of riveting holes on the anchor nut, two different hole-making schemes for two different sizes of holes on connection plate of the double lug anchor nut were proposed, and orthogonal experiments were conducted. The holes distributed on both sides were drilled, and the range analysis results and the optimal parameters were obtained: the spindle speed is 3000 r/min, and the feed rate is 0.04 mm/r. The coaxle hole with middle hole of nut was machined by the helical milling plan, the analysis results and the optimal parameters were obtained: the spindle speed is 3000 r/min, the feed rate is 0.08 mm/r, and the number of blade teeth is 4. Based on the obtained optimal parameters, the process sequence of first drilling and then helical milling (D + H) and first helical milling and then drilling (H + D) was proposed. In drilling, there is a significant fluctuation of force in the y-axis direction when using the process sequence of D + H. At the beginning of the helical milling experiment, the rising speed of the axial force of D + H is smoother than H + D. The deformation along the x-axis direction and the along the y-axis direction of the process sequence of D + H is 63.9 μm and 49.6 μm, which are 75.5% and 76.5% of H + D. Finally, experimental studies were carried out in the workshop. In drilling, the burr height is 77.1 μm, and hole diameter is 2.617 mm. In helical milling, the burr height is 20.7 μm, and the hole diameter is 5.023 mm. The deformation of the Al2024 is 64.3 μm. The optimal machining parameters and the process sequence of D + H can meet the technical requirements of connecting plate of the double lug anchor nut.
