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　mu　m　and　49.6　mu　m,　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　mu　m,　and　hole　diameter　is　2.617　mm.　In　helical　milling,　the　burr　height　is　20.7　mu　m,　and　the　hole　diameter　is　5.023　mm.　The　deformation　of　the　Al2024　is　64.3　mu　m.　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.
