This　paper　takes　the　single-wall　wall　manufactured　by　wire　arc　additive　manufacturing　(WAAM)　as　the　research　object　and　compares　it　with　the　as-cast　aluminum　alloy　with　the　same　series.　By　using　feed　rate,　cutting　depth,　spindle　speed,　etc.,　as　single　or　compound　parameters,　the　machinability　of　the　sample　is　analyzed.　The　results　indicate　that　the　influence　of　varying　parameters　on　the　as-deposited　aluminum　alloy　follows　the　order　of　feed　rate　＞　cutting　depth　＞　spindle　speed.　As　the　feed　rate　increases,　the　surface　roughness　initially　decreases　and　then　increases,　with　the　optimal　surface　quality　achieved　at　12　mm/s　(with　a　surface　roughness　of　2.013　mu　m).　Different　from　the　as-deposited　alloy,　the　influence　of　the　parameters　on　the　as-cast　alloys　follows　the　order　of　spindle　speed　＞　cutting　depth　＞　feed　rate.　The　experiments　reveal　that,　for　both　as-deposited　and　as-cast　states,　the　trends　of　the　impact　of　cutting　depth　and　spindle　speed　on　surface　quality　are　consistent.　However,　at　low　feed　rates　(2-12　mm/s),　for　as-deposited　states,　the　surface　quality　of　as-deposited　samples　becomes　smoother　as　the　feed　rate　increases　(contrary　to　common　knowledge).　This　result　can　be　attributed　to　the　elevated　milling　temperature,　which　softens　the　material,　making　it　easier　to　remove　and　reducing　the　surface　roughness.
