The present invention provides a method for machining a flange face of an aluminum alloy hub, comprising the steps of: (I) pre-machining a hub flange; (II) machining two times with a 120° R3 boring tool with a total machining amount of 2 mm, and then reserving a machining allowance of 2.4 mm on the flange face blankafter processing; (III) machining two times with the 120° R3 boring tool with a total machining amount of 2 mm, and then reserving a machining allowance of 0.4 mm on the flange face blank after processing; (IV) machining with a 95° R0.8 hook tool, and then reserving a machining allowance of 0.05 mm on the flange face after processing; and (V) machining with the 95° R0.8 hook tool, then machining the remaining flange allowance, thus completing the machining. The advantages of the method are that: (1) the feed rate and turning amount of last finish turning of the flange face are reduced, and the planenessacceptability of the flange is ensured. (2) The machining direction is from the inner side of the flange to the outer side, and the tool bar is stressed during turning, so that the machining route is not easyto be deformed, and the guarantee ability is strong.
