The invention belongs to the field of aircraft blank design and part machining, and discloses a method for machining a die-forging blank shared by U-shaped parts similar in structure. According to themethod, the U-shaped parts similar in material, size, technical requirement and type are found in the similar U-shaped parts, and a U-shaped part blank structure comprises a left containing area, a right containing area, a connecting area, a lower web and a notch which correspond to a left containing area, a right containing area, a connecting area, a lower web and a notch of each U-shaped part respectively. Under the condition that the connecting areas, the lower webs and the notches are identical in size, when the sizes and positions in the left and right containing areas of different U-shaped parts are close and only horizontal deviation happens, the blank is shared; the machining allowance of the blank is determined for unified design and manufacturing of the blank, investment of a newly manufactured die is r
