The invention discloses a thin-wall cavity part machining method which comprises the following steps: blanking according to a design size to obtain a cuboid blank; the machining allowance of the cuboid blank is determined, and the workpiece thickness is milled according to the workpiece forming size; firstly, rough machining is conducted on the blank piece through three-axis equipment, in the machining process, a method of clamping and positioning the two sides of the blank piece is adopted, an inner cavity, a lug hole, a side hole and the boundary dimension are milled, and it is guaranteed that the machining precision is +/-0.1 mm; secondly, the rough machining part is subjected to finish machining, the rough machining step is repeated, a finish machining part is obtained, and it is guaranteed that the machining precision is +/-0.003 mm; clamping the finish machining part on a five-axis part by using a tool; and laser scanning is used for scanning and automatic centering of the finish machining part, and mac
