Abstract

The invention provides a thin-wall part processing method which includes following steps: (1) according to a to-be-processed thin-wall part, selecting a three-blade taper-shank crude-processing milling cutter and a fine-processing milling cutter, wherein the roughness at a grinding part on a cutting edge of the fine-processing milling cutter is not less than Ra 0.3; (2) setting groove depth, groove width, the number of rough machining layers being 4-7, the thickness of a rough machining layer being 1-1.5 mm and fine processing allowance being 0.2-0.4 mm of the part on a numerically-controlled machine tool; and (3) setting the linear speed of rotation and cutting feed of a main shaft of a numerically-controlled machine tool, wherein the linear speed and the cutting feed of crude processing are respectively 220-230 m/min and 72-74 mm/min, and the linear speed and the cutting feed of fine processing are respectively 310-350 m/min and 105-110 mm/min. By means of the thin-wall part processing method, deformation of a thin-wall part due to direct clamping on a thin-wall pedestal for processing through a soft gripper or a jaw vice during milling is eliminated. The method simplifies the processing step of the part and allows paired processing.
