Abstract
The invention provides a thin-wall part processing method which includes following steps: (1) selecting cutters required in different processing steps, arranging the cutters into a cutter disk successively and performing axial-fastening reference positioning to a to-be-processed part; (2) 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 200-230 m/min and 70-74 mm/min, and the linear speed and the cutting feed of fine processing are respectively 305-370 m/min and 100-115 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.
