Abstract:: The structure of therobot special-shaped rotary bases is complex and difficult to process, which is the technical difficulty of the industry. Based on the analysis of the structure and technical requirements of the robot rotary base shell, the key munufacturing diffculties of the shell were extracted by taking the reference of the performance index of the horizontal machining center. A reasonable and effective CNC(computer numerical control) processing technology scheme of the robot special-shaped rotary bases was proposed, its special clamping devices and non-standard cutter were designed, and parallel tolerance and clamping force which affect processing accuracy were calculated. The test of the accuracy of the robot transposition shell processed by the processing scheme proves that the scheme and the designed clamping devices can meet the manufacturing requirements of this kind of special-shaped parts.
