| Abstract: |
| Aimed at the machining deformation problem of the typical thin-walled parts in the spacecraft, based on the theory of metal cutting, an intensive study of precise machining technology of thin-walled parts is made through the process design strengthening rigidity, the clamp with less stress, less cutting force and so on. Moreover, the practices of precise machining also show that the rigidity of parts during machining can be enhanced by various process means, which make the deformation of machining parts less and ensure the machining precision of thin-walled parts more easily attained. |
| Key words: thin-walled parts precise machining strengthening rigidity less stress |
