Abstract：With micro-stress support and cantilever double-side table setting to ensure stress-free de⁃formation of parts clamping as the core，and by optimizing the combination of tool trajectory and cutting parame⁃ters，the traditional clamping method can not guarantee the processing accuracy of U-shaped shell parts，and the processing accuracy is improved from IT8 to IT6.

Keywords：micro-stress assisted support；clamping stress-free deformation
