The titanium alloy thin-walled frame structure exhibited weak rigidity,high machining accuracy,and it was prone to milling deformation and clamping deformation during the machining process,so the requirements for the machining process were extremely high.In order to improve the processing quality of thin-walled brushed titanium frame,control the milling deformation and clamping deformation produced in the machining process,through analyzing the influence of the three elements of cutting,tool path,workpiece structure,process system rigidity and residual stress on milling deforma-tion,and analyzing the impact of process equipment on clamping deformation,the measures to control milling deformation and clamping deformation were proposed such as optimizing the process content and tool path,increasing the rigidity of workpiece and process system,and reducing the residual stress of workpiece,which were applied in the machining od thin walled brushed titanium frame.The machining results showed that the milling deformation of thin-walled brushed titanium frame could be reduced and the machining quality could be improved through the control measures.
