- Abstract
In view of the slender structural characteristics of titanium alloy wire coil as raw materials for aviation fasteners and the machining difficulties, a centerless lathe was used to finish the surfaces of titanium alloy wire coil. Considering the requirements of high precision surface quality after turning 9 in order to improve the machining stability of centerless lathe 9 a multi-degree-of--freedom coupled flutter vibration mechanics model was established considering process damping effect. By solving the model and drawing the stability lobe diagram of the cutter head cutting system of centerless lathe for stability analysis, the stable machinable parameter group was obained. Further analysis of the influences of tool structure parameters shows that when the radius of the tool nose is as 0.1 〜0.3 mm9 the rake angle of the tool is as and the clearance angle of the tool is as 2°~5°, the stable machinable parameter set with the highest design safety may be obtained. The experimental platform was set up to ver讦y the theoretical analysis results, and the obtained tool structure parameter selection domain and stable machinable parameter set may provide a reference for surface finishing of titanium alloy wire coils.
