[0062] Prepare the TC4 titanium alloy blisk as follows:
[0063] (1) Clamp the prepared forged TC4 titanium alloy disk hub 1 on the processing table of the CNC electrolytic machining machine tool, the cathode tool and the axis of the disk hub 1 form a certain angle on the vertical plane, and after positioning to the processing origin, pass the electrolyte , the cathode tool starts radial feeding to process a groove 3, the depth of the groove 3 is 3 mm, the depth of the groove 3 is 2% of the length of the final blade 2, and the length and width are consistent with the blade body 4 processed later. After one unit operation is completed, it is repeated sequentially along the circumferential direction until all the grooves 3 with the same design number as the blisk blades 2 are finally processed to obtain the preliminarily processed hub 1 .
[0064] The electrolytic machining parameters of groove 3 are: the electrolyte is 15wt.% NaCl solution, the electrolyte temperature is 35°C, ...

[0075] Prepare the Ti60 titanium alloy blisk as follows:
[0076] (1) Clamp the prepared forged Ti60 titanium alloy disk hub 1 on the processing table of the CNC electrolytic machining machine tool, the cathode tool and the axis of the disk hub 1 form a certain angle on the vertical plane, after positioning to the processing origin, pass the electrolyte , the cathode tool starts radial feeding to process a groove 3, the depth of the groove 3 is 3mm, the depth of the groove 3 is 3% of the length of the final blade 2, and the length and width are consistent with the blade body 4 processed later. After one unit operation is completed, it is repeated sequentially along the circumferential direction until all the grooves 3 with the same design number as the blisk blades 2 are finally processed to obtain the preliminarily processed hub 1 .
[0077] The electrolytic machining parameters of groove 3 are:
[0078] The electrolyte is 10wt.% NaCl solution, the temperature of the electro...
