Aiming at machining TC4 Titanium alloy blade of jet, reasonable cutter material, geometric angle of tool, machining quantity and the relative blunt standard of tool on condition that cutting parameters of rough and finishing machining are gained by means of a great many of cutting tests which are done by production department. And effect of geometric angle of tool and cutting parameters on tool life and varying laws of roughness of surface with changes of machining time are examined by means of cutting tests on condition that cutting parameters of rough and finishing machining. The experimental conclusions have a guiding significance and reference value to machine TC4 Titanium alloy blades with cemented carbide ball-end mill.
