Abstract：Blades can be shaped by precise electrochemical machining with short production cycle and low production
costs. A series of experiments using this machining method is performed on GH4169G alloy blades. The results indicated
that the characteristics of flow field between electrode and cathode are significantly improved. Electrode passivation
is reduced and high surface machining quality is obtained. The optimum parameters are voltage of 15V, electrode vibrating
frequency of 25Hz, opening angle of 150°-195°, pulse frequency of 3000Hz. Blades produced with profile tolerance of
-0.012 - +0.013mm and roughness of Ra 0.51μm meet the machining requirements.
