Based on analysis of structural characteristics of blisk

technical requirements and characteristics of the material

the technical scheme of electrochemical machining is determined. Three key technologies such as cathodic design and trajectory calculation

forming cathode design and parameter optimization techniques are analyzed. The key steps such as design of cathode face

design of flow field

calculation of trajectory and calculation of gap are mainly discussed in detail and further optimized by repeating experiments to solve problems of uneven flow field and sparking short circuit. Finally

the feasibility of the process is verified

and the leaf disc of the nested electrolysis is more uniform. It can meet the subsequent fine electrolytic processing requirements

and achieve good result.
