Abstract: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.
