Simulation Analysis of Flow Field in the Electrolytic Machining of Deep Hole Slot Structure of Aero-Eengine Parts
In order to improve the machining accuracy and stability of the deep hole slot structures of aero-engine parts,the paper presents a machining cathode with an offset structure which is designed based on the characteristics of the deep hole slot structure and the positive flow mode of the electrolyte.The influence of the buffer plate of the machining cathode and the arrangement of the outlet holes on the distribution of the flow field is analyzed by the methods of theoretical analysis and simulation.The simulation results show that the addition of a buffer plate with outlet holes to the processing cathode can improve the stability of flow field and the uniformity of flow velocity distribution,satisfying the requirements of processing stability and processing accuracy.This study can provide a reference for high-precision electrolytic machining of deep hole slot structures.
