Double-sided Electrolyte Supply Convection Flow Field Design and Experiment on Electrochemical Machining for Leading and Trailing Edges of Blades
For electrochemical machining of leading and trailing edges of blades,the article proposed a double-sided electrolyte supply convection flow field and conducted a comparative simulation of the flow field between the double-sided electrolyte supply convection flow field and the traditional single-sided electrolyte supply normal impingement flow field,and electrochemical machining experiments were carried out by using designed thin plate specimens.The simulation result showed that the designed double-sided electrolyte supply convection flow field got a more uniform distribution of flow field in the machining gap than traditional single-sided one.The experiment result showed that the contour of the thin section specimens processed by single-sided electrolyte supply normal impingement flow field had a head deviation defect,which was solved by double-sided electrolyte supply convection flow field with with an accuracy of-0.034 mm～0.044 mm and a surface roughness of Ra0.367 μm,all of which were better than those of single-sided electrolyte supply normal impingement flow field.
