Flow Field Optimization and Process Experimentation for Electrochemical Machining of Special-shaped Grooves on the Inner Surface of Thin-walled Cylinders
In order to solve the problems of uneven flow field,easy cathode short circuit and poor machining surface quality in electrochemical machining of irregular grooves inside thin-walled cylinders,two cathode supply methods including split flow and direct current were proposed,and geometric models and mathematical models of gap flow field for split flow and direct current cathodes were established.By simulating the gap flow field of the supply methods,the influence of supply methods on the uniformity of gap flow field was explored,and process experiments were carried out to verify it.The simulation result showed that the flow field is more uniform when using a split cathode than a direct current cathode for liquid supply processing.Under the optimal process parameters,cathode short circuits can be avoided and the surface quality of electrochemical machining of irregular grooves in thin-walled cylinders can be improved.
