According to electrochemical machining gap balance theory,the physical and mathematical models were built.Based on FLUENT software,flow field distribution regularity in the gap of NC electrochemical mechanical composite cutting was obtained.According to the distribution regularity,the composite cathode was optimization designed,and the flow field distribution was improved.Taking a certain type of composite cathode for an example,tests were done to study on processing parameters of spindle speed,voltage,and electrolyte temperature on the influence of gap formation,and the equilibrium corresponding fastest feed rate was found.The results provide a basis for the actual processing application.
