Research has been done theoretically and experimentally about Characteristics of Current density distribution over-work-piece in electro chemical machining which are related to machining accuracy.
Relations between characteristics of current density distribution and characters of electrolyte, which are electric conductivity and apparent electric conductivity which is varied with concentration of hydrogen gas, pressure gradient and flow rate, have been obtained by theoretical analysis.
Experimental study has been done and the experimental results are found to be qualitatively coincident with the theoretical results, but experimental valves are higher than theoretical valves.
