Abstract:

According to the basic principle of electrochemical machining , discussed in this paper are two kinds of cathode design methods , which were respectively based on the mathematical model of a simplified electric field and the mathematical model of actual electric field distribution in the machining gap. The effects of these two cathode design methöds on the distribution of electric field density in the gap were then compared and analyzed. Moreover ,a group of experiments was carried out to verify the design accuracy. The results demonstrate that the cathode de-sign method based on the actual electric field distribution in the gap accords better with the electrochemical machi-ning process and the corresponding cathode is more precise and reasonable.
