Study on Superposed Magnetic Field ECM of Square Hole
To improve the Electrochemical Machining accuracy and little stray corrosion of shaping hole, one scheme is adopted to carry on the technical experiment, which inserted the permanent-magnet into the core of cathode in the square hole separately. Compared with the experiment of Electrochemical Machining without magnetic field, the magnet around the core of cathode inlaid with the magnet is in favor of improving machining accuracy under the same processing parameter, and helpful to reduce the stray corrosion.
