Nowadays, the electrochemical method is widely used in manufacturing parts, but some other methods are difficult or impossible to perform or perform with low productivity. The paper presents the calculation and experimentation of selecting the main parameters when designing and manufacturing the channel electrochemical cathode. Through calculations and experiments, the paper has determined the working length of the cathode in the range of 15 to 20 mm, the gap between the cathode and the inner surface of the cannon barrel 30 mm in the range of 0.8 to 0.9 mm. This result is used to design and fabricate the electrode cathode when electrochemical manufacturing groove of the naval 30 mm cannon barrel.
