Electrolytic machining system and electrolytic machining method

An electrolytic machining system comprising:

• a controller;
• a drive member electrically coupled to the controller;
• a power supply module;
• a dividing circuit electrically coupled to the power supply module and configured to divide a total voltage taken from the power supply module into a plurality of independent working voltages;
• a detecting circuit electrically coupled to the dividing circuit and configured to detect each independent working voltage and feed back a result of detection to the controller;
• and
• an electrode module installed on the drive member and comprising:
• a printed circuit board electrically coupled to the detecting circuit, and
• an electrode assembly comprising a plurality of electrode tubes arranged in a matrix and electrically coupled to the printed circuit board,
• wherein each independent working voltage is supplied to an electrode tube via the printed circuit board during a movement of the electrode assembly with respect to a workpiece, and the controller controls the drive member to move the electrode assembly away from the workpiece when the result of detection of the detecting circuit indicates an incorrect working voltage.
