Vibration analysis and experiments on electrochemical micro-machining using cathode vibration feed system

Abstract

Based on mechanics of vibration and electrochemical principle, an electrochemical micro-machining method using cathode vibration feed was proposed. The electrochemical micro-machining system using cathode vibration feed was designed and manufactured. The dynamics model of vibration excitation mechanism was given. The vibration modes and natural frequencies were discussed. The electrochemical micro-machining test using cathode vibration feed was completed. The test results were compared with electrochemical micro-machining test ones using DC and pulse power. The experimental results show that electrochemical micro-machining using cathode vibration feed can improve the accuracy of electrochemical micro-machining. Machining accuracy of the micro holes is close to one of the electrochemical micro-machining using high-frequency pulse power. The micro-machining technique is simple, without using high-frequency pulse power.
