Titanium alloy TB6 has been widely used in the field of aerospace because of its excellent properties. However, the fabricating of complex structure components from titanium alloy TB6 forging-casting fittings with large cutting allowance is inefficient and costly in cutting tool and machine tool to cause great waste. In order to solve this problem, one type of Electrochemical Machining (ECM) for rapidly removing large allowance by thin hollow cathode is proposed. The spare material is cut and separated from the blank, so as to improve machining efficiency and reduce the cost. In order to improve the flow field characteristics of ECM and machining accuracy, the vibration of electrode is applied, the model for ECM with vibration is built, and experimental research is carried out. The experimental results show that the conductivity of electrolyte in the whole area tends to be consistent with the appropriate vibration amplitude and frequency (A=0.05 mm, f=50 Hz), so that the machining accuracy, stability and efficiency can be improved. The applicability of electrochemical cutting with vibration by thin hollow cathode is proved by successful cutting of complex structure components.
