Titanium alloy can be removed through its own combustion reaction under the conditions of electrical discharging and combustion-supporting oxygen. With the combustion-supporting oxygen pressure increasing, the erosion rate of the titanium alloy increases. But it will explode when the oxygen pressure increases to a certain extent. The material forming accuracy will reduce. A new processing concept is proposed based on the controllable melting and explosion mechanism for the efficient turning induced by electrical discharge machining (EDM). The concept can keep titanium alloy processing in the controllable melting and explosion condition to increase its corrosion removing rate through the induction system of quantitative high-pressure composite low-pressure, which is compared with the machining method that only passes into the low-pressure oxygen. The results show that the corrosion removing rate of controllable efficient processing of titanium explosion with intermittent quantitative high-pressure combustion oxygen, which is based on turning composite machining with controllable melting and explosion mechanism, is much higher than that of only spark-induced combustion turning machining with low-pressure oxygen.
