This is the first of three papers on high rate Electrochemical Machining. Feed rate limiting mechanisms are discussed along with qualitative predictions. Methods of increasing feed rates are studied theoretically and experimentally. The use of high supply voltages (118 volts) high electrolyte pressures (330 bars (4800 psi)) and high flow velocities (192 M/sec) when machining iron in aqueous sodium chloride electrolyte led to feed rates of 10.8 cm/min (4.25 in/min). The following two papers will discuss a theoretical model of the ECM process and present high temperature and pressure electrolyte conductivity and ion mobility.
