In an electrochemical machining operation, the frontal working area of the electrode is 2.5 in2 . The applied current = 1500 amps, and the voltage = 12 volts. The material being cut is pure aluminum, whose specific removal rate C is 0.000126 in3 /A-min. (a) If the ECM process is 90 percent efficient, determine the rate of metal removal in in3 /hr. (b) If the resistivity of the
