The frontal working area of the electrode in an Electrochemical Machining (ECM) operation is 1000 mm. The applied current is 900 amps and the voltage is 12 volts. The resistivity of the electi olyte is 140 Q-mm. The material being cut has a valency of 4 and specific removal rate of 0.0342 mm /A-s. If the process efficiency is 90%, determine the material remova! rate (MRR) and inter-electrode gap after 30 minutes of machining when the resistivity of the electrolyte has dropped to 75% of its original value.

In the electrochemical machining of an iron surface with 10 mm×10 mm in cross-section, the NaCl in water is adopted as electrolyte. The gap between the tool and workpiece is 0.2 mm. The supply voltage is 12 V DC. The specific resistance of the electrolyte is 3Ωcm. (For iron, valency=2, atomic weight=55.85, and density=7860 kg/m3). Please estimate the material removal rate and the tool feedrate.
Manufacuring Processes An electro chemical machining (ECM) operation is employed too cut a square hole in a copper plate of 18 mm thickness. The dimensions of the hole is 20 mm on each side, however, the electrode dimension shall be slightly less than 20 mm to allow for overcut, and its shape includes a hole in its center to permit the flow of electrolyte and reduce the area of cut. The frontal area of electrode is 180 mm2. The specific removal rate for copper is C = 7.35 x 10-2 mm3/A-s. The applied current is 950 A. At 90 % efficiency, determine the time required to cut a hole of required dimensions.
