Calculate the material removal rate and electrode feed rate in the electrochemical machining of an
iron surface that is 25 mm × 25 mm in cross-section, using NaCl in water as electrolyte. The gap
between the tool and the work-piece is 0.25 mm. The supply voltage is 12 volt D.C. The specific
resistance of electrolyte is 3 2 cm. Take for iron:
Valency = 2, Atomic weight = 55.85,Density = 7860 kg/m³.
2. In the electrochemical machining of an iron surface with 20 mm× 20 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
15 V DC. The specific resistance of the electrolyte is 2 Q cm. (For iron, valency=2, atomic weight=55.85,
and density=7860 kg/m³).
Please estimate the material removal rate and the tool feedrate.
Give some advantages and disadvantages of the Surgical precision tool when it is made by the Carbon-based nanomaterials.
