Electrochemical machining operations are performed with tungsten as the tool, and copper and aluminum as two different workpiece materials. Properties of copper and aluminum are given in the table below.

Ignore overpotentials, and assume that current efficiency is 100% for both the workpiece materials. Under identical conditions, if the material removal rate (MRR) of copper is 100 mg/s, the MRR of aluminum will be _______ mg/s (round-off to two decimal places).
    Correct answer is '28.5'. Can you explain this answer?

    Given : Faraday’s constant (F ) = 96500
    Current efficiency =100%
    Material removal rate of Cu (MRRCu) = 100 mg/s
    = 100 x 10-3 g/s

    Material removal rate,

    For Cu,


    I = 306.34 Amp
    For Al,

    MRRAL = 0.0285 g/sec = 28.5 mg/s
    Hence, the correct answer is 28.5
