In electro chemical machining of an iron surface that is 20 mm x 20 mm...
Given data
Cross sectional area of the gap , Agap = 20 x 20 = mm2
Gap between the tool and work piece , H = 0.2 mm
Voltage , V = 13 V
ρ = 2 Ωcm = 2 x 10 Ωmm
Material removal rate in ECM by considering 100% current efficiency, MRR = AI / ZF
= 72605 / 193080
= 0.376 g / s
