# In ECM process, the metal removal rate(M.R.R) is given by Where, F = Faraday constant I = Current amperes At = Atomic weight of material in gm V = Valance of metal dissolved A = Machined area in cm2 ρ = Density of work piece in gm/cm2

1.  M.R.R. = F*At/ρAV

2.  M.R.R. = F*ρ*A*V/I*At

3.  M.R.R. = I*AT/ F*ρ*A*V

4.  M.R.R. = F*I*At/ρAV

4

M.R.R. = F*ρ*A*V/I*At
