If the electro chemical machining (ECM) is to be used to cut pure iron...
To estimate the current required for electrochemical machining (ECM) to cut pure iron with a material removal rate (MRR) of 800 mm3/min, we need to use Faraday's law of electrolysis.
Faraday's law of electrolysis states that the amount of substance produced or consumed at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte.
The equation for Faraday's law is:
M = (I * t * M) / (z * F)
Where:
M = mass of substance produced or consumed (in grams)
I = current (in Amperes)
t = time (in seconds)
M = atomic mass of the substance (in grams/mol)
z = number of electrons involved in the reaction (in moles)
F = Faraday's constant (approximately 96,485 C/mol)
In this case, we want to find the current (I), and the rest of the values are given.
Given:
MRR = 800 mm3/min = 800 mm3/min * (1 cm3 / 1000 mm3) * (1 mL / 1 cm3) * (1 g / 1 mL) = 0.8 g/min
M = 0.8 g
t = 1 min = 60 s
M = 56 g/mol (atomic mass of iron)
z = 2 (since Fe2+ ions are produced in the ECM process)
F = 96,485 C/mol
Substituting these values into the equation, we can solve for I:
0.8 = (I * 60 * 56) / (2 * 96,485)
Rearranging the equation to solve for I:
I = (0.8 * 2 * 96,485) / (60 * 56)
Calculating this expression gives:
I ≈ 129.35 A
Therefore, the estimated current required for electrochemical machining (ECM) to cut pure iron with an MRR of 800 mm3/min is approximately 129.35 Amperes.
