To solve this problem it is necessary to take into account the concepts related to electrochemical Machining Processes and metal removal. Metal removal rate is determined by Faraday's First law, which states that the amount of chemical change Produced by an electric current is proportional to the quantity of electricity passed, i.e,
Where,
V = Volume of material removed
C = Constant called the specific removal rate that depends on atomic weight (I attached a table with this values)
I = Current
t = time
Since we also have to consider the efficiency of the system to remove the Volume, of all the volume removed, only 95% will be efficient.
From our values we have to
Calculating the value we have that,
The area is simply the calculation of the total units by that of each piece, that is
Therefore we can calculate now the plating thickness through the ratio between Volume and Area
Therefore the average plating thickness on the parts is 0.000716in
