where,
A = gram atomic weight of the metallic ions
I = current (amperes)
p = density of the anode (gm/cm3)
Z = valency of the cation
F = Faraday (= 96,500 coulombs)
A = gram atomic weight of the metallic ions
I = current (amperes)
p = density of the anode (gm/cm3)
Z = valency of the cation

Which one of the following process conditions leads .to higher MRR\n E...
Higher current, larger atomic weight leads to higher MRR in ECM process.
Explanation:
Electrochemical Machining (ECM) is a non-traditional machining process that uses the principle of electrolysis to remove material from a workpiece. In ECM, a potential difference is applied between the tool (cathode) and the workpiece (anode) immersed in an electrolyte solution. The electrolyte acts as a conductive medium through which metal ions are transported away from the workpiece, resulting in material removal.
Higher Current:
- When the current is increased in the ECM process, it leads to a higher rate of material removal.
- A higher current results in an increased flow of metal ions from the workpiece to the electrolyte, causing faster dissolution and material removal.
- Therefore, higher current conditions contribute to higher Material Removal Rate (MRR) in ECM.
Larger Atomic Weight:
- The atomic weight of a material refers to the average mass of atoms in a particular element.
- In ECM, materials with larger atomic weights tend to have higher MRR.
- This is because materials with larger atomic weights have more metal ions available for dissolution in the electrolyte.
- As a result, a higher MRR can be achieved when machining materials with larger atomic weights.
Comparison of Options:
a) Higher current, larger atomic weight: This option satisfies both conditions that lead to higher MRR in ECM. Higher current increases the rate of material removal, and larger atomic weight provides more metal ions for dissolution.
b) Higher valency, lower current: Higher valency alone does not directly result in higher MRR. Lower current will reduce the rate of material removal.
c) Lower atomic weight, lower valency: Lower atomic weight reduces the availability of metal ions for dissolution, resulting in lower MRR. Lower valency alone does not directly result in higher MRR.
d) Higher valency, lower atomic weight: Higher valency alone does not directly result in higher MRR. Lower atomic weight reduces the availability of metal ions for dissolution.
Therefore, option 'A' - higher current, larger atomic weight - leads to higher MRR in ECM process.
