What are the surface roughness values obtained while we use ECH process?
(a) 0.1 to 0.2 µm
(b) 0.2 to 0.8 µm
(c) 0.8 to 1.6 µm
(d) 1.6 to 3.2 µm
The question was asked by my school teacher while I was bunking the class.
My question comes from ECH-Process Characteristics, Applications topic in section Hybrid Electrochemical Processes of Advanced Machining
