Question

What is the value of surface roughness obtained in Electrochemical deburring process?

(a) 0.1 to 1 µm

(b) 1 to 2 µm

(c) 2 to 4 µm

(d) 5 to 8 µm

This question was posed to me in an interview for internship.

My question is from Electrochemical Deburring in division Electrochemical Processes of Advanced Machining

Answer 1

Correct option is (c) 2 to 4 µm

To elaborate: Surface roughness obtained in ECDB process is about 2 to 4 µm.
