(a) 0.01 to 0.1 mm

(b) 0.1 to 0.3 mm

(c) 0.3 to 0.5 mm

(d) 0.5 to 0.7 mm

I had been asked this question during an internship interview.

The doubt is from Electrochemical Deburring in section Electrochemical Processes of Advanced Machining

Answer 1

The correct option is (c) 0.3 to 0.5 mm

For explanation: The inter electrode gap maintained in ECDB process, range between 0.30 – 0.50 mm.
