Question

Mechanical abrasion counts to how much amount of the material removal in ECG?

(a) 1 to 5%

(b) 5 to 10%

(c) 10 to 15%

(d) 15 to 20%

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

I'd like to ask this question from ECG-Material Removal Rate in section Hybrid Electrochemical Processes of Advanced Machining

Answer 1

Correct option is (b) 5 to 10%

The best I can explain: Material removal through abrasion counts to 5 to 10% of the total material removed.
