1.	With an increase in unmanned machining hours, what happens to the efficiency of ECM?(a) Increases(b) Reduces(c) Decreases(d) Increase and then decreaseI had been asked this question during an interview.I need to ask this question from ECM-Process Control topic in division Electrochemical Processes of Advanced Machining
Answer» The correct answer is (a) Increases The best I can explain: INCREASE in UNMANNED machining HOURS lead to a RAISE in efficiency of ECM.
