1.	For a better surface finish, which type of current distribution is required?(a) Even(b) Uneven(c) Even & Uneven(d) None of the mentionedThis question was posed to me at a job interview.I need to ask this question from ECM-Process Characteristics topic in division Electrochemical Processes of Advanced Machining
Answer» Correct answer is (a) EVEN Explanation: More even distribution of the CURRENT density LEADS to a better surface FINISH.
