Question

The process of electromagnetic forming does not require any kind of lubrication.

(a) True

(b) False

This question was posed to me in homework.

I would like to ask this question from Electromagnetic Forming in chapter Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

Correct option is (a) True

To elaborate: In most of the forming processes, tool contacts with the specimen to get the desired output. But in the case of electromagnetic forming, the magnetic field is used to apply the pressure on the surface of a metal, which normally does not require any kind of lubrication. And it leaves no any tool marks on the metal surface.
