Question

Better accuracy and surface finish is achieved by performing hot forming process instead of the cold forming process.

(a) True

(b) False

The question was asked in exam.

My question is based upon Behaviour in Metal Forming topic in chapter Forming Process of Casting-Forming-Welding II

Answer 1

The correct choice is (b) False

To elaborate: Cold forming is a metal forming process that is performed at room temperature or slightly above. It has many advantages like better surface finish, high accuracy, high strength etc. And by performing hot forming operation, the surface finish of the part is very poor, which requires heavy machining to finish the metal part.
