Question

The cold working of material facilitates its cutting operation due to a decrease in its ductility.

(a) True

(b) False

I got this question by my college professor while I was bunking the class.

Question is from Advantage and Disadvantage of Hot and Cold Forming in division Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

The correct choice is (a) True

The best I can explain: In the cold working of material, the material is deformed plastically which increases the strain hardening. This further increases its strength by losing its ductility; the loss of ductility is useful in machining operation. The breaking of chips becomes much easier due to less ductility, which further facilitates the cutting operation of material.
