1.	The cold working of material facilitates its cutting operation due to a decrease in its ductility.(a) True(b) FalseI 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» 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.
