Best answer
The correct choice is (a) True

For explanation I would say: Reducing the casting of residual stresses can improve the machinability of the casting and increases tool life also. On the other hand, the castings machined after reducing the residual stresses have good dimensional stability, persistent precision and good reliability of the casting products.
