Stress Relieving of 12L14 Material 1

[Butch1946]

Would you Add a Stress Relieve operation during the machining process to remove residual stress in the material prior to final machining?

If you are making parts from 12L14, then it's probably safe to assume that your primary consideration is machining cost and/or cycle time, and not mechanical properties of the material. So the additional cost and time required for a stress relief operation before final machining would seem unacceptable for this particular application. Free machining alloys like 12L14 require less energy to machine, and as a result they naturally tend to accumulate less strain during machining operations.
