stress relieving after finish machining?
(OP)
i know that stress relieving is done after rough machining in order to avoid distortion while hardening.(by the way i am using vacuum hardening for my tools.i want to know whether it will be helpful or not if stress relieving is done after finish machining in order to avoid distortion.(without rough machining and stress relieving before finish machining)






RE: stress relieving after finish machining?
Machinery’s Handbook, 25th Edn., p. 522 mentions stress relieving high-speed steel after sub-zero cooling treatment.
Stress relief in some cases improves corrosion resistance.

I think the vacuum process can be very useful for reducing HT distortion. That assumes the process can get cooling rates adequate for your application. Best to discuss specifics with possible suppliers and look for insights there. Reputation is everything when dealing with this type of work, IMO.
The size, material and geometry of the part and nature and sequence of machining operations all have great effect on HT distortion. More specifics will help forum members assist you. Good luck!
