Hi everybody,

I have a question about coverage and overpeening.

I know, overpeening is not allowed during production. It will reduce fatigue life.

Could everyone tell me the definition of overpeening, a very high intensity than requirements, or a very high coverage such as a wave on peened surface, or both?

our process specification is AMS-S-13165/AMS-2430, but I cannot find any description of overpeening.

Any advices?
