Re: setting peening time with saturation curve... Jack Champaigne 03/11/24 04:09 PM
Explaining coverage separate from saturation time is the biggest challenge we have in our classrooms.
One thing that might help is to understand that the Almen strip is unique for determining the energy of the shot stream. It is NOT used for coverage time because it is not made of the same material that you are peening. Typically 100% (or could be 200%) coverage is requested. This means that 100% of the actual part has complete denting. This has nothing to do with the saturation curve and it T1 and T2 time.
Hope this helps.
