After your machine is set to peen to the correct intensity, the only parameter you can change is the time it takes to peen the part.
Understand that the amount of time you peen the part does not affect intensity. The part peening time ONLY affects the coverage. With that in mind, you can change the peening time of the actual part. I want to re-visit a couple of your parameters from above.
5. Translation speed of nozzle. and 7. Rotary speed of part.
These will not affect intensity, as long as the nozzle distance and media impingement angle in relation to the part surface remains the same as it was in the positive intensity test/verifications.
Jack must have overlooked those two.
