Hi JZ,
This old rollover problem seems to be a never ending one.
In my experience the people machining parts to be shot peened rarely know what "Break Edge Condition" is needed to prevent unwanted rollover, and even If they did, they may not want to incur the extra manufacturing costs involved.
Perhaps If an additional guidance Table (linked to the data provided in Tables 1, 2, 3 & 4) was to be included in ARP7488, resolving the problem may actually get a little closer.
At least the people machining parts could be made aware of what "Break Edge Condition" we (the peeners) need to enable us to meet their requirements.
Here's hoping !
Very Old Tom
