Form Roll, I need to roll the edge of a CNC lathed part, on the lathe

[joej66]

I am trying to develop a process to roll the edge of a 17-4PH Lathed part. The part is approx 1.25 in. in DIA. the lip is on the od of the part. The wall is approx. .020 thick by .075 long. the edge is tapered.

What temp should the part diam. be in order to form roll the edge down.

Does anyone know of a tooling mfg. that could make the form rolling tool?

If you are going to form you should work in the over aged condition, that has the best ductility.
