Subject: Punching/Perforating 6061-T6 Sheet

I am trying to punch/perforate 5mm Aluminium 6061-T6 sheet, but of course the sheet deforms a lot during the process. I have tried punching a small portion and then rolling flat and then repeating this process, but the sheet still retains the deformation. Is there a way I can soften the sheet to stop this. I have a powdercoat line with a 200 degree oven. I was thinking of putting the sheet through the oven and quenching prior to punching. Does anyone know if this will work? or does anyone have any advice?

Replies appreciated,
