Cutout over a curved sheet metal part

How would you design this part?


I need a perfect d=10.2 mm circle.


I made a d=1mm cutout over the rolled sheet metal, unfold, cutout a d=10,2 mm and fold again.


Is it correct or is there a better workaround?


If I don't make a perfect circle. The punch/laser machining guys will use the laser for cutting the ellipse and obviously is faster and cheaper using punch tools for cutting the circle.


P.S.: If you know how to convert to sheetmetal the first feature I would be very grateful to listen to how :-)


Thank you
