I am having a big problem.
I have hole on cylinder at equally distributed over surface. I have to wrap that cylinder with sheet metal as in attached file and also have to match the holes on rolled sheet metal to the holes on cylinder.
if I make holes on flat pattern at equal distance, it won't match to the holes on cylinder.
if I make holes on rolled sheet, it won't be practically possible.
So please suggest if there are better way to punch the hole on rolled/bent sheet.
Thanks in advance.
