Plate Rolling Formula

 · windseaker1 Sorry for being late getting back, yes the bend formula works for rolling as well, when you roll a plate you are bending it on a large radius, the metal still has to shrink on the inside of the neutral line and stretch on the outside.To get a finished diameter that you want, you have to compensate by adding or subtracting part of the metal thickness from the neutral line.
