Flange length - The length of either of the two flanges, extending from the edge of the sheet.This line defines the edge of a mold that would bound the bent sheet Outside mold line - The straight line where the outside surfaces of the two flanges would.Bend line - The straight line on the surface of the sheet, on either side of the bend, thatĭefines the end of the level flange and the start of the bend.Aīend can be characterized by several different parameters, shown in the image below. Bent partsĬan be quite small, such as a bracket, or up to 20 feet in length, such as a large enclosure or chassis. A bending operation causes deformation along oneĪxis, but a sequence of several different operations can be performed to create a complex part.
Bending is a metal forming process in which a force is applied to a piece of sheet metal,Ĭausing it to bend at an angle and form the desired shape.
