Bending is a manufacturing process that produces a vshape, ushape, or channel shape. In addition, thanks to the flexibility of numerical models, estimates were made of strain and temperature fields in the ironing process for a much wider range of input parameters than the physical experiments. Joggling, also known as joggle bending, is an offset bending process in which the two opposite bends are each less than 90 see following section for how bend angle is measured, and are separated by a neutral web so that the offset in the usual case where the opposite bends are equal in angle is less than 5 workpiece thicknesses.
