The bending force can be calculated from the sheet thickness, die opening, bend length, and the ultimate tensile strength of the material. The calculator accepts measurements in decimal format based on. Calculate the required force to bend a piece of sheet metal using V-bending, a process in which a V-shaped punch presses the sheet into a V-die.

Third countries where the adequacy decision of the European Commission is not valid.

During sheet metal part bending, the inside bending surface is compressed, whereas the outer surface is stretched.

Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. This means that the authorities can have access to the data for control and monitoring purposes, against which it may not be possible K Factor in sheet metal bending is a constant used to calculate sheet metal flat length or Flat-pattern. L (mm): Circumference of the shape punched t (mm): Thickness of sheet. The high European standards of data protection do not apply. This page explains the formulas for calculating the punching pressure (P: ton).
