Sheet Metal and Pipe Forming

These calculators size forming jobs. Get air bending force for a press brake, punch force for a hole, the blank diameter for a drawn cup, the length of strip in a coil and the arc length and setback of a pipe bend.

Tools in this group

• Blank Size Calculator (Deep Drawing) — Enter the cup diameter and height, with a corner radius or flange if it has one, to get the blank diameter and the draw ratio.
• Coil Length Calculator — Get the length of strip in a coil from its outside diameter, inside diameter and thickness, or from its weight, width and material.
• Pipe Bending Calculator — Enter the centreline radius and bend angle to get the arc length, setback and gain, or plan an offset with the distance between bends and shrink.
• Press Brake Tonnage Calculator — Enter the sheet thickness, V-die opening, bend length and tensile strength to get the air bending force per foot (or metre) and in total.
• Punching Force Calculator — Choose the hole shape, enter its size, the sheet thickness and the material's shear strength to get the punch force in kN and tons.
