The bending technology area includes all manner of machines and processes for bending sheet metal, including press brakes, folders, panel benders, corner formers, ironworkers, notchers, orbital formers, and roll benders. It also has information on accessories such as gauging and backgauging systems.

Using the 20 percent rule works well when calculating the floated radius in an air form, but what about the radius at different bend angles? To calculate this, we start with geometry to find the arc length and radius at different bend angles. We then ma

With the right tooling, you can accomplish horizontal bending—that is, where the sheet remains horizontal during the bend cycle—on the press brake. In general, horizontal bending on the press brake is accomplished with either wiping tools or rotary-style tools.

Air bending soft aluminum has such a low tensile strength that it doesn't take much for a narrow punch tip to penetrate the surface and turn the bend sharp.

To ensure you always work within the tonnage limits of your press brake and tooling, first calculate how much tonnage you need. Second, identify your tooling’s load limits. Third, calculate the sinking tonnage limit, which, if exceeded, can embed tooling into the ram or bed. Fourth, determine your press brakes’ centerline load limit.

Is producing a hem on a part more suitable for a panel bender or press brake? Does a part less than a foot long make sense for a panel bender? Can a box design with a 13-in. wall be done on a panel bender? Part designs help to reveal the answers to these questions.

A material’s minimum inside bend radius shows the smallest radius that’s physically possible in an air bend, though your machines and tooling may not be able to handle the tonnage. The recommended inside bend radius, such as those found on bend allowance charts for air bends, shows you what’s optimal in typical applications

Traditionally bending high flanges on a punch press just hasn’t been practical, but new machines and software are changing the situation. Today, flanges up to 3 inches high can be bent not by the press brake, but by special tooling on the punch press.

The time that a press brake operator spends walking to a control or maneuvering a part is time the customer is not paying for. Those seconds add up over the day and cut into a fab shop's profitability. New approaches to bending, however, can help to remedy that.

Choosing the right die for an application hinges on the tooling and press brakes you have, and the tonnage limitations of both.
