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 manipulate these results by factoring in real-world bending conditions.

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.

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.
