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.

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.

Ron Covell’s 50-year career manually building autobodies for street rods, dragsters, and motorcycles is impressive, to say the least. But he doesn’t plan on hoarding all of the expertise he’s garnered over the years. His latest passion, of the last 20 years anyway, has been sharing information in his traveling workshops to current or up-and-coming autobody enthusiasts. It’s what he hopes is his longest and most impactful legacy.

An organized workspace is an efficient workspace. Press brake technicians should have all the tools they need to perform a changeover. Unlabeled punches and dies, stored haphazardly on a rack, on the floor, or in boxes, only make their jobs harder.

Customers want parts right away, and newer laser cutting technology is producing parts quicker than ever before. If a fabricator wants the bending department to keep up, it needs press brakes that can bend parts quickly. Even with the increased bending productivity, however, fabricators don’t have to sacrifice safety.
