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.

Press brake guru Steve Benson describes how the method of bending—coining, bottom bending, or air forming—is very influential on how an inside bend radius is achieved.

Why calculate values such as bend allowance, outside setback, and bend deductions? Because sometimes you will need to work your way around a bend on a print, and you may not have all the information you need to complete a flat pattern.

Freeing a bending bottleneck can backfire if it simply creates a severe bottleneck downstream. Bending throughput may increase, but overall throughput--the metric that really matters--may not. That’s why the best bending automation considers not only the bending department but also the throughput of the entire plant.

The FABRICATOR talks with Jeff Visser, production managers at Avon, Mass.-based BEPeterson, about the basics of plate rolling operation. Plate rolling is part art, part science. It requires skill, and not just anyone can do the job right.

Changing the die opening can dramatically change results during air forming. In precision sheet metal fabrication, choosing the correct die opening should not be a guessing game.

Iowa-based Co-Line Welding hasn't let its remote location harm its chances of success. In fact, it has embraced the challenge and has emerged as a growing business, even as it faces challenges such as rural power distribution.

Advanced controls make a highly variable process more predictable Abstract: Experience still is important when it comes to plate rolling. But the more knowledge industry has gained about the materials being rolled, the more “intelligent” plate roll systems have become.

When a fabricating operation serves customers in the defense, heavy equipment, mining, and power generation industries, you know they are working with really thick and high- strength material. It's a big job and requires big equipment. It's also the main reason that Merrill Fabricators purchased a 2,000-ton, 38-foot press brake.

Robotic press brakes may offer higher productivity and better profitability--much of which is achieved by running the press brake lights-out at top speed. In some cases, robotic press brakes can reduce per-piece costs by almost half. Still, robotic press brakes aren’t for every application.

Understanding substrates and coatings, and how the coated surface interacts with tube or pipe during the bending process, is necessary to finding a cost-effective, capable combination.

Ben endured the same frustrations many press brake department supervisors face. Operators get a print that doesn’t take the proper bend deductions into account. They fudge it, performing test bend after test bend. Productivity suffers, and the bottleneck ensues. At Ben’s shop, this all was about to change.
CAM software have made it easier and more affordable for job shops to increase efficiency and productivity without sacrificing quality. Staged bending combined with offline programming offers strategies for reducing downtime, improving part flow, and controlling costs.

Kysor/Warren, Columbus, Ga., cutomizes the refrigerated display cases and refrigeration systems for its customers. Unfortunately, it didn't have a very efficient bending operation to keep up with the production demands related to its diverse product line. To remedy the situation, the company purchased Wila precision ground tooling and installed hydraulic clamping systems on its press brakes.

Within electric brakes, bending force is distributed differently. Also optoelectronic safeguards integrate closely with the control, so much so that a light curtain or similar device has no effect on the bending cycle time. In fact, in the electric press brake arena, safety does not necessarily require a sacrifice in cycle time.

An electric press brake is not typically found in a metal fabricating operation, but that is changing as more companies realize the accuracy, speed, and energy savings that this type of device offers.
