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.

As cutting productivity rises to unprecedented levels, fabricators tackle their next bottleneck: bending. Today, panel benders, folders, and press brakes with automated tool changing are expanding forming possibilities and making new levels of bending productivity possible.

Four areas to consider when bending include (1) formability; (2) thickness and bend radius; (3) tensile, yield, and elongation; and (4) how to deal with bending tempered materials. This month, Steven Benson applies these to forming 6061 aluminum.

DeWys Manufacturing, Marne, Mich., used to rely on quality personnel running all over the plant to check parts, but that caused downtime as people waited for the quality check. As the company explored lean manufacturing and refined its training process, it sought to make quality the job of everyone, not just a select few. The results of this thinking are particularly evident in the press brake department.

Bending guru Steve Benson continues his discussion of notching, which has a symbiotic relationship with bending. Nowadays CAD systems take care of the layout calculations. Nonetheless, manual notch layout is still used for one-off products or in prototype shops.

Whether you are a press brake technician or you are programming in CAD, having a basic understanding of notching can lead to better products and a more efficient operation.

The beauty and grace of a baleen whale were the inspiration of the Sei sculpture designed by Michael Yahgulanaas and fabricated by Reggin Industries, Calgary, Alberta, for the McArthurGlen Designer Outlet Mall at the Vancouver Airport. Fabricating the smooth, curved lines of the sculpture with a mirrored stainless steel exterior within a tight time frame required a disciplined, revised production flow and innovation.

Bottom bending can work well for some aluminum grades, but it requires knowledgeable operators who fully grasp the bending method and know what precautions to take.

This month Steve Benson summarizes his grand unifying theory of radius, bend deduction, and die selection with a review and complete rundown of the bend calculations, from estimating springback to working the bend functions.

How does a plate rolling rookie become a guru? According to Ken Pecho, project engineer at Chicago Metal Rolled Products, it requires good communication. So how do you really define good communication? For plate rolling (and many other shop skills), you can break it down into three critical components: collaboration, observation, and patience.

Southern Metalcraft Inc.’s press brake veteran will be retiring at the end of 2016, and he is now passing the torch to someone who never worked on a press brake until 2009. So how did the rookie learn so quickly? Technical aptitude plays a role. But more important than that, the veteran and rookie get along and just work well together.

In this installment of the Grand Unifying Theory of bending, press brake guru Steve Benson describes bending calculations for aircraft tooling. He also covers the basics of bottoming

One theme carried throughout a recent LVD press tour of custom fabricators in Holland: With fast changeover and the ability to access the right information at the right time, even a custom fabricator with the highest product mix can achieve smooth part flow.

Radius bends—defined here as any bend with an inside radius greater than 125 percent of the material thickness—require careful calculation, not only because of their significant springback, but also because of the tooling these bends require. This includes the use of relieved dies.

Improved tool storage at the press brake, easier tool identification, fast tool loading/unloading (including heavy tools), and proper positioning of tooling in the press brake can make life easier for any press brake operator--experienced or not.
