Bending Articles

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.

How one fabricator maintains quality in bending

March 31, 2016 | By Dan Davis

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.

Press brake bending and the notch: A deeper dive

March 28, 2016 | By Steve Benson

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.

Reggin Industries Reinvents Procedures to Create a Whale of a Sculpture

February 1, 2016 | By Sue Roberts

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.

How a plate rolling rookie becomes a guru

December 3, 2015 | By Tim Heston

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.

Press brake training: Passing the torch

December 1, 2015 | By Tim Heston

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.

Dutch metal fabrication: About flow

November 4, 2015 | By Tim Heston

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.

A grand unifying theory of press brake bending: Part II

October 28, 2015 | By Steve Benson

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.

A grand unifying theory of bending on the press brake: Part I

September 8, 2015 | By Steve Benson

Press brake guru Steve Benson proposes a new theory of bending, altering some long-held labels and definitions and introducing new formulas. Those long-held definitions worked well, but these new definitions and formulas may help a press brake technician become even more accurate in predicting how a part will form.
