Troubleshooting sheet metal forming: Determining the root causes of bending failure

September 15, 2016 | By Steve Benson

When determining the root causes of part failure, look to not just the forming method and tooling, but also the quality of material. Cheap material can be extremely costly over the long run.

Bending Basics: How to locate the press brake’s backgauge position

August 17, 2016 | By Steve Benson

When determining the backgauge position, you need to know the outside flange dimension and bend deduction, based on the actual radius you achieve.

Applying sheet metal forming principles to plastic

July 12, 2016 | By Steve Benson

Anytime the inside radius or material thickness varies, there will be a change in the bend deduction. This is just as true when bending plastic as it is when bending sheet metal.

Tooling: The heart of choosing a press brake

July 5, 2016 | By Steve Benson

When considering a new press brake purchase, focus on the tooling and forming method first. How will your staff react to changes? How steep will the learning curve be? Also, think about where your company is headed and the markets it serves.

Which press brake is best?

May 9, 2016 | By Steve Benson

No press brake is best for every application, but you can find a press brake that’s best for you. To find that press brake, you need to match what’s available—hydraulic, hybrid, electric, mechanical, and other styles, along with the tooling—with what your operation needs.

Press brake bending: Applying the 20 percent rule to 6061 aluminum

April 13, 2016 | By Steve Benson

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.

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.

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.
