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.

Sick of setup time at the press brake

May 2, 2013 | By Dan Davis

Alto-Shaam, Menomonee Falls, Wis., needed to find a way to reduce setup times for its low-volume, high-mix work associated with fabricating parts for food service equipment. The company found its answer with a panel bender that management had seen in action at a FABTECH tradeshow several years before.

How automation makes best use of talent

March 7, 2013 | By Tim Heston

A high-product-mix manufacturer chooses robotized bending not because it lacked a skilled workforce, but because it wanted to make the best use of the talented workforce it already had.

Tooling changeover can be a pressing issue

March 7, 2013 | By Sue Roberts

Press brake manufacturers have responded to industry’s need to produce small batches of parts that require frequent tooling changes by designing options and systems to reduce setup time by managing, storing, and automatically changing upper and lower tools. Operators can spend less time physically involved with setup and more time with the profit-making bending process. Reduced margin for error and less scrap are added benefits. However, there are steps that can be taken to reduce setup time without investing in new press brake equipment.

Bending Basics: How the inside bend radius forms

January 10, 2013 | By Steve Benson

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.

The basics of applying bend functions

November 9, 2012 | By Steve Benson

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.

Bending for the internal customer

October 12, 2012 | By Bill Bossard

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.

Plate rolling rolls on

June 29, 2012 | By Francesco Massa

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.

Big bending jobs lead to high-tonnage press brake

May 1, 2012 | By Dan Davis

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.

Justifying a robotic press brake

April 3, 2012

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.

Bending software streamlines press brake department

February 28, 2012 | By Scott Ottens

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.
