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.

The evolution of precision bending

June 17, 2008

By:

Three decades ago bottoming with penetration, or coining, was the only way to achieve high accuracies on press brakes, and this meant fabricators endured high tooling costs. Over the years precision air bending with CNC hydraulic press brakes using precision-ground tooling evolved to become the dominant forming method in the precision market. However, it took some significant machinery advances to get there.

Special press brake tools

Specials simplify the complex, speed productivity

February 12, 2008

By:

Standardized press brake tooling, absolutely necessary for a lean organization, keeps a shop flexible, but at the same time, ignoring specials would be a big mistake. If their slightly longer setup times also lead to a drastic increase in throughput, special tools make good business sense.

2 strategies for optimizing bending operations

January 15, 2008

By:

Fabricators typically encounter bottlenecks during setup and production in their press brake bending operations—obstacles that lead to downtime and fewer operators actually processing material. Representatives from Amada, LVD Strippit, Bystronic Inc. addressed these issues in a recent presentation. The two largest problems? Performing non-value-added steps and having to compensate for material variations. Fortunately, some new technologies and two key strategies can help fabricators optimize their press brake operations in these areas.

Automatic or manual?

October 9, 2007

By:

While automation can increase throughput and reduce labor, it doesn't solve manufacturing problems. A manual process that produces poor-quality or inconsistent parts will simply do so at a faster rate if automated. Understanding the process and process variables is the key to troubleshooting problems and resolving them to get the maximum gain from automation.

Dealing with Mother Nature's wrath

October 9, 2007

Protecting a two-mile-long, 10-lane bridge from earthquake damage is not an easy task. Replacing the eastern span of the San Francisco-Oakland Bay Bridge requires the talent and time of numerous design firms and fabricators and tens of thousands of workers. One of the more interesting fabrication...

Toro trims waste with press brake tooling upgrade

September 11, 2007

Outdoor equipment manufacturer Toro Co. regularly sends out bids for parts, forcing its own manufacturing plants to compete with outside vendors. Toro's manufacturing plants face the same competitive pressures as any other manufacturer, so its plant in Shakopee, Minn., analyzed its forming operations and decided to replace its press brakes and upgrade its tooling.

The tao of forming order

June 12, 2007

By:

Is the starting position of the flat part facing the wrong way or upside down to your natural flow? Are you working from left to right when your natural motion is right to left? If you are, you're fighting the current rather than letting the current do the work. Set up the press brake in such a manner that you work with your natural flow; by not interrupting your "chi."

Press brake safety

Safety still pressing for press brakes

January 9, 2007

By:

The leading trend in press brakes safety is to ensure safety without sacrificing speed or hampering operators' ability to work efficiently, say press brakes manufacturers. This starts with tooling, including segmented or sectionalized tooling that is lighter and easier to handle; safety features that prevent unsecured tooling from falling, and fewer tool changes. It is further achieved with light curtains, camera and vision-based sensors, and mechanical side and rear guards, as well as automation and robots.
