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.

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.

Powder River, a Provo, Utah-based fabricator of farm implements, turned to KNUTH Machine Tools USA for a three-roll bender the company uses to make its round bale feeders for horses.

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.

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.

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.

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...

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.

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."

Several new breeds of high strength steels have arrived that bring with them a host of new opportunities. However, these new breeds also bring with them special challenges not common to bending mild steel, and with them, the need for new tools and new rules for proper bending.

At a time when automated equipment is the most popular and well-known method for bending tubes, there is still a demand for dedicated manual tube bending (DMTB) units to help fill a void that the use of CNC equipment sometimes creates.

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.
