If you pick the right offset tool for the job, you'll find you will be able to produce many different offset geometries quickly and safely.

In this excerpt from Sheet Metalworking: State of the Art, the concept of adaptive forming, a special form of air bending, is introduced and explained.

Properly setting up the tooling on a tube or pipe bender can be a straightforward process, but misunderstandings and shortcuts can lead to poor setups. The wiper die’s rake angle is one such setting. Operators should beware that setting the tool to a specific gap at its trailing edge can lead to inconsistent setups.

Press brake setup is a critical part of doing any bending job correctly. By focusing on a few key areas—selection of tools and forming processes, easy-to-understand setup sheets, and ISO documentation—the press brake operator is in a much better position to succeed.

BEPeterson, Avon, Mass., used to be a weld shop. Most of the work was seasonal, which isn’t really a solid foundation for growth. The fabricator changed that with a commitment to diversification. Today the company has three unique business units: power utility, medical, and pressure vessels.

Bending plate is not a process that metal fabricators consider to be a highly efficient one. The blanks typically are large and awkward to handle. Fortunately, the proper tooling strategies can help.

Large or profound-radius bends are those in which the inside bend radius exceeds eight times the material thickness, but is still too small to move to the plate roll. At this point, a press brake operator has to change his mindset before proceeding. This is not a typical bending job.

Robbins Manufacturing of Fall River, Wis., has invested in an extensive training program, including machine-specific training, especially on the press brake. The company also has invested heavily in new technology, including a brake with automatic tool change. Both investments are paying off.

When bending on a press brake, thicker and harder plates require larger minimum bend radii. Finding the true minimum bend radius for steel or aluminum plate requires a little research. Nonetheless, the answers are there, waiting for you to find them.

The automatic backgauge, which began to permeate shop floors in the 1970s, really was a revolutionary step forward. In fact, without this step forward, sheet metal fabrication wouldn’t be the business it is today.

Shop floors are filled with advanced technology, and this includes the press brake department. As bending guru Steve Benson explains, you still need skilled technicians to make the best use of that technology.

Plate rolling is not as simple as using a press brake to make a 90-degree bend on a small piece of metal. With the right equipment, however, a fabricator can learn to become a very good plate roller in a short amount of time.

Bending large sheet metal parts does not represent the majority of work for most metal fabricators, but it can be a significant portion for those shops that have the capability to do it. These equipment considerations and processing tips can help make a big bending job easier to accomplish.

In the early 2000s, Innovated Machine & Tool Co., Newport News, Va., tried a robotic press brake for a bending job and found that it worked out well--for that job. Unfortunately, when the contract ended, so did the useful life of that robotic press brake. Since then, the shop hasn't had to worry about machine obsolescence because its panel bending technology is helping it stay on top of all sorts of bending work.

Selecting the press brake and tooling for a job involves much more than just making sure there’s enough brute force. You need to calculate how much tonnage the job requires, then determine the best machine and tooling to handle the tonnage.
