2 strategies for optimizing bending operations

January 15, 2008 | By Michael Bishop

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 Bob Want

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 Steve Benson

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."

Dedicated manual tube bending

Are you dedicated to manual bending?

January 9, 2007 | By Jeffrey E. Monroe

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.

Press brake safety

Safety still pressing for press brakes

January 9, 2007 | By Kate Bachman

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.

Leaning on press brake tooling

September 12, 2006 | By Pat Campbell

Press brake tooling can play a significant role in minimizing setup, reducing WIP, increasing throughput, and minimizing waste—the goals of lean manufacturing. Some new developments are staged bending, push-button loading, sectionalized tooling, and precision-ground tools.

Fabricator puts the brake on bend inconsistency

June 13, 2006 | By Eric Lundin

Well-known for agriculture, Nebraska also has a strong manufacturing base. OEMs include Kawasaki, Husqvarna, Eaton, Thermo King, Claas, and Case New Holland. Standard Iron & Wire, a Minnesota-based fabricator, opened a manufacturing facility in Grand Island, Neb., to take advantage of this fertile manufacturing environment. Chief among its concerns was finding a press brake that would produce accurate, consistent parts. It purchased two LVD press brakes with the company's adaptive bending technology.

Taking the danger out of bottom bending

March 7, 2006 | By Steve Benson

It is all too easy to ruin a tool or upset a ram if bottom bending is done incorrectly, which is why many manufacturers do not recommend bottom bending when using their equipment or tooling. Understanding V-die selection and the effects of your decisions should be first and foremost in any bending operation, including bottom bending.
