Bending Basics 2016

Proper measurement of formed parts
December 2016

Measuring hems, acute angles, and unparalleled flanges aren’t difficult—if you have the right tools and dimensional information, and you know how to use both properly.

What makes an air bend sharp on a press brake
November 2016

Press brake operators use rules of thumb when it comes to determining sharp bends. But what truly determines the point at which a bend turns sharp is the relationship between the punch nose radius, the tonnage required to form, and the shear strength of the material.

The meaning of the technical words mean everything
October 2016

As parts become more complicated and our machines get more sophisticated and precise, there is a real need to be much more precise in our trade-related language

Determining the root causes of bending failure
September 2016

When determining the root causes of part failure, look to not just the forming method and tooling, but also the quality of the material. A cheap material can be extremely costly over the long run.

How to locate the press brake backgauge position
August 2016

When determining the backgauge position, you need to know the outside flange dimension and bend deduction, based on the actual radius you achieve.

Applying sheet metal forming principals to plastic
July 2016

Anytime the inside radius or material thickness varies, there will be a change in the bend deduction. This is just as true when bending plastic as it is when bending sheet metal.

Tooling the heart of choosing a press brake
June 2016

When considering a new press brake purchase, focus on the tooling and forming method first. How will your staff react to changes? How steep will the learning curve be? Also, think about where your company is headed and the markets it serves.

Which press brake is best
May 2016

No press brake is best for every application, but you can find a press brake that’s best for you. To find that press brake, you need to match what’s available—hydraulic, hybrid, electric, mechanical, and other styles, along with the tooling—with what your operation needs.

Applying the 20% rule to 6061 aluminum
April 2016

Four areas to consider when bending include (1) formability; (2) thickness and bend radius; (3) tensile, yield, and elongation; and (4) how to deal with bending tempered materials. This month, Steven Benson applies these to forming 6061 aluminum.

Press brake bending and the notch a deeper dive
March 2016

Bending guru Steve Benson continues his discussion of notching, which has a symbiotic relationship with bending. Nowadays CAD systems take care of the layout calculations. Nonetheless, manual notch layout is still used for one-off products or in prototype shops.

Press brake bending and notching a symbiotic relationship
February 2016

Whether you are a press brake technician or you are programming in CAD, having a basic understanding of notching can lead to better products and more efficient operation.

10-tips for bottoming aluminum
January 2016

Bottom bending can work well for some aluminum grades, but it requires knowledgeable operators who fully grasp the bending method and know what precautions to take.
