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.

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 latest advances in adjustable V dies have finally brought the kind of flexibility to plate bending that those in the precision sheet metal arena have enjoyed for years.

Plate and angle rolling remains extremely dependent on operator skill. According to a U.S. roll shop roundtable discussion held at a Davi angle rolling event in Italy, that skill really is what sets a custom rolling operation apart.

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

Phoenix Products has more than doubled its size during the past year, and much of that growth has to do with tackling an unusual niche: the bending of long, skinny parts.

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

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.

In metal fabrication, companies need technical skill, but there’s a humanity to the skill that’s often overlooked. It’s about the relationship between the technician, his machine, and the workpiece.

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.

Think of how fast modern laser cutting is; now think of a typical press brake. There’s no contest. With this in mind, how can a fab shop best manage part flow? Elements of quick-response manufacturing (QRM) can help.

In large-workpiece bending, material handling and tooling changeover can take serious time. Shorten that time, and bending throughput levels, even for the largest jobs, can jump significantly.
