Need to produce a very small-radius bend while keeping the outside surface of the bend free of cracking and deformation? V-grooving could be for you.

Tolerances in bending involve more than just the angle tolerances shown on the print. Materials also have tolerances, both in thickness and yield strength.

If you’re bending cold-rolled steel and other anisotropic material, inconsistent grain direction can lead to inconsistencies at the press brake.

Why is a press brake called a press brake? In short, the verb “brake,” as used in sheet metal shops, comes from a Middle English verb that meant “to bend.”

Press brake guru Steve Benson describes five types of radii that can be formed in air bending, from sharp bends up to profound radius bends.

Old press brakes with planer tooling still can produce good parts. You just need to maintain them properly, realize their limitations, and account for the inconsistencies of planer tooling.

Columnist Steve Benson helps a reader dial in the 20 percent rule to better predict the inside radius when air forming.

Bending guru Steve Benson continues his deep dive into the k-factor, arguably the most important variable in precision sheet metal fabrication.

The k-factor is like the roux of a good gumbo. The better the roux goes with all the ingredients—material type, thickness, and grain direction; forming method; tooling; bend direction; and more—the tastier the gumbo, and the better your press brake operation will be.

A reader asks bending guru Steve Benson about the challenges behind forming 6061-T6 aluminum. The challenges are many, but they can be overcome.

Your press brake operation is putting a crease along the inside bend radius. How do you prevent this? Make sure the force needed to pierce the material is more than the force needed to form it.

Columnist Steve Benson describes three best practices that will improve any press brake department: good setup sheets, smart backgauging, and efficient methods for dealing with material thickness variation.

The inside bend radius has far too many variables to be a metric for checking the health of your press brake, but it can check the health of your tooling. A good bending operation needs both.

Want to calculate your bends with precision? Then run your bend calculations using a K-factor that takes your application’s variables into account. Even better, you can turn to something that’s even more precise—the Y-factor.

If a shop moves from conventional fabrication toward the precision market, an investment in precision-ground tooling can make a bending department much more efficient.

President Trump’s ever-changing tariffs have created a wild ride for stamping manufacturers buying steel and aluminum, supplying the auto industry, and sourcing from and selling to the global market.

The Additive Report focuses on the use of additive manufacturing technology in the real world of manufacturing. Today’s manufacturers are using 3D printing technology to create tools and fixtures, and some are even using AM for high-volume production work. Their stories will be covered here.
