Better bend sequencing and gauging on the press brake
AUGUST 13, 2019, | By Steve Benson

A reader has trouble forming an odd part with unparallel bend line. A new bend sequence with the right gauging could be the answer.

Is the press brake or tooling really to blame?
JULY 15, 2019 | BY STEVE BENSON

You invest in new bending equipment and still have issues. What gives? It might be the material or the way it’s presented to the press brake.

Precision sheet metal bending and the V groove: Part II
JUNE 20, 20119

Last month I described the advantages, which include ease of forming and dimensional accuracy, and disadvantages, which include the low strength of a V-groove bend. This month I’ll cover exactly how to perform V-groove bends and how you can make the process as repeatable and reliable as possible.

Precision sheet metal bending and the V groove
MAY 22, 2019 | BY STEVE BENSON

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.

Don’t forget the sheet metal tolerances
APRIL 12, 2019 | BY STEVE BENSON

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

Material grain considerations on the press brake
MARCH 6, 2019 | BY STEVE BENSON

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

Why is it called a press brake?
FEBRUARY 8, 2019 | BY STEVE BENSON

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.”

Radius types formed by air bending on a press brake
JANUARY 21, 2019 | BY STEVE BENSON

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.
