Bending basics: Why profound-radius bending is a different animal

January 27, 2014

By:

Large or profound-radius bends are those in which the inside bend radius exceeds eight times the material thickness, but is still too small to move to the plate roll. At this point, a press brake operator has to change his mindset before proceeding. This is not a typical bending job.

Bending Basics: The fundamentals of heavy bending

January 2, 2014

By:

When bending on a press brake, thicker and harder plates require larger minimum bend radii. Finding the true minimum bend radius for steel or aluminum plate requires a little research. Nonetheless, the answers are there, waiting for you to find them.

Bending Basics: Why tonnage matters

August 1, 2013

By:

Selecting the press brake and tooling for a job involves much more than just making sure there’s enough brute force. You need to calculate how much tonnage the job requires, then determine the best machine and tooling to handle the tonnage.

Bending Basics: Why do die angles change?

June 3, 2013

By:

In air forming, the bend angle does not depend exclusively on the angle of the die. So why does the die angle change? There are two separate but overlapping answers; one relates to narrow die openings, and the other pertains to larger dies.

The basics of applying bend functions

November 9, 2012

By:

Why calculate values such as bend allowance, outside setback, and bend deductions? Because sometimes you will need to work your way around a bend on a print, and you may not have all the information you need to complete a flat pattern.

Reclaiming the disappearing press brake knowledge in your shop

January 14, 2010

By:

Expensive options on a press brake won't guarantee knowledge transfer from a veteran press brake operator to a shop floor rookie. For knowledge transfer to occur, a shop needs experienced workers that can communicate and a younger work force eager to learn because they see a future in metal fabricating.

The tao of forming order

June 12, 2007

By:

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."

Taking the danger out of bottom bending

March 7, 2006

By:

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.
