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.

Bending Basics: How the inside bend radius forms

January 10, 2013

By:

Press brake guru Steve Benson describes how the method of bending—coining, bottom bending, or air forming—is very influential on how an inside bend radius is achieved.

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.

Bending basics: Dissecting bend deductions and die openings

September 3, 2012

By:

Changing the die opening can dramatically change results during air forming. In precision sheet metal fabrication, choosing the correct die opening should not be a guessing game.

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.

By:

Properly trained press brake operators understand the nuances of tapers. Armed with this knowledge and following a five-step process that includes inspecting tooling and materials, precise setup, checking the part, and making necessary adjustments, these skilled workers can complete machine setup and produce quality parts in minimal time.

Oversized V dies: the effects on bottom bending

August 9, 2005

By:

Using oversized V dies in bottom bending can damage press brakes and tooling, but used properly, these dies can help compensate for springback.

By:

Figure 1 The radius gauge fits squarely into the bend. Air forming, bottom bending, and coining are different forming methods that can be used to create various bends—sharp, radius, and profound-radius. Throw in a mix of operators and engineers with different ideas of what each...

Safety faux pas

February 8, 2005

By:

Figure 1 No Triggering Device Protection In the more than 25 years that I've been in the precision sheet metal trade, I have seen many examples of safety faux pas. Most were mistakes and oversights committed because of inattentiveness, lack of training, and inexperience. However,...

Skilled workers make new press brake technology even more valuable

September 14, 2004

By:

This article grew out of an FMA discussion board posting about new press brake controllers and software in which someone asked, "Do I really need all of these bells and whistles?" A profound fact of today's technology-intensive world is that skilled press brake operators are now unnecessary. After...

Air forming and V-die selection

May 4, 2004

By:

Air forming, bottom bending, and coining are metal forming methods. Air forming, the most common, is a three-point operation. The actual inside radius produced is based on a percentage of the V-die width, regardless of the sharp–radius relationship. Selecting the correct die width can be...
