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.

Say ye shibboleth!

November 8, 2005

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.

It's all about tool selection -- or is it?

May 10, 2005

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...

Building the perfect tool cabinet

March 25, 2004

By:

Have you ever wondered about the best way to store your press brake tooling? An expensive part of your press brake operation, tooling is damaged enough just by daily wear and tear and accidents. You don't want to damage it further by storing it improperly.

Why should you care about inside bend radii?

January 29, 2004

By:

Operators, designers, and engineers, why should you care about the inside bend radius if the customer doesn't? Because, ultimately, just how easy or difficult it is to produce a part depends on decisions made during the design stage. Misunderstanding terminology, process capabilities, or production methods can lead to mistakes that can make production more difficult. The most common mistake is incorrectly calculating and achieving the correct minimum inside bend radius.

John Henry's last challenge or a Rube Goldberg device?

September 10, 2003

By:

Picking the right press brake has never been an easy task and it continues to get harder all the time. New hydraulic systems offer unbelievable control and sophisticated hydraulic valving that were unimaginable just a few short years ago.

Die width selection

July 24, 2003

By:

Most designers and engineers usually place very little importance on achieving the correct inside radius of a formed part. Why? Because the functionality of the part is unaffected if the specified inside radius is 0.062 in. and actual measured inside radius is 0.078 in. So why do we care about...

Managers are not necessarily leaders

June 26, 2003

By:

Often we are told that leadership is the key to the success of any business or organization. What is leadership? Is it the same as management? And what separates would-be or so-so leaders from world-class leaders?

Making your own punch and dies

May 29, 2003

By:

How many times have you looked through huge piles of blueprints for a prototype part or short-run job and thought, "If only I had that tool, this job would be a piece of cake?"

Gauging difficult parts at the press brake

March 27, 2003

By:

Gone are the days when engineers and draftsmen slaved for hours over drafting boards with a pencil and slide rule in hand (does anyone remember slide rules?). Today we've moved beyond slide rules and even beyond hand-held calculators to personal computers and mainframes to do much, if not all, of our design work. CAD and CAM software has made this possible.
