Finding the perfect die opening

By choosing a die opening as close to perfect as possible, your consistency will improve, your setup and run times will get shorter, and the risks of running into problems will be greatly reduced.


Bending Basics: How the inside bend radius forms

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.


The basics of applying bend functions

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

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

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...


The tao of forming order

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...


Taking the danger out of bottom bending

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...


Say ye shibboleth!

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...


Oversized V dies: the effects on bottom bending

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?

Skilled workers make new press brake technology even more valuable


Air forming and V-die selection


Building the perfect tool cabinet

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?

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...


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

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


Managers are not necessarily leaders

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

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

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...


How air forming works

Air forming began its rise in popularity during the mid- to late 1970s, becoming the most prevalent method of forming on a press brake.


But we have always done it this way


What the? This can't be done!

Carefully planning the forming order can make even the most daunting project less complicated and problematic.


Can I form a box that deep?

There's no reason you can't form sharp, deep boxes with a press brake consistently. You just have to be familiar with what your tooling can and can't do under certain circumstances.


Using benchmarking for bend deductions

Benchmarking is a very good idea for your operation ... just make sure your benchmarks are your own.


Bumping up large-radius bends

The step-bending method can be a good way to achieve large radii without having to spend huge sums of money on special tooling.


Reviewing bottom bending and nested parts

Looking to nest parts tightly, but can't win the battle against the material's natural grain? Take heart—bottom bending could be your key to success.


Press Brakes and (much) More

The flow of product through you shop is a key issue in determining your prosperity as a business. Drawing a little insight from the Chinese concept of feng shui might help you achieve the kind of flow you're looking for.


Mobilizing equipment-saving time and talent

It's hard to believe that machines such as press brakes and hardware-setting equipment can move around on wheels or be moved by forklift and still function correctly. But I can tell you from experience that it is true and can be done.


Fighting springback in profound radius bends

When bending sheet metal, three terms apply to the radius of the bend: sharp, radius, and profound. A sharp bend has a radius less than 63 percent of the material thickness. A radius bend has a radius between 63 percent and 10 times the material thickness. A profound radius exceeds 10 times the...


Bend deduction charts

Quite often I am asked, "Where can I get a bend deduction chart that works, one with valid numbers?" That's a good question.


Discovering the limits of press brake tooling

One of the most important aspects of press brake forming is tooling selection. What are the tools capable of? What kinds of loads can they withstand?


Brake Line: Press Brakes and More: Planning to cut corners on safety?

Press brake safety is a common sense issue.
