Do I Need a Sheet Metal Folding Machine or Press Brake?

Written by, Andy KamashianAEA Southern Fabricating Machinery Sales, Inc. (MDNA Member Firm)  

There are many different kinds of fabrication equipment on the market intended to bend or shape metal in various ways. One question that the team here at SFMS is frequently asked is: “what’s the difference between metal folding machines andsheet metal press brakes, and which is best for my machine shop?”

At first glance, these two types of metal forming technology look similar, and even fill a similar role on the shop floor (namely, to bend metal into precise shapes). However, there are some key differences between the two types of machines that may make one better for your shop floor than the other.

What is a CNC Press Brake?

Sheet metal brakes see widespread use in manufacturing machine shops across the country. These machines have undergone numerous changes over the years, so it can be a bit difficult to generalize about their capabilities.

For example, there are four different methods that a press brake can use to apply force to a workpiece: mechanical, pneumatic, hydraulic, and servo-electric. Each of these methods has their own unique advantages and drawbacks. Hydraulic and mechanical drive systems are the most well-known types of press brakes, so we’ll use them as the primary point of comparison for this article.

The typical advantage of a CNC sheet metal brake over a metal folding machine is that the press brake has a higher tonnage than comparable CNC sheet metal folding machines—especially if it’s a hydraulic press. This allows the hydraulic press to shape much thicker metal workpieces than a CNC folding machine can handle.

What is a Metal Folding Machine?

In a lot of ways, a metal folding machine is very similar to a press brake. Even the general look of a folding machine is similar to a press brake. However, where a sheet metal brake gauges the flange and rotates the part up, the folding machine gauges the part (which is supported on the machine’s sheet support system) and turns the flange up. This is the key difference that separates the two types of machines.

Some key advantages of CNC folding machines include:

  • Size of Workpiece That Can Be Folded. A CNC folding machine’s integrated support backgauge holds up the weight of parts for the operator. Additionally, the way that folding machines bend metal makes it easier to bend multiple-setup parts that would normally require more manual interference. Because of this, metal folding machines are often able to bend larger (but not thicker) pieces of metal than press brakes.
  • Reduced Risk of Surface Damage. With limited movement between the tooling of a folding machine and the surface of the workpiece, there is typically less (if any) damage to the surface of the workpiece.
  • Multiple Station Setup Simulated in a Single Setup. CNC sheet metal folding machines can complete multiple complex operations by creating a multiple-station setup along the length of the machine. Throughout the motion of the part from one end of the machine to the other, the sheet support system holds the part while the backgauge moves it around. This allows for incredibly complex bends in metal with minimal operator input.
  • Simple Setup. Metal folding machines usually have a single set of universal tools that they use for all applications. This minimizes the setup time needed for changing tooling—as well as minimizing the storage space needed for spare tools.

Which is Better: Sheet Metal Brakes or CNC Folding Machines?

The answer depends on what kind of work you’re doing. A lot of the gaps in performance between hydraulic presses and metal folding machines can be closed by specific press brake features. For example, some sheet metal brakes have sheet lifters that support the weight of larger workpieces, making them easier for a single person to operate. Others have robotic interfaces that almost completely eliminate the need for a human operator.

In terms of accuracy, there’s not much of a difference thanks to advances in CNC systems.

Generally speaking, folding machines are better for more “delicate” work on large but thin pieces of metal that require multiple tooling changes and operations. Meanwhile, hydraulic presses are better for heavy-duty folding jobs that require a higher degree of force to complete consistently.

In many machine shops, there’s room for both types of metal fabrication equipment on the shop floor. However, if you have to choose between one or the other, ask yourself which type of work you do the most often, and which machine would be most compatible with that kind of work.

I recently stepped down as the New England Chapter Chairman. Honestly, it was difficult. It was like letting go of a child. But I feel that it’s important to make room for others to become involved. I’m still the MDNA Chapter Leadership Chairman, I lead all of the chapter chairs throughout the U.S., Canada and Europe. As part of that role, I want to encourage more members to attend chapter meetings and pursue chapter leadership roles.  There is nothing more inspiring and energizing than interacting with other dealers to share knowledge and experience. If it were possible I would attend every meeting of every chapter. I can’t emphasize enough how much I believe in our organization.

Cobots are coming: When mech, man and manufacturing combine

by Delany Martinez, originally published via Multiview

0530humanrobot

While humans are capable of astonishing endurance and precision, repetitive motion tasks are bad news for manufacturing: they aren’t just physically harmful over time, they can lead to worker burnout.

When productivity is the main focus of most industries today, what’s a large company with large needs to do when faced with human limitations?

Hiring more workers is a huge drain on finances, but going fully automated isn’t likely to win any favors with the workforce, and by extension, the public.

The solution? Cobots, or collaborative robots.

What Are Cobots?

While they’ve been around in one form or another since the dawn of robotics, true cobots are robots that are purpose-built and field-tested to perform as reliably as their human counterparts — with one important difference.

Rather than advanced technology designed to replace humans, they’re made to work with and alongside their flesh-and-blood coworkers, reducing strain of both the mental and physical variety.

Instead of relying on a pair of human eyes to scan, for example, a conveyor belt full of components to spot damages, a cobot can be armed with visual guidance software that can complete the task in a fraction of the time. This leaves the cobot’s human co-worker the freedom to complete human intelligence-requiring tasks, thus increasing overall efficiency.

What’s the Holdup on Full Cobot Adoption?

Much like any industrial place where man and machine intersect, it’s complicated. The primary concerns are ethics and safety, and those aren’t small hurdles to overcome by any stretch of the imagination.

Safety comes into play when trying to balance the superior speed, longevity and precision of cobots with potential threats to their human handlers.

For example, if a human collapses or drops an item, they aren’t typically moving at high speed with hydraulics behind them: the wrong accident at the wrong speed can end up as a deadly accident. Likewise, if a limb, hair, or a piece of clothing becomes tangled in a piece of industrial equipment, workers may be literally putting their life in robotic hands — or lack thereof — by depending on a cobot to assess and address a looming emergency by cutting power.

Robots and cobots are, after all, a product of their programming, and scenarios like these are putting a lot of faith in programmers’ ability to encode every emergency situation before it has a chance to happen.

In terms of ethics, the issue is twofold: cobots may be taking jobs that humans either are or could be doing, and their human counterparts may face reductions in pay rates or hours of availability once cobots begin taking over repetitive or menial tasks.

Though they are intended for coworking with humans, it’s not hard to imagine the tension they bring to a competitive employment market. In all likelihood, even though they’re typically nothing more than a collection of metal, silicone and wires, cobots will invite the same uneasiness in certain situations that an overambitious co-worker driving to take over your job might inspire.

These concerns aren’t slowing down the gradual spread of cobots, however: at it’s core, they’re fed by a design market buoyed by the encroaching demand for personal assistance robots in the private sector.

It’s an industry that’s projected to be worth 10 billion dollars in only a decade, which is the kind of exponential growth its adopters can only dream about for their own products. While the proverbial bugs are being ironed out, cobots have most industry experts cautiously optimistic about the possibilities.

Only time will tell, however, if cobots will ultimately get a warm welcome or a cold shoulder from their carbon-based counterparts.

Testimonial from MDNA Member—-Scott Buth, CEA, CSA, Alternative Machine Tool, LLC

At the Detroit “Weekend With The Pros” I met a new MDNA Member, Matt Reed with Benchmark Machine Tools LLC. He introduced himself as an “Expert” in Parts Washers.

I am happy to report that I kept his card, and recently I came across a late model, parts washer that I needed his help on. Our deal went very smooth and we each made enough money to pay our MDNA dues for many years to come.

Without that “face to face” meeting, I would have never pursued this machine that was out of my area of expertise. I would highly recommend that any MDNA member contact Matt Reed when they come across a Parts Washer.—-Scott Buth, CEA, CSA, Alternative Machine Tool, LLC

Mentoring Makes a Difference

Ask any accomplished person to what they attribute their success and you’ll probably hear a story about someone who helped them become the person they are today. In Screen Shot 2018-05-16 at 11.05.42 AMfact, most highly successful people have a mentor (or mentors) who took the time to share their knowledge and experience. Mentorship can come in many forms; you may choose to mentor a child, a young adult, or a less experienced professional. But whatever the case, a mentor can offer a type of constructive guidance unlike that found in any other personal or professional relationship.

Acting as a mentor can be one of the most rewarding experiences you’ll have, both personally and professionally. At the heart of being a mentor is becoming a trusted advisor to your mentee and making yourself available to pass on your knowledge and experience. You’ll offer advice and support intended to help your mentee develop in their career and as a person.

Today’s workplace is changing rapidly and in just a few years Millennials­—people born between 1977 and 1997—will make up almost half of the global workforce. This generation thinks about work in a different way and views it as an integral part of their lives rather than something they “balance” their lives against. They seek work that is meaningful and fulfilling, and they can benefit enormously from the attention and support of a mentor who can guide them toward fulfilling their goal of professional success accompanied by meaning. Acting as a mentor to a such a young professional can allow you to not only participate in their success but contribute on a larger scale as well – to your business or to your community.

A mentor must believe in the person they support both personally and professionally. The best mentor/mentee relationships require vulnerability and honesty. For the relationship to be successful, the mentee has to be comfortable enough to let down their guard and share their insecurities. The best mentors speak not only of their successes, but their failures as well. As well as passing on knowledge, a mentor must strive to inspire. Inspiration is married to emotion, and a successful mentor will infuse knowledge with emotional weight.

While long-term mentoring relationships are a deeply satisfying way to make a significant difference in another person’s life, mentoring can also be short-term or even a one-off incident. Taking half an hour for a coffee with a college student to talk about career opportunities in your field is also a way of mentoring. In my business as a machinery dealer, I often take the time to share aspects of my experience that will be helpful to my customers.

If we as a community develop a mentoring mindset, the benefits will be enormous. As the adage goes, experience is the best teacher. We need to share our experience in a way that will benefit the younger generation, but we need to do this in a way that will not alienate them. Mentoring relationships are just that – relationships – and are based on the give and take of conversation. Mentoring can be a particularly effective way to transmit knowledge to new generations.

Everyone benefits from the mentoring mindset. Young people not only acquire knowledge and skills, but they gain confidence from the relationship itself. Knowing that someone you respect and admire believes in you and is invested in your success gives a powerful boost to your motivation and confidence. And for a mentor, watching a young person succeed with the knowledge that you have played a role in that success is deeply rewarding. Everyone has something valuable to share. If we all adopt the mentoring mindset, we can each play a small role in making the world a better place one person at a time.
