Big Picture Trends Affecting Machine Shops

June 20, 2016 / , , , , , , , , ,


In today’s lean manufacturing world, managers and executives are encouraged to “stay grounded” and find out first-hand what is happening in their operations. As we stated in a previously published blog, improvement decisions can’t be made in an ivory tower. Instead, lean experts advise manufacturing executives to make the time to visit the shop floor—also known as taking a “gemba walk”—so they can see their operation from the front lines.

At the same time, however, today’s competitive market requires leaders to keep a pulse on “megatrends” so they can create innovative, strategic solutions that balance internal efficiency with external demands. In other words, even small shop managers need to be tracking larger scale trends so they can stay competitive and respond to changing customer expectations and an evolving manufacturing industry.

According to Modern Machine Shop, the recent MFG Meeting in Palm Springs, CA highlighted some bigger picture trends that are shaping manufacturing. Below is a summary of three key trends, as reported by Editor Mark Albert:

A contributed article appearing in IndustryWeek echoed similar trends, but zeroed in on the effect “Big Data” will have on manufacturing. “The ability to collect and analyze large volumes of data in economic transactions has revolutionized customer care in the retail and finance sectors,” the article states. “In manufacturing, Big Data will accelerate the integration of IT, manufacturing, and operational systems on the shop floor and lead to better forecasting and understanding of plant performance.”

The IW article also noted the changing demographics of the workforce—a trend of which most machine shops and industrial metal-cutting companies are well aware. According to the eBook, Five Performance-Boosting Best Practices for Your Industrial Metal Cutting Organization, by the year 2020, most companies will have five generations in the workplace. This may certainly create some challenges, but as the eBook explains, managers can also use this demographic mix to their benefit by leveraging the different strengths found within their multigenerational workforce.

“While younger, less experienced workers may lack industry knowledge, they are typically more technology savvy and more willing to embrace new techniques,” the eBook explains. “Seasoned workers, on the other hand, may be resistant to both change and technological improvements; however, they typically have a vast amount of experience and loyalty, and may be able to mentor new employees.”

Of course, these are just some of the big-picture trends affecting machine shops, and many are already responding. As reported in our “Machine Shop Outlook for 2016,” a benchmarking study from Modern Machine Shop revealed that leading U.S. machine shops this year are focusing on workforce training and talent to close the skills gap, improving shop floor practices to optimize processes, and investing in future technology to stay competitive.

How is your shop responding to these megatrends?

Making Continuous Improvement Work in Your Fabrication Shop

June 10, 2016 / , , , , , , ,


For the last few years, manufacturers have touted continuous improvement as a top priority and company goal. Case in point: two of the three industrial metal-cutting companies featured here in a case study on top performers listed continuous improvement as an imperative operational strategy and best practice that sets their metal-cutting shops above the rest.

However, the truth is while many managers understand the theory of continuous improvement, many are still unsure of how to successfully put it into practice. In fact, research has found that the success rate for continuous improvement efforts is less than 60 percent.

What is continuous improvement? Is it simply a set of tools to adopt and implement—or is there more to it than that? Below is a brief overview of this often over-used, misunderstood term, and some tips for putting it to work in your fabrication shop.

Defining Continuous Improvement
Continuous improvement (CI) is defined by ASQ as an ongoing effort to improve a product, service, or process. Most companies achieve this by either adopting one of the well-known continuous improvement methods or through the combination of two or more tools.

According to ASQ, the most widely used tool for continuous improvement is a four-step quality model—the plan-do-check-act (PDCA) cycle, also known as Deming Cycle or Shewhart Cycle. Other widely used tools include Six Sigma, lean manufacturing, and Total Quality Management.

Even so, as an article from Canadian Metalworking points out, it’s important for managers to remember that continuous improvement is more than just a collection of tools. “Many people mistake the individual tools of continuous improvement for the most important part of the program,” the article states. “The tools are just the most visible part that we can see, and subsequently adopt.”

Personnel development, the Canadian Metalworking article continues, should actually be the central focus of continuous improvement. This means that people—not tools—need to be the primary focus of your CI efforts.

People before Process
When focusing on personnel development, there are three areas in particular that managers should focus on. As the following explains, teamwork, management, and culture all play critical roles in a successful CI program:

Sustainable Success
In theory, the concept of constantly improving a business sounds good. However, the truth is that many managers don’t fully understand what it takes to implement a successful CI program.

To be effective, continuous improvement needs to be about more than just a set of process improvement tools. While a tool may help you achieve short-term improvement, it is the people behind the effort that will help you realize continuous, ongoing improvements. Managers who focus on building a strong team and company culture fully devoted to continuous improvement will see long-term, sustainable results.

Predictive Maintenance Helps Metal Service Centers Reduce Downtime

June 5, 2016 / , , , , , , , , , , , , , , ,


Manufacturers know that downtime results in lost productivity and profits. However, thanks to technological advancements in predictive maintenance, service centers and other industrial metal-cutting companies can nearly eliminate downtime altogether.

Unlike preventative maintenance, which uses anticipated and planned downtime to prevent unplanned breakdowns and minimize cost impacts, predictive maintenance aims to predict breakdowns before they even occur. Software and sensors collect data, and algorithms identify not only the anticipated failure, but also calculate the probable time that failure will occur. This enables companies to repair or replace parts before failure and helps eliminate both planned and unplanned downtime.

Several industries are adopting predictive maintenance as part of their operations. An article from the Harvard Business Review provides a few examples:

The manufacturing industry is also adopting predictive maintenance, but research shows it is doing so at a slower rate compared to others. For example, a recent survey by the Manufacturing Enterprise Solutions Association and LNS Research concluded that manufacturers have some work to do to catch up to current capabilities—only 14 percent of survey respondents said they used manufacturing data in their analytic program.

Of course, building a predictive maintenance program requires both time and money, but many manufacturers are finding that the benefits outweigh the cost. An article from American Metals Market lists just a few of the many potential benefits of using predictive maintenance:

According to the AMM article, several metals leaders are reaping the rewards of predictive maintenance, including:

The trend is also starting to gain traction in industrial metal cutting. The LENOX Institute of Technology’s benchmark study of more than 100 metal service centers and other industrial metal-cutting organizations found that companies are gaining additional productivity and efficiency on the shop floor by “investing in smarter, more predictive and more agile operations management approaches.”

While there is no question that predictive maintenance is proving beneficial in the metals industry and beyond, some companies may be hesitant to adopt the technology due to the investment and the training required for implementation. However, if your goal is to reduce downtime and increase the chances of future success, this may be one technology worth considering.

Building Effective Continuous Improvement Teams within Your Industrial Metal-Cutting Operation

May 15, 2016 / , , , , , , ,


There’s a well-known saying that a business is only as good as its people, and industrial metal-cutting operations are no exception. Effective teams are an essential component to the overall success of a business, especially one that aims for continuous improvement.

According to the eBook, Five Performance-Boosting Best Practices for Your Industrial Metal-Cutting Company, “continuous improvement initiatives need to be a team effort to be sustainable.” In other words, to improve your industrial metal-cutting operations to its fullest potential, you need to have the right people with the right skills to keep your plan on course. Without a team backing the process, the very notion of any continuous improvement program is impossible.

Of course, the real challenge is building a strong continuous improvement team. As a recent article from IndustryWeek points out, just because a company works in teams doesn’t mean it is good at teamwork. Management’s goal has to be more than simply building a team; the goal needs to be building an effective team.

What does a successful continuous improvement team look like? An article from the Institute of Industrial and Systems Engineers provides nine best practices used by highly effective continuous improvement teams:

  1. Look at more than just numbers. Continuous improvement is very metric-driven, but don’t forget about inefficiencies that might show low numbers or those that aren’t easily quantified such as infrastructure, sanitation and preventative maintenance.
  2. Develop cross-functional teams. Expand your team to include more than just members from operations, engineering and quality. Cross-functional teams discuss and agree to solutions minimizing negative impacts before they happen.
  3. Define goals. Know what you want to achieve and how you are going to achieve it. More importantly, make those goals focused and achievable. Focusing on one set of challenges will allow you to see improvements quickly.
  4. Use automated KPIs. Collecting the right information at the right time will enable you to improve performance and eliminate inefficiencies.
  5. Utilize operators selectively. Operators are there to operate the line, not report data. While they can provide focused information when needed, don’t abuse their knowledge.
  6. Determine root causes. Whenever an issue arises, conduct a root cause analysis to find the real reason why it occurred.
  7. Focus on impactful, measurable change. You’ve analyzed the root causes, utilized cross-functional teams to prioritize issues and established a consensus for your process change. Now is the time to implement it and make sure it has the impact you thought by checking in with your team, tracking metrics and making adjustments as needed.
  8. Implement incentives that motivate. Reward hard work with an incentive program. Improve your operations by investing in your people.
  9. Benchmark. Competition is healthy. Know what others in the metal-cutting industry are tracking and their results. Use the comparison to further improve your operation.

Do you have a continuous improvement team? What habits do you feel make it an effective team?

Software Tools Help Fabricators Improve Productivity

May 10, 2016 / , , , , , , , , , ,


As fabricators continue to seek new ways to optimize their operations, many are turning to software. Whether using it to connect the plant floor to the front office, or to measure key performance indicators (KPIs), data shows that more and more fabricators view software as a smart—and necessary—manufacturing tool.

For example, according the “2016 Capital Spending Forecast” from the Fabricators & Manufacturers Association International, more than 94 percent of survey respondents said their software spending this year would either remain the same or increase. This is significant, especially as more and more reports show that many companies are pulling back on spending this year.

A separate benchmarking survey from Modern Machine Shop shows that leading shops are more likely to utilize advanced software programs in their operations. Specifically, the survey found that top-performing machine shops (referred to as “top shops”) are more apt to utilize software solutions like enterprise resource planning (ERP) and toolpath simulation software in comparison to other shops.

Valuable Solutions
While there are many reasons software is becoming a valuable tool for manufacturers, for fabricators, a lot of it has to do with evolving customer demands. “As more custom fabricators are taking on more design work—beyond just design for manufacturability—engineering and estimating functions become more complex, especially as that work focuses on more subassemblies and full assemblies that call for multilevel bills of material and a multitude of sourced parts,” states a report from thefabricator.com. This, the article continues, is causing shops to invest in better methods of communication, as well as software tools like CAD/CAM, nesting systems, and ERP.

The good news is that as more manufacturers embrace software, the more tools are being developed—both by software designers and supply chain partners. Like consumers, industrial manufacturers are finding that where there is a need or challenge, there is indeed “an app for that.”

In metal cutting, specifically, there are several tools fabricators can use to help optimize their operations—many of which are free of charge. Below are two in particular that fabricators may find helpful:

Enhance Your Toolbox
Having the right tool for the job has always been a critical part of any metal-cutting operation, but fabricators are finding that it pays to have more than just hardware in their strategic toolbox. While it will never replace the important work machinery and other hardware tools perform on the shop floor, software tools can further optimize cutting operations by measuring important metrics, analyzing job trends, automating certain functions, and educating operators on proper cutting parameters. Although some software programs can be costly in terms of both money and training time, there are plenty of free tools available that can help even the smallest fabrication shop improve their operations.

How to Use Data in Your Industrial Metal-Cutting Organization

May 1, 2016 / , , , , , , , , , ,


As companies look for new ways to stay competitive, more and more manufacturers are utilizing “big data” and analytics in their operations. In fact, according to the results of a survey from Deloitte and the Council on Competitiveness, these types of advanced technologies have the power to put the U.S. back on the map as the most competitive manufacturing nation.

“CEOs say advanced manufacturing technologies are key to unlocking future competitiveness,” the report summary states. “As the digital and physical worlds converge within manufacturing, executives indicate the path to manufacturing competitiveness is through advanced technologies, ranking predictive analytics, Internet-of-Things (IoT), both smart products and smart factories via Industry 4.0, as well as advanced materials as critical to future competitiveness.”

Specifically, the report states that the application of these more advanced and sophisticated product and process technologies will help the U.S. and other traditional manufacturing powerhouses of the 20th century (i.e. Germany, Japan, and the United Kingdom) reclaim their spots as the most competitive nations in 2016. The U.S. in particular is expected to take the number one spot away from China by the end of the decade.

What does this mean for industrial metal-cutting organizations? It means that if you haven’t already considered using data and software analytics in your facility, it may be time to revisit the idea. If data-driven manufacturing has the ability to make nations more competitive, that certainly says something about what it can do for individual companies.

Metrics that Matter
For many industrial manufacturers, the thought of using data may seem a bit daunting; however, it doesn’t have to be as complicated as it sounds. For example, a metal service center featured here in a white paper started by developing an internal software system that automatically tracks the number of square inches processed by its existing sawing equipment. At any point, the manager can go to a computer screen, click on a particular band saw or circular saw, and see how many square inches each saw is currently processing and has processed in the past. Gathering this type of data allows the service center to easily track trends and quickly detect problem areas.

Richards Industries, a Cincinnati, OH, company that manufactures industrial valves, is using data in a similar way, according to a recent article from Modern Machine Shop. Although the company has been practicing lean manufacturing for years, it recently installed a machine-monitoring system that enables shop floor personnel to track activities and record the performance of its machine tools. “Like readings from a Fitbit or Jawbone, the data gathered and analyzed by this system is making the company more aware of how well machine time and manpower count toward productivity,” Modern Machine Shop reports.

Of course, these are just two examples. There are many other ways manufacturers can utilize data and advanced analytics to improve their operations. An article from IndustryWeek calls out a few key metrics industrial metal-cutting companies should consider as they implement data and analytics tools into their factory:

Get Going
Whether you decide use data to gain productivity, monitor machines, or improve quality, the point is that data-driven manufacturing is here, and companies big and small are taking advantage of its many benefits. If you haven’t jumped on the bandwagon yet, don’t get overwhelmed. Just get started.

How are you utilizing data to improve your operations and stay competitive?

2016 Industrial Metal-Cutting Outlook

April 1, 2016 / , , , , , , , , , , , ,


Although many hoped that 2016 was going to be a year of full recovery and growth, expansion in the industrial manufacturing sector has been slow moving. High inventory levels, a strong dollar, falling commodity prices, and a slowdown in China have left many industrial metal-cutting companies disappointed and more than a little cautious.

Slow Growth
Evidence of slow growth started at the end of 2015. According to estimates from the Manufacturers Alliance for Productivity and Innovation (MAPI), manufacturing industrial production was unchanged from the third to the fourth quarter of 2015. Monthly data has shown erratic patterns of growth and decline that have pretty much cancelled out any movement forward—a trend that is expected to continue.

“We expect the volatility to continue through the first half of 2016, a situation that will result in essentially no manufacturing production growth,” MAPI stated in a recent report. “Manufacturing production should be flat in the first and second quarters of 2016 before accelerating to a 3-percent annual rate in the second half of 2016.”

For the entire year, MAPI expects manufacturing production to decelerate rather than accelerate compared to 2015. “Production increased 2 percent last year, and we forecast only 1.1-percent growth in 2016,” MAPI states. The good news is that MAPI predicts growth in industrial manufacturing of more than 2 percent for both 2017 and 2018.

Unfortunately, the forecast for steel demand also shows little to no growth, although 2016 is expected to be an improvement over 2015. According to the Short Range Outlook 2015-2016 from the World Steel Association (worldsteel), global steel demand decreased 1.7 percent in 2015 but is expected to grow by 0.7 percent in 2016.

“It is clear that the steel industry has, for the time being, reached the end of a major growth cycle which was based on the rapid economic development of China,” Hans Jürgen Kerkhoff, chairman of the worldsteel Economics Committee, said. “Combined with China’s slowdown, we also face low investment, financial market turbulence, and geopolitical conflicts in many developing regions.”

The only bright spot is that steel demand in developed countries is expected to show positive growth of 1.8 percent this year. The U.S. in particular should see demand increase by 2 percent in 2016, worldsteel predicts.

Realistic Expectations
While no one wanted the year to start off slow, most manufacturers aren’t too surprised. In a roundtable discussion with Metal Center News (MCN), Michael Bush, a vice president at Esmark, Inc., was quoted as saying that he didn’t expect the market to pick up until at least May. “Even though it will pick up in the second half, we expect 2016 to be down 1 percent for the year,” Bush told MCN. “That’s our general feeling going into the market.”

Bush isn’t alone. The American Metals Market annual survey of metals executives showed that 30 percent of respondents in the steel, aluminum, and other metals sectors expected business to be worse in 2016, and 70 percent predicted that the domestic economy would not fully turnout until 2017 or later. (You can read the full report here.)

The reality is that the U.S. is still in the middle of an economic recovery, which means that metal-cutting companies and other manufacturers won’t likely see any major growth this year. According to MAPI, manufacturing industrial production must grow another 3 percent in order to reach the pre-recession production level achieved in the fourth quarter of 2007, which means a full recovery is expected in the third quarter of 2017. Non-high-tech manufacturing production is 5 percent below the prerecession level and will not be fully recovered until the third quarter of 2018.

On a positive note, the latest numbers from the Institute for Supply Management (ISM) show some improvement. As reported by Plant Engineering, ISM’s monthly Purchasing Manufacturers’ Index (PMI) jumped 2.3 percentage points in March to 51.8 percent, putting the index solidly above the 50-percent growth threshold for the first time in 2016.

Out of 18 manufacturing industries, ISM says that 12 reported growth in March, including Fabricated Metal Products and Primary Metals. One survey respondent from the Primary Metals segment stated, “Our business is still going strong.” Another respondent from the Fabricated Metals Products segment said, “Capital equipment sales are steady.”

The big question, of course, is will this momentum continue? Analysts believe that continued growth will depend largely on continued strong employment because it creates new income growth and a solid base of consumer spending. MAPI says that another impetus is easy credit availability, which propels big-ticket spending for motor vehicles, residential housing, and nonresidential construction.

Moving Forward
While the overall data is certainly sobering, there are a few signs that suggest the metals sector can still snap out of the lull. As Modern Metals recently reported, “The average age of a vehicle on the road still exceeds 10 years; construction season is coming and Congress passed a long-term highway bill in December.”

Metal executives participating in MCN’s roundtable believe that automotive—which is predicted to top 17 million vehicles this year—will be the big market driver, as well as residential and nonresidential construction, white goods, and anything associated with “green energy.”

A report from Fabricating & Metalworking says that surviving 2016 will require manufacturers to use the current market conditions to their advantage. “U. S. manufacturers should be aggressive to take advantage of falling costs while at the same time finding new opportunities created by these economic forces,” the report says. Specifically, the article states that companies should consider employing two key strategies:

From an operations standpoint, continuous improvement activities will continue to be critical for industrial metal-cutting companies as they push through this slow period. Finding ways to optimize what is happening inside your shop doors is perhaps one of the most effective ways to balance the uncertainty of what is happening outside your doors. What does that look like? An eBook from the LENOX Institute of Technology’s lists five performance-boosting best practices that can help metal-cutting companies improve internal operations:

  1. Get lean. Although lean manufacturing is not a new movement, it is evolving. Companies that “got lean” years ago are focusing on continuous improvement, and a growing number of high-mix, low-volume operations are tweaking traditional lean methodologies to fit their specific situation. Regardless of your organization’s size, lean manufacturing should be at least part of your operational strategy.
  2. Invest in human capital. Industry data indicates that metal executives tend to invest in technology over people, but the tide is changing as the manufacturing industry deals with a serious shortage of skilled production workers. Managing this skills gap will require changing the way companies train and maintain talent, whether by beefing up training programs or rethinking their hiring tactics.
  3. Focus on quality as a process. There is no question that speed and agility are critical in today’s fast-paced market, but managers need to make sure that meeting demand doesn’t come at the expense of accuracy. To meet this challenge a growing number of market leaders are putting practices in place to ensure that their quality goals are met and maintained.
  4. Embrace preventative maintenance. In almost every manufacturing operation, machine breakdowns are one of the top causes of lost productivity. While some downtime is inevitable, proper maintenance and proactive care of equipment and tooling can reduce its occurrence. One benchmark survey revealed that 67 percent of industrial metal-cutting operations that follow all scheduled and planned maintenance on their machines also report an upward trending job completion rate.
  5. Form strategic supplier relationships. In today’s competitive marketplace, it is easy to base supplier relationships on price. However, a growing number of manufacturing leaders are placing more value on their supply chain. By leveraging the knowledge and services of trusted suppliers, companies can turn vendor relationships into strategic partnerships that have a real impact on the bottom line.

Ready and Waiting
All things considered, 2016 won’t likely be a banner year for industrial metal-cutting organizations. However, not all hope is lost. Recent upticks in manufacturing may indicate some positive (albeit slow) momentum, and many experts believe growth is in the long-term future, even if we have to wait another year. Until then, metal-cutting companies can continue to apply strategies that address external trends while also improving internal operations, putting them in the best position possible when the market finally turns around.

Why Ball and Roller Bearing Manufacturers Should Consider Taking a Gemba Walk

March 30, 2016 / , , , , , ,


Like every other high-production manufacturing segment, ball and roller bearing manufacturers have embraced lean manufacturing and the benefits it can bring. Some industry leaders like Timken have gone through total lean transformations, while others have opted to incorporate some simple lean tools or basic principles into their operation.

One lean manufacturing tool that continues to gain popularity among operations managers is “going to the Gemba” or taking a “Gemba walk.” This practical lean tool gives management a clear view of what is happening on the plant floor and, more importantly, reveals areas for possible improvement.

As explained in the eBook, Five Performance-Boosting Best Practices for your Industrial Metal-Cutting Organization, “Gemba” is the Japanese term for “actual place,” but has been redefined by lean thinkers as the place where value-creating work actually occurs. In a manufacturing environment, this is typically the shop floor. Many lean experts advise manufacturing executives to make time to visit this place—known as taking a “Gemba walk”—so they can see their operation from the front lines.

“Managers are not supposed to use this walk as a time to find fault or enforce policy, nor as a time to solve problems or make changes on the spot,” the eBook states. “Instead, a Gemba walk should be a time of observation and learning. Leadership should go on the walk with an open mind and welcome suggestions from operators and other shop floor employees.”

Why is a Gemba walk so important? A recent article from The Leadership Network provides three reasons why a regular Gemba walk is beneficial:

  1. First-hand knowledge is the highest form of information. A regular Gemba walk will give managers transparent and unmediated knowledge that is needed to challenge and validate assumptions made by data.
  2. Perspective is gained through experience. A regular Gemba walk allows managers to understand the challenges employees need to overcome on a daily basis to deliver the results that are being promised in the boardroom.
  3. Both people and process matter equally. A regular Gemba walk will help develop a culture that fixes the problems in a process and not one that blames the people performing the process.

In theory, a Gemba walk sounds fairly simple. Walking around and talking to operators seems pretty straightforward. However, there are a few tips managers should keep in mind before heading to the shop floor. IndustryWeek offers managers five suggestions to consider as they prepare for their Gemba walk:

Could a Gemba walk benefit your operation? To read more about this lean manufacturing tool, check out the slideshare presentation, Gemba 101, or this overview article from iSixSigma.

Small Optimization Opportunities for Your Machine Shop

March 20, 2016 / , , , , , , , , ,


Although the metalworking industry was hoping 2016 would be a year of growth, recent reports show continued declines in both new orders and production rates in February. While no one is worried that business is going to completely plummet, the sobering reality is that shops need to continue to focus on cost reduction and optimization to survive in today’s unpredictable and competitive market.

The challenge for many shops is figuring out where to optimize. After a few rough years, many shops have already implemented large-scale improvements to increase efficiency and save costs.  According to the results of Modern Machine Shop’s annual Top Shop Survey, 62 percent of leading machine shops (or “top shops”) have developed a formal continuous improvement program, and most use manufacturing tools like 5S workplace organization, cellular manufacturing, and value stream mapping.

What else, then, can possibly be improved? For some shops, the answer may be to “think small.” Take band sawing as an example. When thinking about optimization, the instinct for most operation managers is to focus on the efficiency of the saw, the workflow process, and maybe even the operator. But what about the tools? Could they be optimized?

If we are talking about band saw blades, the answer is yes. As explained in the LENOX Guide to Band Sawing, completing a proper break-in procedure on a new band saw blade will significantly increase its life (see photo). This not only allows the shop to cut more material, it also reduces unnecessary downtime to replace blades and lowers the cost of replacement blades.

When it comes to consumable tools like blades, many machine shops fail to understand the critical role they can play in the overall success of their sawing equipment and, ultimately, their entire operation.  In fact, according to a benchmark study of machine shops and other industrial metal-cutting companies, less than half (45%) of the organizations surveyed reported they “always” break in blades, 30 percent said they do it “most of the time,” and 15 percent said they do it “occasionally.” This means that the majority of industrial metal-cutting shops are missing out on a simple and effective opportunity for optimization.

This can be true of other “small” aspects of your cutting operations. As covered here in an earlier blog post, running blades at the right speed settings and proper lubrication can also directly affect your shop’s productivity, costs, and quality. Other metalworking operations, such as welding and punching, have similar best practices that offer opportunities for optimization, allowing you to get the most out of your manufacturing tools.

Like any change, optimization starts small. What areas of your shop’s operations are you overlooking?

Using Visual Devices to Improve Your Forging Operation

February 25, 2016 / , , , , , , , , ,


Workplace organization is one of those management principles that everyone knows is a good idea, yet it often falls by the wayside as managers focus on more pressing priorities like meeting deadlines and customer expectations. However, manufacturing experts continue to stress the importance of having a clean and organized manufacturing floor—not as a slap on the wrist, but because organizational tools are simple to implement and can offer a big return.

One tool that is often overlooked but can offer huge improvements is the use of visual devices. In fact, according to visual management expert and author Gwendolyn Galsworth, the visual workplace is one of the most misunderstood opportunities for a safer, more efficient, and reliable manufacturing operation.

“The entire world of work now strives to make work safer, simpler, more logical, reliable and linked, and less costly,” Galsworth writes in an article appearing in Fabricating & Metalworking. “Central to this is the visual workplace – not a brigade of buckets and brooms or posters and signs, but a compelling operational imperative, central to your shop’s war on waste and crucial to meeting daily performance goals, vastly reduced lead times, and dramatically improved quality.”

Specifically, Galsworth says in the article that managers should use visual cues to create a work environment that is self-ordering, self-explaining, self-regulating, and self-improving where what is supposed to happen actually does happen.

What does this look like? According to Galsworth, an effective visual workplace should follow some basic guidelines:

As an article from Modern Machine Shop explains, visual tools can include everything from different-color walkways marked for pedestrians and motorized vehicles, to foam cut-outs used as tool drawer organizers. One industrial metal-cutting company, featured here in a white paper, color-coded its blade stocking process. Each blade is marked with a colored tag, which corresponds to a chart that helps operators easily determine the right blade for the job. Stocking shelves are also color-coded, allowing operators to quickly locate and restock blades. This has improved operator efficiency, reduced the occurrence of operator blade selection errors, and prolonged overall blade life.

Visual tactics can also be used to improve safety. LENOX Tools, for example, has implemented a Safety Sticker program, which visually displays whether or not its operation has had any safety incidents. Sticker dispensing stations and a safety calendar are located at every entrance to the facility, and every employee is required to put on a green sticker with the number of days “accident free” written on it. When a recordable accident occurs, everyone in the facility changes from a green sticker to a red sticker for a seven-day period. After seven days, everyone reverts back to the green sticker. According to Matt Howell, senior manager, the program has been “a good rallying point for the facility and builds energy around safety.”

No matter what visual strategies you decide to institute in your forging operation, the goal is to use them to enhance communication and foster learning. The concept may seem a bit simplistic, but research shows it is effective. Studies by educational researchers suggest that approximately 83% of human learning occurs visually, with the remaining 17% occurring through the other senses. To put it another way: Your operators learn to work with their eyes first and their hands second.

What visual devices could you use to improve efficiency and safety at your forging operation?
