Automation or automatic control, is the use of various control systems for operating equipment such as machinery, processes in factories, steering and stabilization of ships, aircraft and other applications with minimal or reduced human intervention.

Meggitt Robotic Drilling Workcell

Meggitt Polymers & Composites recently updated their manufacturing operations by installing a Drill and Cutting workcell, designed and integrated by Concept Systems. The fully automated workcell uses a Fanuc M-710 series robotic arm and state of the art end of arm tooling to drill and cut material for the aerospace industry. The goal of this project was to improve accuracy and throughput of thousands of parts, allowing Meggitt Polymers & Composites to meet the needs of their customers.

Project duration: 4 months

Team:
Client: 1
Concept Systems: 4

Concept Systems’ time on site: 2 weeks

Headquartered in the United Kingdom, Meggitt PLC is an international group employing some 8,000 people specializing in aerospace equipment, high performance sensors, defense training and combat systems. Meggitt Polymers & Composites, in McMinnville, OR focuses on delivering gaskets and seals to rigorous standards to be used by some of the world’s leading manufacturers.

Meggitt Polymers & Composites had an opportunity to expand their business with a current client, but to do so, they would have to increase production by means other than human labor. Historically, the work on these parts was being done manually in a labor intensive manner. Production rates were limited to an average of 1000 parts per year, but needed to increase production by 300%, or 3000 parts per year, to meet demand. In addition to throughput, accuracy and safety were of high concern.

“A lot of these operations were being done by hand, and we were missing holes,” James Robertson, Meggitt’s vice president of operations, said in a recent news article featuring the project. “This enabled us to simplify the process and improve our quality.”

Concept Systems kicked off the project by meeting with the project manager at Meggitt, to first understand their operations, concerns and goals, ensuring the right solution was delivered based on measurable results and a favorable return on investment.  Once the objectives, timelines, and goals were established, Concept moved forward with the design of the workcell.

The system that Concept created for the drill and cutting project is a fully automated workcell featuring a Fanuc M-710 Robot. The workcell boasts an integrated tool changer that provides seamless interchange of tools, allowing continuous production of the desired hole shape and size for 8 different parts. Further, Concept designed end-of-arm tooling to accommodate 14 automated, interchangeable options for drilling and cutting.  To support flexibility of the workcell, Concept also designed and provided fixture racks to accommodate 8 different parts. All of this was under the direction of a thorough risk assessment based on ANSI/RIA R1506-2012: safety first design of the workcell and all components.

Technology used in workcell:

  • Fanuc M-710iC Series Robot
  • ServoRobot Tool Changer
  • PushCorp High Torque Servo Toolholder
  • Tool Changing Station
  • 4 Custom Built Part Fixtures
  • Safety Interlocked System Guarding: Light Curtain, Area Scanner, Dust Hood

The workcell has now been in production for over 6 months and the initial results show that the project was a success. Meggitt has expanded their production capacity to 3000 parts per year – a 300% increase as per the project goal. Meggitt has also achieved high precision and repeatability from the robot and tools which significantly reduced rework and product loss. Last, the physical guard fencing, door interlocks, and area scanners provide the latest in worker protection.

Preventing Extensive Downtime From Equipment Failure

When updating or maintaining older equipment, it’s important to have maximum visibility into plant operations and make every investment dollar count.

As a company that specializes in automation controls, we field a lot of different requests from clients who want a quick budgetary quote to retrofit an older piece of equipment. These requests usually come in after a piece of machinery has failed and the company has encountered one of three scenarios: 1) The company doesn’t have any documentation. 2) The last person to work on this machine has retired, and no one has been trained. 3) Replacement parts have finally become too difficult to find, even on eBay. There are other reasons, of course, but most often a client is responding to some situation that has left the company exposed to a much larger downtime risk than previously thought.

I want to discuss two different prevention techniques in hopes of providing some insight for companies to consider as they wrestle with keeping equipment current—and we all do! First, don’t be caught off guard with not knowing how and when a piece of equipment is likely to fail. There are several software options available today that provide performance data and maintenance scheduling, helping companies avoid unplanned downtime. Second, consider a machine retrofit as a way of preparing for tomorrow’s manufacturing instead of just reacting to a problem with a rush to update the machine.

Software solutions for machine monitoring have come a long way in the past five years. I don’t know if it can be considered a “mature” market, but there are many established providers that have proven their solutions. Conveniently for users, there are several options available from complete software platforms that monitor everything from CNCs, robots, PLCs and test stands to simple offerings that are designed to provide real-time monitoring per single device. Regardless of your specific needs, be assured that you have options that can be found with some basic Google searching. To make matters easier, a lot of these software providers offer their solutions via a software-as-a-service (SaaS) model, which reduces the risk of overcommitting and lowers upfront costs.

All this to say that it is wise to seriously consider employing a machine monitoring software tool of some sort sooner rather than later. The advantages of doing so far outweigh the risk. Consider some of the benefits: scheduled maintenance events based on known wear, use or observed conditions; dashboard monitoring and/or reporting available via desktop computer or mobile devices; uptime and throughput reports to monitor trends; and automated alarming provides alerts that will send alert condition messages to supervisory personnel to facilitate an immediate response. With so many software solutions available provided as flexible options like SaaS, it is a good time to develop and implement a strategy that takes the guessing out of machine monitoring.

The second key aspect to keep in mind when maintaining or updating older equipment is when you evaluate a retrofit investment, consider what you can do to make that piece of machinery or that production line ready for the Industrial Internet of Things (IIoT). In the not so distant future, experts predict whole manufacturing floors will be populated by intelligent machines that are able to monitor themselves, schedule their own maintenance and provide constant monitoring. This future state will allow machines to interoperate and create dramatic efficiencies not possible today. Machines will do this by dynamically adjusting to manufacturing conditions to ensure maximum efficiency. Although all of what is predicted is very exciting, we won’t get there overnight. The clear majority of manufacturers will use a phased approach to slowly migrate equipment to Industry 4.0 requirements over the next decade, since very few companies have the luxury of starting their production strategies from scratch.

Companies can prepare for the future by utilizing their automation roadmap, or 3- to 5-year manufacturing plan, to ensure that any investment made in a machine retrofit will not only be applicable in the future, but will also be an advantage as they phase in more Industry 4.0 equipment. Learn why an automation roadmap is essential to remaining competitive. Not sure how to get started? Learn how to get started on an automation roadmap.

There are several software options available today that provide performance data and maintenance scheduling, helping companies avoid unplanned downtime.

Here are some important things to consider with a retrofit: network compatibility, whether wired or wireless; security protocols to ensure all data is protected; virtualization (consider server consolidation and thin client architecture); and an interface that provides operators and decision-makers with valuable information to make appropriate, timely decisions.

In today’s world, the information coming at us is unlimited and it can feel like we are constantly reacting to issues and scenarios. When updating or maintaining older equipment, it is crucial that we take a proactive approach. To do this, ensure you have maximum visibility into plant operations as described above and make every investment dollar count when you retrofit equipment to be fully prepared for tomorrow’s manufacturing.

As a final comment, integrators certified by the Control System Integrators Association (CSIA) can be an invaluable resource whether you are considering manufacturing software or creating an automation roadmap. Often, integrators have worked in a vast range of manufacturing scenarios and they can leverage that knowledge to the benefit of the client.

Why Automation is Good for the Economy

When science fiction writers started to predict that robots would someday take over many of the jobs that human workers do, they probably didn’t realize that the time would come so quickly. In the last 10 years, engineers and computer scientists have made rapid advances in the design and production of robots. Computers and robots are everywhere, but especially in the manufacturing industry. Automation will certainly change the way people do work, but that doesn’t mean that the overall number of jobs will decrease or that the economy will suffer. We can tell you about some of the ways that automation will increase jobs and the overall growth of the economy.

The Saved and Re-Invested Company Money

If a manufacturer invests in automation, it can save the business money and create jobs for people who assemble, design, and maintain the automated machines. There’s always the risk that the jobs that have become automated will be lost, but when companies have more money, they can hire in other areas, increase their existing employees’ wages, or start new off-shoot companies. This creates more money flowing through the economy and provides opportunities.

The Nature of Technological Advancement

In terms of the people creating and maintaining the machines, their skills will be highly valued. More people will study engineering and robotics, and skilled jobs will steadily grow in demand. Even what could be considered unskilled jobs, or assembly of machines or routine maintenance, will need to be completed by humans. Over the course of history, humans and machines have always worked in tandem. When the first stone chisel was invented, it took fewer people and less work to cut things, but it created a whole new field of possibilities for what humans could do with the saved time and energy. If you think about the evolution of technology as this type of progress, saved and redistributed effort, then robots are just the next phase and the economy will continue to adapt and flourish as a result. Economies adapt to these types of shifts in each age, and preventing innovation isn’t really an option anyway.

Staying Competitive

The fact is, automation has been proven to save companies resources, so eventually any company that wants to be competitive is going to invest in it. If a country wants to stay at the top of their respective field, they’ll invest in this convenient and cutting-edge technology. Automation will not only create new types of jobs and increase liquid revenue in the economy, it will also pave the way for even more advances in the future that will be the foundation of economies then.

Creating a Foolproof Automation System for Your Business

In an age with increasing costs and additional demands, finding a way to automate some business processes using technology may be the key to solving problems. At Concept Systems, our engineers are problem solvers who use the latest in technology to create foolproof automation systems for businesses.

There are 2 primary reasons businesses choose to automate some or all of their processes whether those processes are related to production or fulfillment. First, manual processes are costly, and employee skills can be better allocated if the repetitive tasks are done by machinery. Already, engineers are hard at work designing robotic controllers that can grind and brew coffee to order and machines that can be used to eliminate weeds without the use of herbicides on corporate farms.

Second, automation increases production. Automating a manufacturing operation typically means increased production rates and labor productivity. In the simplest terms, business owners get more output per labor hour.

So how do Concept Systems engineers hammer out a robotic vision and controller for a specific industry or organization?

We start with a problem. When we kick-off a project, we spend time getting to know the full scope of a project and the necessary elements for success. The proposal to solving your problem will include the cost and a schedule. Fully understanding the problem and developing ideas for an automated solution or upgrade to your existing processes requires a bit of time as we determine what your system will do and how it will work. Our engineers work with key players in your company to draft on paper an elegant system including materials, electrical schematics and software.

For example, for a coffee roasting company, we upgraded a robot that was designed to unload pallets full of raw coffee beans and place the bags on a conveyor belt to send to the roaster. The robot’s vice grips, however, were a problem and often tore bags and spilled beans.

A Concept System team met with company stakeholders to design pneumatically-operated tines that eliminated tearing as well as a control system with 3D vision and advanced software to precisely position bags on the pallet.

Once a company approves a design, Concept Systems engineers get to work creating software and hardware to alleviate or solve the problem. This phase of development involves procuring materials, assembling the project, and testing.

During the final phase of development, engineers work closely with vendors at the factory or operation site to ensure proper installation of equipment and to train personnel to support and maintain the automated system.

Automation and robotics are the wave of the future. With specially engineered tools and resources, a team of engineers can create a foolproof automation system for your business and move your company into the future today. Contact us today to get started!

Collision Avoidance Moves into More Dynamic Automation Environments

Manufacturing environments are busy places with multiple machines, bustling workers and numerous machine-human interactions. Avoiding collisions between robots and humans is a high priority. Some solutions require a multilayered approach, integrating a variety of technologies, to create a reliable system. As more manufacturers add robots, there’s an increased interest in ensuring they work safely with each other and with humans.

Leveraging techniques from stacker cranes
Companies that increase their use of robotic automation can learn from collision avoidance techniques used with cranes, which received early attention because a collision with equipment in the work environment or the component itself was unacceptable. This posed a serious safety hazard that could cost thousands of dollars in lost production time and rework or scrap. By using 3D vision and industrial computers, collisions are now largely avoidable.
As technologies advance, dramatic system improvements are possible. That was the case with Boeing, which found its floor-based registration system for painting planes no longer provided the accuracy it needed. As a long-time partner to Boeing, Concept Systems Inc. stepped in to assist the aircraft manufacturer in addressing this issue by deploying a new collision avoidance system.

A key component of the new system adopted by Boeing in one of its paint hangers was the proximity query package (PQP), which can detect imminent collisions between two computer-generated objects. Information about the exact size and shape of the plane is exported from Boeing’s design software and then rendered as a 3D graphic in OpenGL, a widely accepted open graphics standard. It similarly renders the stacker platforms for validation and troubleshooting the system. Continue Reading →

Reflection Can Reveal Best Practices

SamJerry
This is an exciting time to be in the automation business, as there are tremendous opportunities to integrate technologies and revolutionize the production of goods. Reflecting on your processes can help make the most of them.

As the year comes to a close, it’s not uncommon to reflect over the past year. We recently had an opportunity to do just that, but in a very thorough way, by completing an application for a national award. The process was both inspirational and educational. I found myself reflecting on how we do business and realized that we are using many best practices that I want to share with you.

Hire the best and brightest.
We have an exceptionally smart team that thrives on learning new technologies and jumps at the chance to do work other companies either can’t or won’t do. We encourage employees to provide suggestions and feedback, especially if it would enhance or encourage continuous improvement. We challenge our engineers to stay on top of emerging technologies and to work with different industries.
