Ligna 2015 in Hannover, Germany is coming up in May and many of us will be visiting this most important equipment tradeshow for the woodworking industry. There is a new buzz going around in the European manufacturing industry; not just the woodworking industry. The term Industry 4.0 was

used for the first time at the Hannover Messe show in 2011 and originates from the high-tech strategy of the German government which promotes computerization, to a much larger scale than is currently used, in the manufacturing industry.

We have had three industrial revolutions in the past. The invention of the steam powered engine lead to the first Industrial Revolution. With the implementation of electrical power and assembly lines at the beginning of the 20th century, the second Industrial Revolution brought us mass production. This was followed by the digital revolution, the use of electronics, IT, and robots to further automate production. And now leading edge technology is yet again entering a drastic change. This Fourth Industrial Revolution is fueled by the need to regain manufacturing share lost to low-wage-cost regions in Asia and South America. Europe, and particularly Germany, is driving the development in a unique combination of industry and government funding.

This Fourth Industrial Revolution is already underway and experts are talking about a fast and disruptive change for most, while some industries like the woodworking industry might have a more of an evolutionary change. Only one thing is certain; this major change will come and there is no going back! It is projected that the physical environment will be seamlessly integrated with the information network. The internet is combining processes, systems and intelligent machines to form a sophisticated network. The publications refer to the Internet of Things (IoT) and the Internet of Services (IoS).

From here on the concept/theory becomes complicated! With all the publications in print and on the internet you will find it difficult to get a simple explanation of the subject. At the recent German ZOW tradeshow in February, an important meeting place for the suppliers (hardware, board material, lacquer, prefabricated parts, services…) to the industry, some solutions where shown. Suppliers showed partial solutions and elements like RFID’s and software, however the overall vision and plan has not been presented yet.

In a revolutionary change, current rules often no longer apply. Changes are fast and can be disruptive and even destructive. If you briefly look into other industries, companies like Google or Apple have completely changed the game in the music and communication/phone industries, and we expect further changes in the entertainment/TV industry, as well as the automotive industry. We are just at the beginning of this (r)evolution. So once change gains traction with at least one company, the rules of the game could change quickly.

So where are we now? Companies are implementing more and more sophisticated manufacturing software. The best in class processes their customer orders seamlessly to purchase orders and manufacturing orders. With a few clicks, automatically prepared Purchase Orders are released to suppliers and Production Orders are passed on the shop floor providing information in suitable machine language to retrieve material and place it at/in the machine. The required cutting plan, nesting plans or other CNC programs are almost instantly available for machines. Suitable work instructions, printed or on screen, interface with the operator. Barcodes or RFID’s allow the software to collect feedback from the shop floor to update the software regarding the production process.

This is still considered “Third Industrial Revolution”! And to be quite direct - a large number of North American companies have not yet mastered this level of sophistication. What is next is building on the changes brought by the 3rd Industrial Revolution. In order to enter the new technology you first need to build strong foundations by implementing the above technology properly.

In the near future the machines communicate with each other. The work pieces talk to the machine and the system talks to the vendors. For example, if a customer delays an order (or wants to expedite the delivery) the system would optimize according the new situation. It would check the availability of all required materials and parts, including the suppliers systems. It would sideline current production orders to allow the now more urgent priorities to be manufactured first. If the optimization recognizes sufficient un-used machine capacity it might advance an upcoming maintenance and service call on the machine, but not until the service technician and the required spare parts are confirmed. The system would then inform the worker or the management what the recommended course of action is.

Is this Utopia? Not anymore. The manufacturing industry is moving towards this competence.

Can we wait until this trend passes and life returns to normal? Let me answer the question with a question: Could your business survive if you didn’t invest in the technology brought by the 3rd Industrial Revolution (computers, software, CNC machines…)? The answer to both questions is NO! If we know we need to address Industry 4.0, the next question is how quickly we need to act? This depends on many factors. Are you currently in a comfortable position with no market pressures? Do your competitors have no interest in modernizing their plants? Do you foresee little or no competition from Europe, South America or Asia? Well, in that case you, have lots of time! But that would be the real utopia. We all need to start addressing this subject. This does not mean you need to stop buying machines and you need to “buy Industry 4.0”. First of all, you cannot buy a “plug and play” version which would fit your factory - you need to build it yourself!

You also need to complete your transition through the 3rd revolution.

Picture it this way; you are not setting a new goal; your measurement bar has just gotten raised by a huge amount.

If you are interested in pursuing this journey, a good start is a “fitness review”. How close are you in managing the “batch size of one”? Lignum Consulting has identified 7 key areas which include all aspects of the business, that all need to be addressed simultaneously in order to get your company ready.

Strategy - Does your market accept mass produced product with little variations or does the market demand high variety in short delivery?

Product - Are products complex and are variations the exceptions, or is there practically no difference between standard and special orders?

Technology - Are you producing into Finished Goods warehouse to ensure short lead times, or do you have flexible manufacturing to allow order specific production?

Logistics - Is the material supply to assembly and shipping inconsistent, or does the organizations currently ensuring consistent high levels of performance?

Data integration - Standard product has BOM’s, but do special orders need to be created manually? If product does not arrive in the buffer on time, do we need to look for it, or there is sufficient monitoring to ensure effective controls?

Organization - Are machines repaired only when broken, or is systematic preventive and predictive maintenance fully implemented?

Human Resources - Do employees stay on the same workplace for a long time, or is systematic cross training implemented?

As you answer these questions a more realistic picture will emerge. It will show where the company needs to improve in order to achieve the batch size one capability, which will be prerequisite in most cases.

There are six design principles to follow when implementing Industry 4.0, or the “Smart Factory”, as it is referred to in US publications:

Interoperability: In the future, equipment, software tools, work pieces, and humans are networked and will communicate with each other. Standard communication protocols are essential.

Virtualization: The manufacturing processes (physical world) is replicated and linked to virtual models and simulations.

Decentralization: This technology allows localized decision making for routine tasks. Only critical issues like machine failure are delegated to higher levels.

Real-time Capability: This technology allows the plant to immediately react to equipment failure and re-route the remaining production orders

Service Orientation: All services of companies, systems and employees, are reflected and stored on the internet and can, if needed, be used internally and externally.

Modularity: Modular systems are able to easily adapt to changing requirements. In the Smart Factory modules can be added or changed using the Plug & Play principle.

What does it mean for us now?

The dividing lines between the internet, the machines, the software, the tools and the work piece will start to disappear. Everything will become a piece of the other, like switching your lights on from your smartphone.

Before you visit the Ligna show, start the discussion in your company; IT, Manufacturing Engineering and Production need to learn the basics of Industry 4.0 and synchronize their approach on this subject. At this time, no company is ready for this change. Industry 4.0 is too new. But if you do not start the discussion now, or if you don’t do your fitness test and if you don’t read up on the internet, you miss the opportunity to ask the right questions when you get to the show.

When you visit the show you don’t just look at machines; you need to start to imagine and understand the virtual world connected to it. This year the Ligna show management together with Lignum Consulting offers a series of guided tours to the subject of Automation /Industry 4.0. The tour will take approximately two hours visiting participating exhibitors for 15 to 20 minute presentations each. Taking these tours gives you a quick and efficient introduction to this subject. For more info please visit: http://www.ligna.de/en/tours or www.lignum-consulting.com.

Your short term objective should be to compile a strategic plan; your company specific Industry 4.0 vision. This time phased plan should outline your milestones, your approach, and your resources to do it. If you do not plan for it will not happen.

We hope to see you at Ligna 2015 in Hannover!
