WELCOME"WHAT DRIVES US IS THE
CONVICTION THAT OUR
CUSTOMERS ALWAYS DESERVETHE BEST SOLUTION."

DEAR READERS,
2020 is an extraordinary year – the coronavirus pandemic has
overturned any previous economic forecast and poses major
challenges for companies around the world. We are not exempt
from this either.
Especially in times of crisis, the fundamentals of a company –the values with which we work and live – are decisive. We ourselves define the core values of what we do with precision andpassion. The precision of our machines, the passion with which
we develop, manufacture and continue to improve them, and theenthusiasm for further optimizing of what has been tried and tested –to achieve greater success.
This conviction continues to drive us, despite the adverse
circumstances, to pursue our strategic investment projects in our
three global manufacturing and assembly sites in the long term. You
can find out more in our cover story: "With passion and expertise".
Personal contact is the basis of good customer service – yet it
is increasingly difficult to maintain this under the given restrictions.
That’s why we’ve been working on solutions that we use to serve
our customers and provide them with service when you can't be onsite quickly. We present these solutions in the article "Magic word:
remote". They enable short-term support and a quick restart of production, even without personal contact. One thing that the crisis hastaught us: Agility and responsiveness are more important than ever.
With this in mind, I hope you enjoy reading the latest issue of"Motion"!

EXACTLY TO THE
MICROMETERTHE DRILL HAS A DIAMETER of half a millimeter,
its precision is in the range of a micrometer, that is: a thousandth of a millimeter.
Such minimal size ranges pose not only achallenge to production, but also to measuring. The optical measurement of thelengths, widths and angles of workpieces istechnically nothing more than the determination of gray-scale value transitions using
optics and cameras. For this, however, theoptical measuring system must read out thevarious gray-scales and the workpieces must
be optimally illuminated beforehand.
In order to prevent disturbing reflections
on high-reflective metals, a diffuser is used at
WALTER. This feeds the light from high-power LEDs into a plexiglass ring, avoiding reflections and creating detailed images. The
team at the Metrology Development Centerat WALTER in Garbsen (Germany) developed
the diffuser themselves. "We work withgreen light, because this makes the display
particularly high-contrast", explains Oliver
Wenke, Head of Metrology. The technology shown here is used as standard for the
WALTER HELICHECK PLUS and is optionallyavailable on HELICHECK PRO.

THE IMPORTANCE OF GOODEMPLOYEES is also demonstrated
by the UNITED GRINDING Groupby the sponsoring of the Swiss
Professional Championships Swiss
Skills. HR expert Maryame Sommer
explains what expectations the Grouphas in it.
What is the importance of Swiss Skills
for the group of companies?
It’s very important, because it emphasizes
the potential of vocational training andthe dual education system. It is an ideal
opportunity for those who want to orientate
themselves practically about the diversityof the professional world and supports

young people inrecognizing their po­
tential in professional life.
What do you expect from theinvolvement?
As employers of our size, we have a re­sponsibility towards young talent. With our
involvement, we want to make our commit­
ment to vocational training visible as wellas the promotion of future professionals.
Our average training rate is six percent,and this year we will be hiring apprentices
again. Professions such as grinding ma­chine operators or process technicians are
rarely found on the market, meaning that
we need to train people ourselves.

Is Swiss Skills only one form of
promotion of young talent?
It is a suitable platform for us to present
ourselves as an attractive employer for
apprentices. In the future, however, we
would also like to increase our presenceat training and further education eventsand thus strengthen our employer brand
UNITED GRINDING Group in the field ofvocational training.
The Swiss Skills Championships in theindividual sectors will also take placein 2020. Three apprentices from the

process of anew part

A LARGE, VERY BRIGHT, very clean production hall.
There is a distinct lack of the smell of warm
metal that is so common in mechanical engineering. Two men stand at a large machining
center in the front left wearing the obligatory
WALTER shirts while looking into the inside of
the machine and discussing matters. At therear right a slightly older staff member starts up
the test cycle on a measuring machine.
Mechanical manufacture lies at the heartof operations at the Czech site in Kuřim.
High-precision parts for grinding, eroding
and measuring machines are produced here.
The machine, on which machine operatorJiří Zeman and technician David Eliàšek areintensively discussing the machining of anew part, is one of two new universal 5-axis
machining centers.

Over 200 tools – from drills to cutters to theself-developed finishing tool – are locatedin the automatic tool changer of each of themachines. "It takes a few hours to produce aY-slide, and almost 50 of the tools are used,"
explains Petr Koneny, Head of Mechanical
Manufacturing. From here, the slide goesover to the measuring station, where it istested for precision in the range of thousandths of a millimeter. It is then installed ina WALTER HELITRONIC POWER 400 in theflow assembly.

THREE QUESTIONS TOERICH SCHMID
The Director Strategic Projects coordinates long-termalignment within operations"EVENING OUT WAVES…"
What is UNITED GRINDING Group's strategicalignment?
The economy in general and the demand for precision
machining systems in particular follow cycles. We
consider it our objective to even out these cycles. Thismeans we want to make our production as flexible aspossible with processing times that are as short as
possible, from receiving orders to delivering a machine.
Customers also benefit from this.
How do you aim to achieve such a level of flexible
production?
With our investments in high-tech machining centersfeaturing automatic equipment systems that permit agile
manufacturing at up to three levels, some of which do not
require human intervention.
What does that specifically mean for the company's
investments?
Our investment volumes roughly remain constant overtime. We once again base our actions on economic
cycles in this context. Anyone aiming to offer highprecision machines at a cutting-edge technical standard
needs to invest, regardless of whether we are affected byeconomic stagnation today or tomorrow.

introduced continuous flow assembly at
two of its production sites. In contrast
to the conventional tact assembly, themachines of different configurations“flow” in a continuous movement throughthe 18 assembly stations. In addition to there-organization of the actual production
this also required restructuring of
peripheral sections, such as the production
and warehousing logistics. The entire

and his team develop programming for processing new parts in the CAD/CAM system.
Although he is only 38 years old, the teamleader has been working in manufacturingfor 20 years, four of them at Walter s.r.o.
“As part of the machining of new parts weregularly come here to the shop floor to
analyze ways of further optimizing programming together with machine operators”, heexplains.
The industrial location of Kuřim and thenearby university town of Brno with its technical faculties are the ideal environment fora demanding machine manufacturer suchas the UNITED GRINDING Group. “We canrely on excellently trained staff members
here”, Milan Urban explains, “and that isjust as important as high-precision, highend machines.”
From mechanical production in Kuřim,the parts either go directly into assemblyor, until they are needed, into a storage
system with automated warehouse management. Small parts required for assembly
are stocked in an equally automated highbay warehouse located in an adjacent hall.
Logistics team member Petra Kupová andher colleagues prepare them for internal
supply as required. Throughout her 16 years
at Walter s.r.o. Petra Kupová has witnessed
all steps of the ongoing warehouse automation. Now, all logistics systems in Kuřim
– procurement, production, warehousing
and distribution – are optimized and merged
into a comprehensive project.
"Our next investment will be an extended warehouse management system", supply chain specialist Urban explains. It willcomprehensively illustrate the overall goods
flow and help to further cut processing
times as well as additionally boost delivery
reliability for our customers. º

EARLY DISCOVERY OF THE INNOVATIONSUMMIT
From the automotive manufacturer to thesoftware developer to the city of Hamburg:
Many are hosting Innovation Summits today.
However, the UNITED GRINDING Groupdiscovered the format of the “Innovation
Summit” very early on: As early as 2013,
Plüss, then Chief Technology Officer of
EWAG, initiated a Summit with the group’s
tool grinder manufacturers. The structure of
the two-day event proved so successful that
it was maintained when the Summits were
installed at the group level in 2018.
“On the first day, the heads of sales
report on trends and developments fromthe markets as well as the requirements ofcustomers. On the second day, workshops
will deepen the focus topics of thecompanies,” explains Christoph Plüss. In
five-minute pitches, so-called idea previews,
the speakers can present a project. CanMÄGERLE

in many cases one company benefits fromthe experience of another – and when theinsights are implemented, the customers
benefit above all.

IN THE SPIRIT OF DIGITAL SOLUTIONS
The first Innovation Summit 2018 wasdedicated to the UNITED GRINDING Digital
Solutions™. "Together, we have designed
a digital ecosystem and a corresponding
product roadmap for the entire group ofcompanies," says Plüss. "The two days were
exciting and highly informative and showedthat all brands had similar experiences
during the launch phase of the current
Digital Solutions," says Daniel Mavro, CTO
Surface & Profile.
The idea of group-wide interaction has
been an important element of the Innovation
Summits ever since. Those responsible
for the company step out of everyday
operational business - and into dialogue
with each other. A lot of information andsuggestions are exchanged in this way, and"AN INNOVATIONIS ONLY AN
INNOVATION IF IT CAN BE
PUT ON THE MARKET."
Christoph Plüss, Chief Technology Officer,
UNITED GRINDING GroupIn addition, the interaction and exchange ofideas also works vertically. "Of course, theShopfloor employees are also represented at
the Summits at the level of our company,"
explains Christian Dilger. "I then take theirsuggestions to a higher level for the Group
Summit."As a continuation of the first Innovation
Summit, the 2019 event focused more on
the fulfilment and implementation of thecollected ideas, rather than the generationof new ones. "In this process, it became so
precise that even the dates of the market
launch of various digitization packages werediscussed," says Plüss.

SUCCESSFULLY PUT ON THE MARKET
And, of course, the meetings aren’t justabout digital matters. “The idea of asynchronous tailstock was also presented,”
explains Huber. This runs synchronously to
the workhead spindle and ensures optimum
drive of the workpieces without a workpiece
driver. This increases process reliability andefficiency in equal measure. Pitched at thefirst Summit, the synchronous tailstock isalready in production. A good idea became
an efficiency-enhancing feature. Or as
Christoph Plüss puts it: “An innovation is
only an innovation if it can be successfullylaunched on the market, otherwise it willremain an invention.” ºMotion  01.2020

OFTEN IT IS ONLY SMALL OBSTACLES that cause
production to come to a halt. A backup battery, for example, which maintains the power
supply of a machine control system in theevent of a power failure, must be changed
from time to time. The machine operator
receives a notice on their operating panel ina timely manner. The production manager
has already seen this on their production
monitor and therefore has replacement batteries already in stock. The user manual andinstallation instructions are available to bothof them in the Customer Cockpit.
If you still need the help of UNITED

directly through the Digital Solutions app.
The service technician is connected live via
the Conference Center integrated in the

Brusatori grinds the drive shafts of its motors on a new generation
STUDER favorit and benefits from a more efficient grinding process

THREE QUESTIONS FORANTONIO BRUSATORIManaging Director of the family business,
Brusatori

The CNC universal cylindrical
grinding machine favorit 1600
for single and serial production oflong workpieces

BRUSATORI, based in Cuggiono near Milan,

specializes in the production of torque andservo motors. Since the beginning of 2019,
Brusatori has been grinding the bearing
seats of the drive shafts on a STUDER favoritwith a center distance of 1600 millimeters.
The external cylindrical grinding machine forthe entry-level segment is one of the firstmachines of the new generation to be delivered. With the STUDER favorit, Brusatori
was able to significantly increase its productivity. Loading takes place manually. Fora future digital connection, the machine isequipped with an OPC-UA interface.

HIGH ERGONOMICS
A machine bed made of Granitan® provides
the favorit with the legendary STUDER precision. The wheelhead can be positioned automatically every 3° and can accommodate
a belt-driven external and internal grinding
spindle respectively. The dresser position
can be manually adjusted in the T-slot.
Service doors at therear and on the right of the machine ensurehigh ergonomics.
Thanks to a machine base with integrated coolant tray and temperature control,
the machine reaches operating temperature
quickly. The automatic swiveling wheelhead
can be equipped with two tools. Geom­etry
clarifications are avoided by placing the
dressing spindle behind the workhead or
the tailstock.
For use at Brusatori, STUDER replaced
the standard face driver with the model ofan Italian manufacturer. ”Now the face driver is perfectly matched to the geometry of
our shafts. It allows the complete machining of the entire shaft in one clamping andguarantees maximum concentricity for all
diameters,” emphasizes Managing Director,
Antonio Brusatori.
CONTACT:
davide.santambrogio@studer.com

Why did you choose the STUDER
favorit with a center distance of1600 millimeters?
Other machines that came into contention were too large for our purposes, andthe favorit also uses the most modern
software.
What are the benefits of the machine?
The favorit is our first STUDER andworks much more efficiently than ourold machine. The significantly shorter
cycle times enabled us to increase ouroverall productivity. It grinds with muchhigher precision, allowing us to further
optimize the concentricity and tolerances of our shafts.
Can you pass on these benefits toyour customers?
Of course. The higher quality of the shafts
increases the service life of our motors,
and they run quieter. These are improvements that our customers really value.

Arcoprofil uses three
STUDER S33 to produce

THREE QUESTIONSFOR ROBERTO CASOLINManaging Director of Arcoprofil

HIGH PRODUCTIVITY
Arcoprofil relies on the new CNC universal cylindrical grinding
machine S33 from STUDER for shaft grinding

ARCOPROFIL, based in Santorso, North-East
Italy, specializes in the production of coldforged spline shafts for heavy-duty vehicles
and has been relying on STUDER cylindrical
grinding machines for 25 years. There are
currently three S33s in use, each of which
was put into operation at an interval of one
year. The newest, with a center distance of1600 millimeters and a synchronous tailstock, went into production in 2019. This
makes Arcoprofil one of the first users of thislatest generation machine. The spline shaft
specialists primarily use the STUDER S33
for the complete machining of transmission
shafts for tractors as well as flange, axle andfan shafts for agriculture and forestry.

Double T-slot and clamping surface for holding
dressing tool holders

What prompted you to purchaseanother S33?
For the machining of large shafts, we
needed a machine with the corresponding working envelope. The STUDER S41
with a center distance of 1600 millimeters
was “overqualified” for the task. When the
S33 was introduced to the market with acenter distance of 1600 millimeters, it was
clear: This is the machine for us.
What has improved with the new S33?
Thanks to the synchronous tailstock, theset-up time is close to zero. The cycle timeis 50 percent lower than with the older
STUDER machines and also compared tothe machines of the competitors.

DYNAMIC AND THERMALLY STABLE
The machine is based on STUDER’s T-slideconcept and features an extended strokeof the X-axis. An innovative machine basetemperature control ensures optimum dynamic and thermal stability of the machine.
The dresser sits on the double T-slot of thelongitudinal slide, which reduces the setup and realignment effort and therefore
increases the flexibility of the machine.

The 6C Tools Managing Directors Maximilian Warhanek
and Jens Boos (from left) have developed a strategy
for processing their tools with Dr. Claus Dold (2ndfrom left). Achim Schurius (l.), Sales Director Europe at
WALTER, tells us about further optimization possibilities

STRONGTRIO FORHARDNESS 10
The tool manufacturer 6C Tools, which specializes in micro tools made of extremely
hard cutting materials, benefits from the combined machining on grinding, eroding andlaser machines from WALTER and EWAG

IN THE WATCH INDUSTRY and medical technology, tools made of polycrystalline diamond(PCD) are becoming increasingly popular toprocess materials that are difficult to machine, such as glass or ceramics. Until a
few years ago, however, it was not possible
to economically produce the corresponding filigree tools with precisely machined
PCD cutting edges.

Warhanek. Lasers work without force andwear, can produce even the smallest details
with high precision and deliver smooth, error-free surfaces and edges.
The software used is decisive for successful laser processing. “Especially forspecial geometries, we are constantly improving machining cycles from operational
experience to optimize accuracy and speed,”says Warhanek.

EXTREMELY HARD CUTTING MATERIALSThis changed seven years ago when Maximilian Warhanek, now Managing Directorof 6C Tools, together with EWAG laser
specialist, Dr. Claus Dold and ETH Zurich,developed the first industrial strategy for
laser processing of complex geometries for
cutting tools made of ultra-hard materials.
This EU-funded project resulted in the laser
processing machines EWAG LASER LINEULTRA and LASER LINE PRECISION, aswell as 6C Tools AG in Zurich. It specializes
in the production of micro-drilling and milling tools with soldered PCD cutting blades.
”When manufacturing PCD tools withcomplex cutting geometries, thelaser can have clear advantages,” explains

COMBINED PROCESSING
In order to optimize the production of PCD
tools and shorten lead times, 6C Tools also invested in a HELITRONIC DIAMOND
EVOLUTION from WALTER. The machine,which works according to the “two-in-one
concept”, allows tools to be completely
eroded (PCD), to grind exclusively (carbide)or to combine both processes.
With the trio of combined tool eroding
and grinding machine HELITRONIC DIAMOND EVOLUTION from WALTER, laser
processing machine LASER LINE ULTRA
from EWAG and high-quality optical measuring machine HELICHECK PLUS, also
from WALTER, 6C Tools is ideally equipped
to produce microtools with PCD cuttingedges even in series of 500 tools and more
economically.

THREE QUESTIONSFOR JENS BOOS
Jens Boos,Managing Director of 6C Tools AG

What was the reason for founding
6C Tools?
Maximilian Warhanek and I founded
6C Tools in 2015 as a spin-off of the Chairof Machine Tools and Manufacturing
at ETH Zurich, because at that time we
discovered the great potential of lasers forthe production of micro-tools with PCD
cutting edges. Today we sell our highprecision micro tools to the high-techmarkets of Europe.
What does 6C Tools offer its customers?
On the one hand, we now manufacture
micro-tools for drilling and milling withfour employees. With their PCD cuttingedges, they are used for the efficient processing of components made of ceramics,
precious stones and glass. On the other
hand, we also develop application-specificsolutions for our customers in cooperation
with ETH institutes and inspire AG.
What role does the software play inlaser processing?
The software significantly influences
the processing results and continuously
develops with the experience gained
from practice. For special geometries, weconstantly optimize machining cycles,
therefore improving the precision andspeed of machining.

INTERNATIONALA COUNTRYIN TRANSITION
More and more companies are choosing Vietnam as theirlocation in Southeast Asia. This also opens up
new opportunities for the machine tool industry in the
country with 95 million inhabitants
TEXT: MATHIAS PEER

THE RAPID ECONOMIC CHANGE in Vietnam has
specifically been felt hard by the residents of
the island of Cat Hai. Just a few years ago,
their homeland was a long way away fromthe flow of goods in the global economy.
The existence of the inhabitants was based
mainly on fish farms and agriculture. Those
who had something to do in the neighboring metropolis of Haiphong depended on
the ferry boat, which stopped twice a dayon the island.
Solitude has been over since September
2017: After three years of construction, thefive-and-a-half kilometer long Tan Vu Lach
Huyen bridge opened – the longest sea
bridge in Southeast Asia that connects theonce sleepy island to the mainland. Just a
few months later, an international container terminal began operations on Cat Hai –North Vietnam's first port of call for large
container ships.
With the infrastructure came the industry: Since the middle of last year, production
by Vietnam’s first car manufacturer has been
up and running on the island. Under theVinfast brand, billionaire Pham Nhat Vuong
wants to produce a quarter of a million carsa year.

Cat Hai

The establishment of its own automotive
sector is a milestone in economic development for the country, which has a populationof around 100 million. After the end of theVietnam War and the victory of the Communists, Vietnam was one of the poorest
countries in Asia until the 1980s. The hardship forced the leadership of the Socialist
Republic to reform. The ensuing economic
opening initiated a historic upswing that continues to this day – even in the face of thecoronavirus crisis, economists in the country expect growth of up to five percent by
2020. While Vietnam has long been known
primarily for cheap textiles and footwear, it
is now increasingly establishing itself as a location for high-tech production and offeringmachine builders good sales opportunities.
Vu Trong Tai is one of the profiteers of
the trend. He heads the Vietnam branchof the Southeast Asian trade fair company
Reed Tradex and is responsible for the Metalex machine tool trade fair. Until the coronavirus crisis began, he was able to lookforward year after year to a growing numberof exhibitors and visitors. “The rapid industrial development is causing the demand formachine tools to rise sharply,” he says.

trade dispute between the US and China,
which disrupted global supply chains lastyear, has encouraged development. "Manycompanies have migrated from China to
Vietnam with their factories," he says. "Thishas helped the country to become the new
production center in Southeast Asia." In2020, manufacturing will continue to be themain driver of economic growth, which lastyear was more than seven percent, exceeding the government's expectations.
The massive rush of foreign companies was one of the main reasons for the
economic boom: 3,880 projects received
investment licenses last year, an increase of
28 percent. The total volume of announced
foreign direct investment also rose sharply,
growing by seven percent to 38 billion dollars. Two-thirds of the capital that went toVietnam went to the manufacturing sector.
With new factories in Vietnam, many companies tried to escape the punitive tariffs
imposed on each other by China and the US.

GLOBALIZATION AS AN OPPORTUNITY
The country is considered as an ideal alternative location: The population is young
and comparatively well educated. And thegovernment sees globalization as a great
opportunity for the country and has signed
a number of free trade agreements: With
the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP),
Vietnam has been in a free trade area withcountries such as Japan, Canada, and Mexico since 2018. At the end of June 2020, Vietnam signed a free trade agreement with the
EU that abolishes 99 percent of reciprocal
tariffs. The RCEP trade pact, which includes
Vietnam and its Southeast Asian neighbours,
is also due to be completed in 2020.

The good conditions particularly attracted
electronics manufacturers: Nintendo announced that it would move part of its game
console production to Vietnam. Sharp relieson the site for its production of LCD displays
for the US market. And the Apple supplier,
Goertek, also opted for another mainstay in
the Southeast Asian state.
Vietnam was also able to convince otherindustries: In May 2019, the automotive andmechanical engineering supplier, Schaeffler,
opened a 45 million euro plant in the South
Vietnamese industrial city of Bien Hoa, withthe declared goal of becoming more independent from China. The supplier ZF Friedrichshafen built a factory for chassis module
technology right next to the Vinfast factoryon the Cat Hai island. The Chinese engineering company, Omnidex, also moved part ofits production to the neighboring country.

STUDERSCHAUDT“Vietnam has established itself as an important component of international supply
chains,” says the Association of German
Machine Tool Manufacturers (VDW). In order to be competitive on the world market,
manufacturers are dependent on sophisticated production technology. However, themachine tool industry in Vietnam itself is only
slightly developed, according to an analysis
by the association. The German foreign tradedevelopment agency GTAI also observes apent-up demand: “In order to increase theirproductivity, Vietnamese companies need
new or at least modernized equipment,” said

GREAT SCOPE FOR GROWTH
The situation of Vietnamese machine toolbuilders has changed little since then. “It isa great challenge for local manufacturers tokeep up-to-date with modern technologies,
in order to be able to compete,” says industry expert, Vu Trong Tai. Currently, Vietnam’s
economy primarily relies on machine imports
from abroad. In the first nine months of lastyear, they had a total value of 26.9 billion

dollars – 12 percent more than in the same
period last year. Imports come from Europe,
America, Japan and South Korea – but above
all from China, which last accounted for almost 40 percent of machine deliveries.
Chinese machine builders still have astrong advantage over Vietnamese ones,
Tai finds. This is due to the fact that Chinese manufacturers can rely on industrial
supply chains that are significantly better
developed. Vietnam is also lagging behindin terms of infrastructure. Tai, however, isconvinced that this will soon change. The
government is working to improve the conditions, he says. Import restrictions adopted
last year could also help local manufacturers: For example, used machinery older thanten years may no longer be imported into
the country. "The time has come for foreign
manufacturers to increasingly engage withproduction in Vietnam," Tai says. He is optimistic: "There is great scope for growth." ºAuthor Mathias Peer reports as a world

According to Puschmann, this perspective
results from three developments. On the
one hand, from the interim upswing in theautomotive market, initiated by international
and Vietnamese suppliers: Not only global
players such as Bosch or Schaeffler are activein the country, Vinfast also produces cars ofa Vietnamese brand. Secondly, Puschmannalso observes that Vietnam benefits fromthe trade dispute between China and the
US. Thirdly, due to the different wage levels,
there is a shift in production from Taiwan and
Korea to Vietnam. According to Puschmann,
there will be an upgrade from low-cost to
premium grinding machines in the area ofcontract manufacturing. Here, too, there areopportunities for manufacturers such as the

ARTIFICIAL INTELLIGENCE (AI) IS DESIGNED TOSUPPORT HUMANS. In fact, it can do one thing
above all: control. AI controls what advertising we see on the internet, controls autonomous robots for rescue and recovery, controls self-driving cars. In view of the global
climate problem, however, there is a growing
question about the impact of this support on
our environment.
The last key digital technology that haschanged our daily lives has become an integral part of our energy balance: Every single
one of the 3.5 billion searches per day consumes 0.3 watt hours, according to Google.
That's a gigawatt hour in total – as much as
50,000 households consume every day. And
what about the power consumption of AI
systems? Of course, anyone who does superhuman work will also have to be allowed
to use superhuman energy. But how much
more can it be?
Well-known representatives of such
AI systems are IBM's Watson and Google
DeepMinds AlphaGo. Watson won the TV
quiz "Jeopardy!" and has declassified theformer winner of the game. AlphaGO defeated one of the world's best players in the

board game Go. In both cases, artificial intelligence stands out from humans – at leastin terms of the implementation of clearly
defined rules of the game. If you ask about
the energy consumed, AI systems perform
worse: The hardware used suggests thatthe power consumption of both systems isabout 100,000 watts. Compared to this, thepower consumption of the human brain is afive thousandth.
This is no difference for current AI systems. At the largest annual computer linguistics conference in 2019, results were
presented showing that learning natural
language using the most advanced AI methods takes more than 0.5 gigawatt hours at
the moment. If the later application of thelearned language model is calculated, itcomes to about 10 kilowatt hours for learning; the same that is extracted for a Tesla
Model 3 or a VW ID.3 from the charging
cable in an hour.

AUTONOMOUS VEHICLES
Most of the energy is consumed by special
hardware (GPUs) needed to learn and apply a learned AI system. In particular, theenergy consumption of the application of awell-learned AI can become a major problem
in the coming years. This is due to the frequency of the application. The learning takes
place once, even if gigawatts are consumed,
after which the system has “learned” it and it
can be copied and applied millions of times.
For example, this is the case of fully autonomous vehicles. There, the AI system is continuously active, evaluates information andmakes decisions. Prototypes consume up to
2.5 kilowatts per hour. Admittedly, energy

consumption is not currently the bigest problem of autonomous mobility. But it should
be clear that such a high demand for performance is far from any practicality, especiallyat a time when we are trying to substitutefossil fuels and maximize the efficiency of
our vehicles.
When discussing the level of energy requirements of current AI systems or theirpracticality, it must be made clear: Apartfrom Watson, all of the systems mentioned
so far have been research prototypes. They
were not brought to series production
and were often only used a few times under semi-real conditions. Of course, many
AI systems are already in use in businessand industry, but these are well-researchedmethods, some of which have been studied
for decades, and not techniques that havejust been used for the first time.

Thinking about what
is just around the corner: With "Jeopardy"
you have to find theright questions forgiven answers. IBM's
Watson has beaten its
human opponents

pendently, we must first understand what
resources the various AI methods needand how to reduce consumption, if necessary. Otherwise, the energy consumption
is simply too high to be integrated into themobile device.
A recent study by Microsoft called "ZeroRedundacy Optimizer" shows how skillful resource utilization (specifically, efficient use of
GPU memory) can reduce the required GPUs
and therefore the energy required to learn
many AI models to a quarter. Researchers
at TU Dortmund have already gone one stepfurther in 2018.

It showed that calculations that are fundamental to learning and applying AI systems
can also be performed on micro-computers,
so-called ultra-low-power (ULP) devices.
Such ULP devices only consume a few milliwatts, some of which are sufficient for operation with a small solar panel. In this way,
future AI systems could be used completely
energy-neutrally and instead of doing what
it was originally intended to do in the basements of the data centers in the smart home,
in intelligent delivery drones or householdrobots, they could do what it was originallyintended for: to support humans. º
