Dontyne Systems

A Message from Lord Pickles and Lord Blunkett, followed by Dontyne Systems's best practice article

The ability to listen and learn from one another has always been vital in parliament, in business and in most aspects of daily life. But at this particular moment in time, as national and global events continue to reiterate, it is uncommonly crucial that we forge new channels of communication and reinforce existing ones. The following article from Dontyne Systems is an attempt to do just that. We would welcome your thoughts on this or any other Parliamentary Review article.

Dontyne works with partners
such as Renishaw plc and Mazak
Inc to demonstrate integration of
design and production data for
more efficient and accurate gear
production at Gear Expo 2017 Dontyne applies Industry 4.0 principles to rejuvenate ancient
technology. In 2006, Dontyne Systems created the Gear
Production Suite software program to provide a platform
for integrating design and manufacturing processes for more
efficient production. The export and import of data to machine
tools and measuring devices was essential to reduce potential
errors. Dontyne Gears was formed by DrMike Fish in 2013 to
address a requirement in the gear industry to facilitate small
testing programs for large and small specialist companies. This
would utilise all modern techniques for both CAD and production
equipment as well as provide a testing program if necessary.
The principles of gearing have been well understood for thousands of years and
it is therefore easy to assume, even by companies involved in mechanical power
transmission, that there is nowhere left to go with this technology. Gear and
gearbox manufacturers are under a lot of pressure to meet stringent demands
in gear quality, efficiency and conformance to exacting design standards.
Fortunately,we are at a crucial time in the industry when technology can permit a
step change in capability to improve product and performance.
New CAD and CAM technology can produce beneficial tooth forms to reduce
gear box size with consequential reductions in machine time and transport
costs. Research has shown it is possible to get dramatic improvement in power
density, meaning the same power with a smaller unit or more power through the
same-size unit, with obvious benefits in savings for company resources and the
environment. Dontyne can design, analyse, and prove new gear forms prior to

50 per cent better power density than
In 2006, Dr Mike Fish and Dr David
Palmer set out to develop and globally
market intuitively designed, user-
friendly gear software with a heavy
focus on making it easier for design
and production to communicate. This
was started from offices in Newcastle
upon Tyne and Melbourne, Australia.
The concept was to not only provide
recognised standards to reduce
calculation time but also to model
machining processes at the design stage
to allow engineers to investigate the
effects of tooling selection and machine
methods on performance and to identify
likely faults before productionbegins.
The information can be returned to the
design parameters for more efficient
production. There is now a convenient
term for this called Industry 4.0. The
resulting Gear Production Suite (GPS)
software now has over 150 installations
in 15 countries with UK, Japan and USA
the biggest markets, and has an annual
turnover of around £0.75million.
Dontyne has benefited from the internet
and high-speed data flow, which
support the software from our offices,
thereby improving support and reducing
costs for us and the customer. This
was all achieved with six personnel and,
given that there is a $36billion annual
turnover in the gear industry, there is a
great deal yet to tap into. It is interesting
to note that Europe was found to be
the most difficult market to break into
Dontyne’s plans for development will
not be greatly affected in the short or
medium term by the Brexit process.
Gearbox Model calculates deflections
in housing, shafts and components
such that detailed analysis of each
tooth contact can be made for noise
and vibration, stress, and efficiency.
Detailed macro and micro geometry
can be established for each gear pair,
and analysis of surfaces under load can
be made for transmission error, stress,
and efficiency to determine optimum
form before moving to manufacture.
Tool designs can be produced for
various process and manufacturing
simulations carried out to validate the
form, including macro geometry, are
being accurately generated. Errors in
break-out or chamfer position, which
would lead to errors in contact during
operation, can be identified and
corrected before material is cut.
There is a direct link between the gear
design and loaded tooth contact analysis
tools to automate selection. Tool design
and simulations of manufacturing
processes ensure machining
accuracy and resulting performance
characteristics such as strength, stress
and noise can all be assessed before
cutting metal. Engineers can also
make choices based on priority for
production such as minimum machine
time, maximum strength or power and
tool life. The system promises dramatic
savings in production time and cost.
The GPS has in recent years made it
possible to further close the gap in
gear manufacture by enabling a flexible
alternative to dedicated gear equipment
that utilises multi-axis CNCs for small to
medium batch, R&D or one-off gears
that may be cost and space prohibitive
to justify large capital investment in
dedicated equipment. Dontyne also

Collaboration between industrial
partners has enabled gear
manufacturers to take a fresh look
at how gears are designed, analysed,
machined and measured. Development
of bespoke software with machine
manufacturers has enabled companies
to migrate from expensive dedicated
equipment to flexible machine centres
and inspection platforms.

The major obstacle to taking
advantage of modern CAD and
machine tools for this technology
in this is human inertia; many new
ideas that work in theory have not
translated into good practice. There is
therefore a need for extensive real-
world testing. Since its inception,
Dontyne has associated itself with
recognised industrial institutions such
as the British Gear Association (BGA)
and the American Gear Manufacturers
Association (AGMA), thus ensuring
consistency in its calculations. DrFish
and Dr Palmer also contribute to
several ISO committees relevant to
gear production and have represented
the UK at these meetings on occasion.
Dontyne feels this is important not
only for consistency but also to drive
development of these standards with
new developments. The developments
can be shaped by results from Dontyne
testing programs but also from
research and development centres
within the UK. Dontyne is partnered
with Design Unit (DU), Advanced
Manufacturing Research Centre
(AMRC), and Advanced Forming
Research Centre (AFRC) – very valuable
assets to the UK, which keep Britain at
the forefront of the mechanical power
transmission industry.

The Rt Hon Theresa May MP's Foreword For The Parliamentary Review

By The Rt Hon Theresa May MP

This foreword from the then Prime Minister appeared in the 2018/19 Parliamentary Review.

British politics provides ample material for analysis in the pages of The Parliamentary Review. For Her Majesty’s Government, our task in the year ahead is clear: to achieve the best Brexit deal for Britain and to carry on our work to build a more prosperous and united country – one that truly works for everyone. 

The right Brexit deal will not be sufficient on its own to secure a more prosperous future for Britain. We also need to ensure that our economy is ready for what tomorrow will bring. Our Modern Industrial Strategy is our plan to do that. It means Government stepping up to secure the foundations of our productivity: providing an education system that delivers the skills our economy needs, improving school standards and transforming technical education; delivering infrastructure for growth; ensuring people have the homes they need in the places they want to live. It is all about taking action for the long-term that will pay dividends in the future.

But it also goes beyond that. Government, the private sector and academia working together as strategic partners achieve far more than we could separately. That is why we have set an ambitious goal of lifting UK public and private research and development investment to 2.4 per cent of GDP by 2027. It is why we are developing four Grand Challenges, the big drivers of social and economic change in the world today: harnessing artificial intelligence and the data revolution; leading in changes to the future of mobility; meeting the challenges of our ageing society; and driving ahead the revolution in clean growth. By focusing our efforts on making the most of these areas of enormous potential, we can develop new exports, grow new industries and create more good jobs in every part of our country.

Years of hard work and sacrifice from the British people have got our deficit down by over three quarters. We are building on this success by taking a balanced approach to public spending. We are continuing to deal with our debts, so that our economy can remain strong and we can protect people’s jobs, and at the same time we are investing in vital public services, like our NHS. We have set out plans to increase NHS funding annually by an average by 3.4 percent in real terms: that is £394 million a week more. In return, the NHS will produce a ten-year plan, led by doctors and nurses, to eliminate waste and improve patient care.

I believe that Britain can look to the future with confidence. We are leaving the EU and setting a new course for prosperity as a global trading nation. We have a Modern Industrial Strategy that is strengthening the foundations of our economy and helping us to seize the opportunities of the future. We are investing in the public services we all rely on and helping them to grow and improve. Building on our country’s great strengths – our world-class universities and researchers, our excellent services sector, our cutting edge manufacturers, our vibrant creative industries, our dedicated public servants – we can look towards a new decade that is ripe with possibility. The government I lead is doing all it can to make that brighter future a reality for everyone in our country.
