How waterjet cutting works

Even though waterjet cutting has only come into its own in recent years it may surprise you to know that it has been around since the 1930s. At that time it was used at a low pressure and only for cutting soft materials. Whilst things continued to develop after the war, waterjet cutting became much more effective in the 1970s, when the first reliable high pressure pump was developed.

Whilst the earlier waterjet machines could cut softer materials they could not handle harder materials and metals. The ability to cut harder materials like metal came about following the addition of an abrasive to the waterjet cutting nozzle. This was a technique first used in the 1930s, however early versions of the nozzle were not commercially viable. Further development of the nozzle and the availability of a reliable pump led to a more effective waterjet that could now cut through a bigger variety of materials.

Surprising benefactors of motorsport technology

When we think of the technical developments in F1 and motorsport generally, we can all probably think of an area in the automotive industry where those developments have had an impact. But do you ever think about what or who else benefits of those developments?
If I was to say that the care of premature babies has been impacted by motorsport technical developments you’d probably wonder how. What about supermarkets? How could they possibly benefit from the motorsport industry?

These are only a couple of examples of where motorsport innovation is being used to solve challenges in other industrial sectors.

Farnborough International 2016 in full swing

Whilst the weather may have put a premature end to the day on Monday, the Farnborough International Air Show is back on track with attendance and business at the trade show thriving.

Statistics earlier in the year were predicting one of the most successful shows yet with increased numbers of international participants in the trade show and conferences, and more dedicated country pavilions. In addition to first time country pavilions for Austria, Brazil, Republic of Ireland and China, Boeing has a special pavilion celebrating their centenary which falls on the Friday of the show.

The show has become the UK’s shop window for all things aviation from the civilian, defence and space sectors

Date set for the Bloodhound SSC record attempt

One month on from our last post about Bloodhound, the date for the first record attempt has been set. October 2017 will see the first land speed record attempt for 20 years.

The signing of a major deal means that the project has now secured funding to complete the car and start preparing for their testing in South Africa next year.

When Bloodhound went on display in 2015 it was as a trial build and without fluids. This was done to make sure that the 35,000 individual and bespoke parts actually fitted together. Brackets were checked to see if they were in the right places leaving enough room for service and maintenance activity as well as checking the tolerance of manufactured parts.

The advantages of waterjet cutting

There are many advantages of waterjet cutting compared to other methods, but if we had to try and summarise them neatly into a few words we’d say;

The ability to cold cut almost any material in any direction with less waste and a superior finish.

But really that’s not enough of an explanation, so let’s expand a little on that statement and address some of the areas of improvement over more traditional cutting methods.

Omni-directional cutting
Waterjet cutting allows omni-directional cutting – the ability to cut in any direction which gives much greater cutting flexibility. In most cases starting holes are not required as the water jet is able to perforate the material. It is now much easier to cut more complex shapes and designs into all sorts of materials.

Solar Impulse 2 crossed the Atlantic non stop

Solar Impulse 2 left New York on Monday 20th June and landed in Seville, Spain on 23rd June at 7.30 am. The total flight time was 71 hours and 8 minutes and now means that the aircraft has crossed both the Pacific and Atlantic oceans.

Solar Impulse 2 is attempting the first renewably powered circumnavigation of the globe and is now nearing the end of its 35,000km journey. The trip started in July 2015 and will finish back at the starting point in Abu Dhabi. The immediate next steps are to negotiate a route back to Abu Dhabi via Egypt or Greece.

Solar Impulse 2 has a wingspan of 72m and weighs more than 2 tons. It is powered by more than 17000 solar cells and achieves an average speed of 75 km/h.

Just like the Bloodhound project, the Solar Impulse 2 team are providing an educational platform around their project, giving resources to schools and universities as well as providing opportunities for live hangouts with members of the team.

Longest rail tunnel in the world opens in Switzerland

After nearly 2 decades of construction work, the Gotthard Tunnel, the world’s longest and deepest rail tunnel opened in Switzerland earlier this month.

The tunnel is expected to revolutionise travel between northern and southern Europe by providing a high speed rail link underneath the Swiss Alps, moving freight traffic off the road and onto the rails. It is estimated that more than a million lorry loads of freight will move from road to rail.

Whilst the tunnels have been officially opened scheduled services will not begin until December 2016 when up to 265 freight trains and 65 passenger trains a day are expected to run.

Bloodhound inspiring scientists and engineers of the future

At the end of April the Bloodhound Education team, combined with the BBC micro:bit project launched a huge competition for secondary school children; The Model Rocket Car Challenge.

Supported by the army and Microsoft among others, and forming part of the Guinness World record rocket car challenge, school teams are challenged to make foam rocket cars and race them through approved tracks; the aim of course, to be the fastest!

The races are being organised through the network of Bloodhound hubs and will see a series of regional heats that will lead up to a final at the end of June at the Santa Pod Raceway in Northamptonshire. The winners will spend a day watching Bloodhound test runs as well as securing a financial prize for their school.

New machinery is an investment not a cost

Developments in engineering and manufacturing are moving on at a pace. Continuing research into materials and their capabilities results in demand for more complex work requirements and those requirements mean more advanced machinery.

Whether you provide one service or many, older outdated machinery may eventually lead to less efficient production and an increase in costs. There probably are some areas of manufacturing that have remained unchanged for years and so the older machinery may well still be able to work effectively, but can it compete with more modern machinery that is more efficient and technically capable? A regular review of the machinery and equipment you use should identify if your business can be improved by investing in new machinery – and it should be seen as an investment, not a cost. Newer more advanced machines may open up markets and opportunities that you previously hadn’t been able to consider, ensuring your businesses longevity.
