PRV Engineering 2018 Highlights

Another year has gone by and what better way to end it off than reflecting on the last 12 months. As a specialist engineering company, we work with a wide array of industries and our experience has enabled us to deliver interesting, relevant and informative articles. From engineering and manufacturing to new technologies, defence updates and future combat vehicles, we publish new content every week. After all, you can’t grow unless you learn something new every day.

With Christmas behind us and the focus shifting to the New Year, let’s take a look at some of the PRV Engineering blog highlights from 2018. Most articles focus on PRV Engineering services but we also added a few very interesting developments from around the world.

Waterjet Cutting Essentials

The evolution of hydro-abrasive waterjet cutting has been remarkable and is one of the most effective methods of machining. There is no heat affected zone (HAZ), the small cutting widths and omni-directional cutting means we can machine virtually any material with high precision and accuracy. As a result, waterjet cutting produces a much-improved product finish with little to no secondary processing needed.

Advanced technology and methods make waterjet cutting far more environmentally friendly. So much so that the dust, chippings or gas produced with other cutting methods do not occur. There is also no need to change tool heads, blades or lubricants for each type of material which means machining time is greatly reduced.

This highly versatile cutting method produces much less waste than other forms of cutting which allows for more diverse design. The ability to cut more intricate designs and patterns offers

What’s Trending in Waterjet Cutting

Over the past few decades, abrasive waterjet cutting have evolved significantly. From a relatively crude cutting tool in the early 1980’s to a more sophisticated machine tool used in various sectors ranging from aerospace, mining to the food industry. This evolution is mainly due to better material development, more efficient system design, improved control of the waterjet tool and the progression to achieve higher pressure.

What materials can be machined using waterjet cutting?

Waterjet cutting is one of the most effective methods of machining materials. With no heat affected zone, small cutting widths and omni directional cutting, virtually any material can be cut with precision and accuracy. Because of this, waterjet cutting results in better product finish with little or no secondary processing needed. In addition, waterjet cutting is more environmentally friendly as the dust, chippings or gas produced by other cutting methods does not occur. In addition, as there is no need to change tool heads, blades or lubricants for each material, machining time is also reduced.

Plastic, rubber, wood, glass, metals and composite materials can all be cut using a pure waterjet or hydro abrasive waterjet cutting. For some materials the addition of an abrasive agent is needed to aid effective cutting. Below is an overview of the types of materials that can be cut.

PRV Engineering continue to invest

Investment in equipment and staff is extremely high on the list of priorities for PRV Engineering. Quality and customer service excellence are 2 of the most important things for the company and to provide those things equipment and staff need to be of the highest level.

In 2016 more new machinery has been installed at PRV Engineering and staff have completed training so they are fully up to speed on the operation and capabilities of each machine.

Hydro-abrasive waterjet machinery along with large format machining equipment were the latest additions to the workshop floor.

The beauty of waterjet cutting

When we say the beauty of waterjet cutting, we don’t just mean it’s a great, effective cutting process – we do actually mean the beauty that can be created with a waterjet. It’s a highly versatile cutting method that produces much less waste than other forms of cutting, which in turn allows for more diverse design. The ability to cut more intricate designs and patterns allows for more artistic license to be given to designers. More complex, artistic design often leads to a more beautiful end product.

So, we genuinely mean beauty in more than one sense.

The ability to cold cut means that almost any material can be cut without the adverse impact of heat; there is no heat affected zone. Multiple small cuts, swirls and channels can be made without the material bending, warping, burning or having any sort of reaction.
In addition to having no heat affected zone, what else makes waterjet cutting so versatile and effective in creating complex and diverse patterns and designs?

Laser, plasma or waterjet cutting?

When you work in manufacturing you have a decision to make; laser, plasma or waterjet cutting? ‘Which one is best?’ is the first question that many people ask. The most up to date and technologically advanced must be the best, surely? Well that’s not the case. In fact there could be a case for using any or all 3 of the manufacturing processes depending upon your needs and what you value most from the machine.

Each has its own advantages and disadvantages, from speed to cost and even waste. So let’s take a look at each option.

Supply chain opportunities come with the approval of Hinckley C

The recent approval for the new nuclear plant at Hinckley Point had businesses across the region breathing a sigh of relief. Hundreds of companies locally and further afield pre-registered to become part of the supply chain solution for EDF Energy and its contractors with the aim of securing long term work in the region. With 90 major tier 1 contractors requiring further supply chain contracts of their own, the opportunities for businesses in and around the region are huge.

Many smaller local businesses took the step to improve their own staff development and training and internal processes with the aim of being ready and able to meet the demands of the project. The project which will take approximately 10 years to complete will provide more than 25000 jobs and have more than 5000 people working on site at any time. It is anticipated that it will provide 900 permanent jobs on completion.

CNC Machining is moving to the desk top

There are few products that we use in everyday life that have not had CNC machining take some part in their production. Cars, planes, household machines and appliances, medical parts and toys all get to visit the CNC machine at some point in their production.
CNC or Computer Numerically Controlled machining has become more versatile then ever over the years. The number of axis has increased and the types of machine available now mean that increasingly smaller and more intricate parts can be manufactured using CNC machining.

The versatility of waterjet cutting

Waterjet cutting has really come to the forefront of manufacturing in recent years because of its versatility. There are an array of reasons to choose waterjet cutting over other methods, and they aren’t all about the actual cutting control. Improved efficiency in processes and reduced wastage and costs also factor highly, which by default leads to improved customer service.

Omni directional cutting, cutting widths, stress free cutting and improved finishing are all advantages of using water instead of more traditional cutting methods. However, one of the most fundamental things with waterjet cutting is that when you use water, there is no Heat Affected Zone (HAZ). This is the area around where you’re machining that gets hot because of the machining process. The heat generated in this area means the structure of the material gets altered and can be liable to fracture. If machining composite materials using traditional methods, the HAZ can cause all sorts of distortions and reactions, resulting in breakage and wastage. The ability to cut cold removes all these barriers and means that almost any material can now be cut with no alteration to its base structure.
