How to Design for Rapid Prototyping

What is Rapid Prototyping?

Rapid prototyping is a technique used in the product development process to quickly create a physical prototype of a product or part using computer-aided design (CAD) data.

This process allows designers and engineers to test and validate their designs before moving into full-scale production.

Rapid prototyping can include techniques such as 3D printing, CNC machining, and injection moulding. These rapid prototyping methods create functional prototypes in a fraction of the time and cost compared to traditional manufacturing processes.

What is the Role of Design in Rapid Prototyping?

Design plays a crucial role in the rapid prototyping process as it lays the foundation for creating a successful prototype.

Design helps to define the functionality, form, and appearance of the prototype, ensuring that it meets the specified requirements and objectives.

In specific terms, design is important in rapid prototyping for several reasons:

Visualisation: Design helps to visualise the final product and enables all stakeholders to see and understand what the prototype will look like. This helps to align expectations and ensure that everyone is working to the same brief.

Iteration: Design allows for quick iterations and modifications to the prototype. By creating multiple design concepts and testing them, designers can quickly refine and improve the prototype to meet the desired specifications.

Feasibility: Design helps to identify potential challenges and constraints early in the prototyping process. By addressing these issues during the design phase, designers can avoid costly rework and wasted time.

Communication: Design serves as a visual communication tool that helps to convey ideas, concepts, and requirements to team members, clients, and stakeholders. It facilitates effective collaboration and decision-making throughout the prototyping process.

Overall, design plays a critical role in rapid prototyping by guiding the development of the prototype and ensuring that the final product meets the intended specifications.

Key Principles When Designing for Rapid Prototyping

Define clear objectives: Before starting the rapid prototyping process, it is important to clearly define the objectives of the project. This will ensure that the design process stays on track, and that the prototype can be measured against the pre-defined outcomes.

Start with sketches: Begin the design process with rough sketches to explore different ideas and concepts. This will help to identify the most effective design solutions.

Use prototyping tools: Utilise prototyping tools such as Sketch, Adobe XD, or Figma to create interactive prototypes that simulate the functionality of the final product. These tools allow for quick testing and refinement of designs.

Focus on user experience: Prioritise user experience by considering how users will interact with the prototype. Pay attention to usability, accessibility, and overall user satisfaction.

Iterate and refine: Rapid prototyping is an iterative process, so designers should be prepared to make changes based on feedback and testing. This will allow designers to continuously improve the prototype before moving to full scale production.

Test early and often: Conduct usability testing with real users throughout the prototyping process to gather valuable appraisals and insights, and to make informed design decisions.

Maintain consistency: Use consistent design elements, such as colours, fonts, and navigation patterns, throughout the prototype to create a cohesive and polished user experience.

Stay flexible: Be open to making changes and adjustments to the prototype as required. If the final product is to be successful in meeting the agreed objectives, product designers will need to accept constructive criticism and embrace new ideas.

Top Ten Design Tips for Rapid Prototyping

Anodizing for CNC Machined Parts

What is Anodizing for CNC Machined Parts?

Anodizing is a specialist surface finishing option for CNC machined parts.

It is an electrochemical process that creates a thin, protective oxide layer on the surface of a metal part, typically aluminium or its alloys. This oxide layer provides improved corrosion resistance, hardness, and wear resistance to the part. In addition, anodizing can also enhance the aesthetic appearance of the part by allowing for various colour options.

The anodizing process involves immersing the part in an electrolyte bath and applying a direct current, which causes the formation of an oxide layer on the surface.

Let’s look at this process in more detail….

What is the Process for Anodizing a CNC Machined Part?

The anodizing process involves several steps:

  1. Preparing the part: The first step is to thoroughly clean the part to remove any dirt, grease, or other contaminants from its surface. This is usually done using a solvent or detergent and water. This step ensures proper adhesion of the anodized coating.
  1. Surface treatment: After cleaning, the part may undergo a surface treatment process called etching or desmutting. This step involves the use of a chemical solution to remove any remaining oxides, scale, or residual metals that could interfere with the anodizing process.
  1. Anodizing bath: The part is then immersed in an anodizing bath, which consists of an electrolyte solution, typically sulfuric acid. The part serves as the anode, while a cathode is also present in the bath. When an electric current is passed through the bath, an oxide layer forms on the surface of the part due to the electrochemical reaction.
  1. Anodizing process: The voltage and current applied during the anodizing process are carefully controlled to achieve the desired thickness and quality of the anodized layer. The type of alloy used in the part, desired colour or finish, and other factors determine the parameters of the anodizing process.
  1. Colouring (optional): If a specific colour is required, the anodized part may be immersed in a dye bath. This allows the pores in the anodized layer to absorb the dye, resulting in a coloured finish.
  1. Sealing: After anodizing and dyeing (if applicable), the part is often sealed to improve corrosion resistance and durability. Sealing involves immersing the part in a hot water bath or applying a sealant to close the pores of the anodized layer.
  1. Quality inspection: The anodized part undergoes quality inspection to ensure that the desired specifications, such as thickness, colour, and surface finish, have been achieved. This inspection may include visual examination, measurement, and various testing methods.

What are the Different Types of Anodizing Processes?

There are various types of anodizing processes that can be used for CNC machined parts. Some of the more common types include:

Type I Anodizing: Also known as regular or decorative anodizing, this is the most typically used anodizing process. It creates a uniform oxide layer on the surface of the part and provides corrosion resistance and improved aesthetics.

Type II Anodizing: This type of anodizing is typically used for parts which do not require high wear resistance. The process involves placing the aluminium in a sulphuric bath instead of using chromic acid. Type II anodized parts can easily absorb dyes, paints, and adhesives.

Type III Anodizing: Also known as hardcoat anodizing or sulfuric anodizing, this process produces a thicker and harder oxide layer compared to Type II anodizing. It offers enhanced wear and corrosion resistance, making it suitable for parts exposed to harsh environments or for those which require increased durability.

Chromic Acid Anodizing: This type of anodizing, also referred to as Type I anodizing, uses chromic acid as the electrolyte. It forms a thin, dense, and corrosion-resistant oxide layer on the part’s surface. Chromic acid anodizing is often used for parts that require high-temperature resistance or electrical conductivity.

Titanium Anodizing: This specialised anodizing process is specifically used for titanium CNC machined parts. It forms a thin oxide layer on the surface, providing improved corrosion resistance, wear resistance, and colour options.

Hard Anodizing: Hard anodizing is a form of the Type III anodizing process that creates an even thicker and harder oxide layer. This process is commonly used for parts which require extreme wear resistance, such as pistons, gears, and bearings.

Coloured Anodizing: Anodizing can also be combined with colouring techniques to provide various colours on the surface of CNC machined parts. This is achieved by dyeing the porous oxide layer formed during anodizing or by using proprietary colouring processes.

The appropriate type of anodizing for a CNC machined part will depend on the desired properties, functionality, and aesthetic requirements of the part.

The Benefits of Anodizing a CNC Machined Part

There are several benefits of anodizing a CNC machined part, including:

Enhanced corrosion resistance: Anodizing creates a protective layer on the surface of the part, making it more resistant to corrosion caused by moisture, chemicals, and other environmental factors.

Improved durability: The anodized coating makes the part more wear and scratch-resistant, increasing its lifespan and reducing the need for maintenance or replacement.

Aesthetic appeal: Anodizing allows for a wide range of colour options, providing an attractive and decorative finish to the part. This is crucial for products which need to be visually appealing.

Improved hardness: Anodizing can significantly increase the surface hardness of the part, making it more resistant to scratches and dents.

Better adhesion: Anodizing provides a textured surface with excellent adhesion properties, making it easier to apply paints, adhesives, or other coatings.

Electrical insulation: Anodized coatings have electrical insulating properties, making them useful in applications where electrical conductivity needs to be minimised.

Eco-friendly option: Anodizing is a relatively environmentally friendly process compared to other coating methods. It doesn’t involve the use of heavy metals, or the types of volatile organic compounds (VOCs) often found in other surface treatments.

Overall, anodizing a CNC machined part can improve its performance, aesthetics, and durability, making it a popular choice for a wide range of industries and applications.

The Challenges of Manufacturing in China

For several years now, China has been the centre of global manufacturing. It is currently the largest producer of manufactured goods in the world. Many companies in the UK have relied upon China’s manufacturing output to create their products.

However, in the light of recent events across Europe and the rest of the world, this reliance has started to change, and China’s monopoly on global manufacturing has been weakened.

In this article, we will look at some of the events that have led up to these changes. We will also examine some of the key determining factors that have seen many UK companies return to manufacturing suppliers here at home as an alternative to those based in China.

China – The Age of Industrialisation

During the 1950s, China underwent a period of great economic change. Mao Zedong, also known as Chairman Mao (or Mao Tse-tung in the English-speaking world), was Chairman of the Communist Party of China for over three decades between March 1943 and September 1976. Under his leadership, China began a long and expansive period of industrialisation.

In 1952, 83% of the Chinese workforce was employed in agriculture. In 1953, with the help of the Soviet Union, Mao began an ambitious plan to bring industrialisation to China on a significant scale. The ‘Maoist Great Leap Forward’ plan was implemented between 1958 and 1961. Its goal was to transform the People’s Republic of China from an agrarian economy based on farming to a modern communist society with a strong economic base at its centre.

The Soviet Union gave the Chinese some of the most advanced technology in the world. They also sent many thousands of Soviet technical advisors to China to oversee some 156 industrial projects.

The overall result was a sea change in the Chinese economic model. China began to rely more heavily on industrial output. Over the next quarter of a century, the value of agriculture to the country’s GDP had declined from 70% in 1952 to 30% in 1977.

In 2022, the percentage of the workforce employed in agriculture had fallen to 24%, compared to 83% in the 1950s.

In 2021, China’s manufacturing output had risen to $4,865.83 billion, which represented a 26.04% increase from 2020.

Why Has China Become a Popular Choice for Manufacturing?

China’s position as the foremost manufacturing power in the 21st century is due to a few important factors:

Low labour costs: employees are put to work for long hours with few rewards. Industrialists benefit from gaps in employment legislation. Low-cost labour is also possible because of China’s high population. As there are so many people competing for jobs, the rate of unemployment is high, which in turn has driven down wages.

Lack of regulatory compliance: in order to maximise manufacturing opportunity, much of this sector has been almost completely deregulated to encourage investment and to promote exports of manufactured goods.

Quick lead times: Chinese manufacturers have gained a reputation for supplying goods extremely quickly.

Infrastructure/Business Ecosystem: China has invested heavily in an extensive infrastructure which enables it to hold great sway over its supply chain partners.

Low taxes and duties: goods can be exported to different geographical territories at low cost to the customer.

Poor environmental regulation: with little or no regulations for sustainable practice, the manufacturing industry is allowed to thrive at the expense of environmental wellbeing. Industrialists are also able to avoid waste management costs.

Absence of law to protect workers’ rights: Chinese factories do not adhere to the same laws which some of their overseas competitors are subject to, including laws relating to child labour, involuntary labour, working hours, and health and safety.

Government influence: government investment in domestic infrastructure combined with a favourable pro-business tax system has helped to keep manufacturing costs at a very low level.

Strong domestic economy: a strong economy has led to increased spending. This has increased the value of the Chinese Yuan (CNY) and has provided Chinese manufacturers with the opportunity to expand their businesses.

World Events which have Served to Weaken China’s Manufacturing Dominance

In recent years, we’ve witnessed many significant and quite unpredictable changes in the macro environment which have served to shake China’s stranglehold on the global manufacturing sector.

Let’s look at some of the key world events in more detail:

Ukraine war – the political turmoil in Eastern Europe has led to supply chain disruptions, export challenges, rising costs, and uncertainty in global financial markets.

Energy crisis – inflated energy prices have meant that Chinese manufacturers have had to increase their prices, the burden of which has been borne by the customer. This has made China a less attractive option than before.

COVID-19 – delays and shortages related to the pandemic have prompted many customers to re-evaluate their reliance on China, and to look elsewhere for an alternative solution.

US economic policy – the US Government’s hardline trade policies with China have resulted in a succession of costly tariffs which have driven prices up.

Continued lockdowns in China – as China struggles to break free from COVID-19, lockdowns are still part of day-to-day life, and have had negative implications for manufacturing activity.

Protests – over the past year, several demonstrations have taken place across China in protest against these sustained periods of post-pandemic lockdown. This unrest has had poor economic implications for China, as well as for overseas financial markets.

Reduced investment – these socio-political events have led to a reduction in investment in China. For a country whose success has been built on capital investment, this has negatively impacted its economic progress.

In addition to these factors, China has also been confronted with many other challenges, including increased labour expenses, accelerated manufacturing competition from other developing economies, and a series of ongoing trade disagreements.

All this activity has seen some companies in the UK and overseas disengage with China and move to quickly diversify their supply chains. In many cases, this has seen corporate buyers look to their own domestic marketplaces for new manufacturing partners.

What Does All This Mean for Chinese Manufacturing?

The pace of companies moving production out of China is accelerating all the time, with China losing more manufacturing and export market share in several of its key sectors.

Chinese manufacturing companies had always been attractive because of price. But in the light of recent global events, Chinese manufacturers are no longer able to offer pricing which is as favourable as it once was. This has undermined arguably the key selling point for these manufacturers when trying to secure new business from overseas customers.

Some UK-based customers have seen their costs of doing business with Chinese manufacturers go up by over 25%.

Coupled with this, the supply chain has now become more complex and challenging in the aftermath of COVID-19, the war in Ukraine, and the United Kingdom’s exit from the European Union. Goods can no longer be depended on to arrive on time every time from the other side of the world.

Geopolitics is also a concern for some customers. The Chinese Government’s support for Russia, its diplomatic issues with the United States, and its aggression towards Taiwan has seen some UK based customers begin to question their support for Chinese manufacturing.

Here are some other key reasons why China has lost some of its pulling power:

  • Uncertainty over IP Protection: Intellectual Property (IP) laws are less robust than in many other countries, with low penalties for IP infringement. This makes it difficult for UK designers to protect valuable IP in a country where counterfeit is possible.
  • Competition with neighbouring economies: local nations such as India, Vietnam and Indonesia have provided increased competition to Chinese manufacturers by benefiting from even lower labour costs and reduced levels of regulation.
  • Economic downturn: China is currently experiencing adverse changes in their economic cycle, with manufacturing companies being squeezed by slow economic growth and rising costs.
  • Reduced foreign investment: there has been an increase in the number of investors leaving China in recent times. Overseas investors are concerned about security, government policy, and a lack of action on reform promises, according to the European Chamber of Commerce in China.

What is Reshoring?

Reshoring is the process of returning product manufacturing back to its country of origin. It essentially involves bringing production activities back from overseas to wherever the company who owns the products is based.

In recent times, the UK manufacturing industry has seen a significant increase in the number of domestic companies who have brought production of their goods back to the UK.

Overseas manufacturing outlets have become a less attractive option in recent years due to several reasons.

Let’s explore some of the external forces that have put pressure on overseas manufacturers….

Key Reasons for Abandoning Overseas Manufacturers

Longer lead times – Some overseas manufacturers have traditionally operated on very short lead times, particularly those in Asian markets. This has made them very attractive to UK customers who need parts fast. However, in recent times, changes in the global political landscape have stifled international supply chains resulting in less timely – and in some cases, unreliable – means of delivering products to other parts of the world.

Price – supply chain pressures and economic volatility has meant that some overseas manufacturers are no longer as competitive. Some UK-based customers have seen their costs of doing business with Chinese manufacturers go up by over 25%.

Ukraine war – the political turmoil in Eastern Europe has led to supply chain disruptions, export challenges, rising costs, and uncertainty in global financial markets.

Energy crisis – rising costs have meant that Chinese manufacturers have had to increase their prices, the burden of which has been absorbed by the customer.

COVID-19 – delays and shortages related to the pandemic have prompted many customers to re-evaluate their reliance on China, and to look elsewhere for an alternative solution.

Geopolitical factors – China has found itself on the opposing side of the table during the current Russia/Ukraine situation, which has left it at odds with many European customers.

Environmental issues – British companies are under increasing pressure to ensure compliance with environmental and corporate social responsibility best practice. Countries with poor human rights records, or those who do not protect workers’ rights, are rapidly becoming less attractive partners.

Why UK Companies are Moving Their Manufacturing Back Home

  • Greater certainty around delivery times
  • Less potential for supply chain disruptions
  • Easy, more flexible collaboration with domestic suppliers
  • The language barrier is eliminated, and communication is more open
  • Reduced supply chain complexity
  • Greater confidence in the quality of the final components
  • Cost advantages of overseas production are now less favourable (in China, for example, unit labour costs have risen sharply in the last few years)
  • Reduced shipping costs – the price of shipping goods from Asia, South America, and mainland Europe has increased dramatically, with serious implications for UK SMEs.

Some studies suggest that up to 40% of small businesses are considering a switch from overseas manufacturers to UK manufacturers, so that they can remove import challenges post-Brexit and reduce rapidly rising freight costs. These costs, coupled with increased legislation and bureaucracy, have made overseas manufacturing a financial and logistical headache for many UK businesses, eroding profit margins and stifling growth.

Manufacturing in the UK

The UK is known across the world as a manufacturing power. We have a rich history of making products and exporting them to the rest of the world. We are skilled in innovation, with advanced technologies and infrastructure to support manufacturing of all kinds.

Despite changes in the recent socio-political environment, such as Brexit and COVID-19, we remain a highly competitive option for companies at home and abroad who have a requirement for British manufacturing.

Let’s look at what makes us so unique….

Skilled manufacturing professionals – for centuries, the UK has had a distinguished history of manufacturing. Through the generations, we have demonstrated a strong tradition of producing expert engineers and technical craftsmen and women, which sustains to this day.

Education – the UK has some of the best universities in the world, with some of the most talented young engineers graduating every year, many of whom go on to embark upon careers as design engineers, product designers, and manufacturing professionals.

Dynamic supply chain – there are a range of support services which are available to manufacturers, such as management consultants and financial experts.

Research and Development (R&D) – the UK Government has invested in many research and development facilities to support companies who are looking to manufacture products in the UK.

Infrastructure – the UK has a well-developed infrastructure, including excellent transport networks and strong access to raw materials.

Legislation – clear and robust legislative policies which have been passed into law to protect businesses and to support entrepreneurial endeavour, including intellectual property (IP), patent protection, and trademarking laws.

Pro-government business support – post-Brexit, the UK Government has introduced a range of measures to support British businesses, including regulatory reform and tax incentives.

Stable political environment – the UK is a stable democratic country which has one of the strongest legal systems in the world. This stability provides businesses looking to manufacture products in the UK with confidence and security that any capital investments will be protected under the right of law.

New Product Development

What is New Product Development?

New Product Development (NPD) is the act of creating a new commodity or product for the commercial marketplace. It is essentially a series of steps that are taken from inception to roll out which see a new product designed, manufactured, and unveiled to the world.

NPD is an important activity for most companies. It is a means by which companies can stay ahead of their competitors, provide added value to their customers, and increase organic growth.

New products provide an opportunity for companies to sell more units and therefore increase revenue streams. NPD activity also allows companies to grow their market shares.

In a world where there is strong consumer demand, greater competition, and where changing digital and technological advancements are emerging all the time, it is important for companies to keep driving forward and developing their product range. Standing still in this environment will likely lead to rival companies gaining competitive advantage.

Fast-moving change has become an accepted – and expected – part of consumer culture. Customers of all types in all different industries have an expectation for companies to adapt and evolve, and for their product range to develop in a manner which reflects these rapidly changing times.

New products are designed to either solve an existing customer problem in a new or innovative way, or to enhance or move forward a similar product which is already out there in the marketplace in a much more rudimentary format.

The product development process is multi-layered and involves many internal and external stakeholders. As noted above, it involves several different steps, or stages.

Let’s look at these stages in more detail….

The Key Stages of New Product Development

Idea Generation

All new products start life in the same way – as a concept or idea. Each product is the brainchild of an individual or group of individuals.

The process usually involves a brainstorming session between product designers and product engineers. It may also include other stakeholders, such as marketing experts.

At this stage of the process, ideas are discussed and explored, with the relative merits of each being assessed before the optimum concept is identified for further development.

If done correctly, the idea generation phase should be the consequence of detailed research which has already been conducted to identify what gaps exist in the current market for NPD, and what problems any potential new product should be introduced to solve.


Once the idea generation phase of the process has been completed, the Research phase begins.

By this point, a product idea will have been formed. The next step will be to further develop this idea by testing its likely suitability for the current marketplace.

To do this, research must be conducted. This research can take many different forms and can comprise either market research (where a sample of the target market is selected to answer questions on their consumer habits and tastes) or competitor analysis to determine how to potentially position this new product in relation to the competitors’ offerings.

This stage of the process also provides an opportunity to gain feedback from target consumers on what they think of your ideas before you advance too far down the road of developing your new product.


This is where the information collected in the previous stage is reviewed against the original concept, and any changes to the idea based upon the feedback provided are implemented.

At this stage in the process, the strategic goals and objectives for the product can be reviewed and finalised, and the overall concept can be refined to reflect these milestones.

The estimated product value and capacity can also be determined.

As soon as the concept has been clearly defined, the next step of the planning phase will be to source suitable manufacturing partners to help to take the project forward.

It is also where marketing professionals, either in-house or commissioned from outside of the organisation, will have to start thinking about how to successfully bring this new product to market once it is ready to launch.


The prototyping phase is where a physical prototype of the product is created with the help of whichever manufacturing partner/s has been chosen during the planning stage.

It is essentially a to-scale basic version of the product.

The prototype will help product designers and product engineers to understand how the product functions and looks in its true physical format.

Prototyping is a very important phase in the product development cycle. No matter how impressive the product concept might be, or how meticulous the planning, the prototyping phase will often unearth several key aspects of the design which have not necessarily been accounted for in the theoretical planning stages.

It also allows manufacturing partners to find solutions to complex manufacturing challenges before full scale production begins. It is important to go through this process so that the best solution for the manufacture of the product can be decided upon before producing the product at volume.

Consumer Testing

This is where consumers are invited to test the prototype and to provide feedback on its functionality, appearance, and positioning within the current marketplace.

The testing phase is essential in order to assess the commercial viability of the product and as a way of identifying any prototyping issues that may need to be ironed out before launch.

Often, the results of this feedback will mean that changes need to be made to the prototype to reflect consumer opinion.

It may be necessary to go back and forth between the prototype and the testing phases, making multiple changes and conducting several stages of consumer testing in order to get the final prototype absolutely right.

As soon as the prototype is produced in a form that consumers and product engineers are happy with, full-scale product development can begin.

Product Development

As soon as the prototype phase is concluded, a final cost analysis will be conducted to determine the commercial feasibility of producing the finished prototype at volume.

An original cost analysis should have been conducted before now, most likely at the research or planning stages, but a final analysis will also be needed if there have been any changes to the prototype since those preliminary calculations were made.

Providing the numbers still add up, full scale production can commence.

The production process will be carried out by the manufacturing partner identified at the planning stage. This can be the same production company who produced the prototype or a different one.

If costs prove to be prohibitive, or if a suitable prototype which meets the original objectives cannot be produced within the accepted cost parameters, the project may be abandoned.


At this stage of the process, the final product will have been produced and will be ready for the marketplace. Before it can be made available to the public, the branding of the product will need to be concluded.

This includes the development of the brand name, product slogan, packaging, price points, and the marketing message behind the product.

Marketers will also seek to position the product in the optimum space relative to its competitors. If it is a product which will be sold directly to the consumer, agreements with distributors such as retail outlets may also need to be finalised at this stage of the process.

Product Launch

This is the stage of the process where the product enters the public domain. The product development team has completed their work, and the exciting moment has arrived. It is also the phase of NPD which is known as the commercialisation phase, or the market launch.

At this stage, the product becomes available for purchase. The marketing strategy supports the sales of this new product, helping to raise awareness and create interest amongst the target demographic.

This is the stage of the process where the product takes on a new life of its own, independent of its creators and manufacturing partners.

It is also the first stage of the process where the product can start to deliver sales revenue, and a financial return can be enjoyed. This is where the company can begin to recoup some of the money invested in the product’s development, with new gains compensating for the expenditure incurred in getting the product to market.

Post-Launch Review

As with any big commercial undertaking, it is important once the work has concluded to review the process in full. This review should include each of the key players, including the product designers, product engineers and marketing specialists, to determine what was successful and what wasn’t.

In the fast-moving pace of modern business life, this is the stage of NPD which is either usually forgotten or neglected. But it is an essential element of the wider process.

NPD can be an expensive and time-consuming process. It is also central to the success of the company since the new products which are launched are crucial to achieving success for the organisation in the many months and years ahead. If mistakes have been made, it is important that these mistakes are not repeated when the next new product is launched.

Too many mistakes over a long period of time can end up harming the quality of the final output. If products are sub-standard when they are launched, or positioned incorrectly, they will not achieve the sales targets that have been set for them, resulting in reduced revenues and costly expenses. This can have a detrimental affect on company growth and performance, and can also mean that competitive advantage, as well as market share, is lost.

Identifying mistakes in the process and implementing this feedback into the product development process will ensure that future new products are given the best chance to succeed and flourish in the increasingly competitive marketplaces of the 21st century.

What is CNC Machining?

CNC Machining

CNC is the abbreviated term for Computerised Numerical Control. This is a computerised manufacturing process in which pre-programmed software and code operates production equipment. This equipment is often complex and includes grinders, lathes and turning mills.

As a subtractive manufacturing process, a range of tools are used to cut contours and shapes into a workpiece in order to create parts. The high level of automation means that CNC machining is suitable for both prototype and low-medium volume production.

A 3D model of the design is created using CAD software and is converted into a CNC programme. The machine is then programmed using the G Code, which informs the machine of precise measurements, such as speed, feed rate and coordination. The machine then removes material from the workpiece to produce the custom-designed part.

Many different types of materials can be CNC machined, including metals, plastics, glass, and foam.

Different Types of CNC Machining

3-Axis Machining

The two main types of 3-axis machining are CNC milling and CNC turning. The chief distinction between the two is that CNC milling uses a rotating tool and CNC turning uses a rotating part.

Let’s now look at each of these methods in more detail:

CNC Milling

During CNC milling, the cutting tool is attached to a spindle and can move in three different directions: along the X, Y and Z axes. It rotates at high speed to remove material from the workpiece.

Multi-axis milling allows 4 or more axes to provide added dexterity to the operation. 5-axis machines are commonly used and can create all kinds of parts within the accepted parameters of CNC milling.

CNC milling produces a flat or sculptured shape in the workpiece. The operation is performed on a milling machine using a multi-point cutting tool, also known as a milling cutter. The cutting tool cuts intermittently during the process.

CNC milling is ideal when straightforward cutting is required. However, for more complex geometries 3-axis CNC milling can have its limitations. As there are only 3 axes, the cutting tool may not be able to interrogate every part of the workpiece.

An advantage of this particular method is that parts can be produced to high tolerances and the setup costs are low.

CNC Turning

For CNC turning, the workpiece is held in a chuck and rotated, and the tool is applied to the object piece to remove material. A stationary cutting tool is applied to the surface of the rotating bar stock, and unwanted material is removed. There can be several cutting tools used to achieve this.

Unlike with CNC milling, the tool does not rotate but moves around the workpiece radially and lengthwise. It is a highly accurate machining process which is suitable for achieving tight tolerances.

The speed of the cutting will be dependent on the type of machine, the material being used and the main features of the component.

The cutting tool remains in continuous contact with the workpiece for the duration of the process. It is performed using a single point turning tool, also known as an SPTT.

CNC turning machines are also known within the industry as lathes. The increased machining speed reduces manufacturing costs, improves lead times, and makes large volume production more viable. However, because it is only suitable for cutting cylindrical shapes, its geometries are limited. It is, therefore, more commonly used as a secondary step when an additional feature is required.

5-Axis Machining

5-Axis machining (multi-axis machining) is a versatile process which provides more options and scope to the machining process than either CNC milling or CNC turning.

5-axis refers to the number of directions in which the cutting tool can move. It moves across the X, Y and Z linear axes, and rotates on the A and B axes. This means that it can approach the workpiece from any direction, thus adding greater versatility, accessibility, and sophistication to the process.

In essence, it means that a single component can be machined at 5 angles all at the same time.

There are savings to be made in terms of cost and lead times, and it is also possible to achieve more complex geometries than those which would be achievable with 3-axis machining.

This method also produces a smoother surface finish, and the accuracy of the final parts is usually high. The process is single setup, which also reduces the amount of manual labour required.

Advantages of CNC Machining

High level of automation which reduces the need for human input

Ideal for rapid prototyping, as parts can be produced very quickly

Ease of repeatability

Cost-saving exercise for prototyping or one-off designs, as there is no need to make custom tooling

Parts produced are often highly accurate and capable of achieving tight tolerances

CNC Machining by Industry

CNC machining is used for applications across a wide variety of business sectors. It is particularly useful in industries where a high level of precision and accuracy is required. Products and components which need to pass rigorous safety tests will significantly benefit from CNC machining.

Let’s take a look at the specific applications of CNC machining in some key business areas…

Automotive – gears, pins, brakes, shafts, valves, axles, and cylinder blocks

Aerospace – manifolds, bushings, landing gear and engine components

Medical – surgical instruments, dental implants, titanium joints and orthotics

Electronics – housings, computer motherboards, breaker panels, RFI shields and electrical insulation

Additive Manufacturing vs Injection Moulding

In our two recent technical articles, we investigated additive manufacturing and injection moulding. We explored them as two very distinct processes which are aimed at achieving the same thing…. the creation of plastic components for prototyping or low-medium volume production.

We will now look to summarise what we have learned from our examination into additive manufacturing and injection moulding.

We will also highlight the key advantages and disadvantages of both methods.

Injection Moulding

Injection moulding refers to the manufacturing process of producing parts by injecting molten material into a mould. The material, often plastic, is injected into the mould cavity in order to create a part. Once inside the mould, the material quickly cools, and the part takes its final solid shape.

Additive Manufacturing

Additive manufacturing is the process of creating parts by adding layers of material. Using this process, there is no need to create a mould to produce a part. The part is made by creating a CAD file which then talks to a machine and adds material until a part is formed.

Let’s look at the key parameters of both methods, examining in more detail the specific pros and cons associated with each process.

Injection Moulding


  • Advantageous if large volumes are required
  • Produces parts that are high in precision
  • The process allows for great ease of repeatability
  • Extensive choice of materials with different properties
  • Highly suitable for mass production
  • Generates production intent parts from the tooling, making them ideal for market testing
  • Low cost per part. This is particularly useful in circumstances where parts will need to be run off the existing tool at regular intervals over a sustained period of time
  • Greater scalability: can produce low volume prototype parts through to tens of thousands
  • Ideal process for components that require high detail
  • Parts produced often have greater strength and durability
  • More suited to larger components than additive manufacturing
  • Perfect choice for bulk production
  • Results in a better product surface finish
  • Improved functional integrity of parts, which are more visually appealing and reliable
  • Most plastic used during this process can be reground, recycled and reused


  • Up-front capital investment in tooling can be prohibitive
  • This process can result in higher amounts of plastic waste
  • Increased project turnaround times
  • It can be challenging to change tooling to optimise or iterate new designs

Additive Manufacturing


  • Ideal for rapid prototyping as this process allows for quick and easy production runs
  • Works well for low volume production runs
  • Ideal for complex or intricate component designs where detail is important
  • Low entry costs and reduced material costs
  • Suited to projects where the design goes through several iterations
  • Highly flexible and agile process which ensures precision of final design
  • Modifications can be made easily using 3D modelling software
  • Time and cost savings can be achieved where there is no requirement to build a tool
  • Produces less material waste
  • Parts produced may be more ergonomic
  • Reduces inventory and storage burdens as there is no tooling that needs to be housed
  • Increased digital inventory reduces carbon footprint and improves sustainability credentials
  • Manufactures directly from 3D CAD files so the location of manufacture is more flexible
  • As it is a digital process, it can be stopped post-part build or post-run, and restarted with punitive cost


  • Suitable for small plastic parts or components, but there are limitations with larger products
  • Unsuitable for large volume production runs
  • This method doesn’t allow for printing in production intent grade material
  • Surface finishes can be problematic, often creating a ridged surface, which can be an issue when producing parts that will rub against one another
  • Despite the initial set up being quick, the overall process can be slow, as most printers can only build one item at a time, which creates a significant challenge for detailed designs


Additive manufacturing and injection moulding are two very distinct processes with a range of advantages and disadvantages associated with both methods.

Additive manufacturing is ideal for very small production runs and offers quick turnaround times. Changes to the designs can be made easily and it is a process which suits the production of relatively small components.

Injection moulding is ideal for parts of all sizes and can accommodate prototype, pre-production, and production volumes. The costs are low per part and the process allows for ease of repeatability.

Choosing the right process is dependent on the end application of the component. Knowing how the product must look and function will usually determine which process a customer chooses. Such factors might include smoothness of finish, strength and durability, and heat or pressure resistance.

Industries that are highly regulated, and in which product safety and liability is a key factor, such as the aerospace and consumer goods sectors, may also dictate which process is most suitable.

However, it is worth noting that although this article has explored these two processes in direct opposition to one another, some now argue that both practices can occupy a common ground.

Indeed, many manufacturers and product engineers now regard additive manufacturing and injection moulding as complimentary rather than competing technologies. Combining these techniques can reduce pre-production cycles and allow for better testing and manufacturing.

What is Spark Erosion?

Spark Erosion

Spark erosion is a machining process where a specific shape is obtained using electrical discharges.

Material is removed by generating sparks between an electrode and the workpiece.

It is often adopted in circumstances where complex or intricate shapes need to be engineered. Often, these shapes would be too challenging to create using conventional cutting methods. It is also employed when dealing with challenging or robust materials.

Spark erosion is known in the industry by many different terms, some of which you may have heard of before. For instance, you may have heard it referred to as electrical discharge machining (EDM), spark machining, or die machining.

Regardless of what name you may know it by, spark erosion can be an invaluable part of the metal fabrication process.

Let’s look at the process itself in more detail…

The Process

Spark erosion is performed on hard metals, most commonly either on aluminium or steel.

The process involves removing material.

This is achieved by two electrodes, which are mounted on the machine. Current is discharged between the two electrodes and the process is supported by an electric voltage.

Dielectric fluid is used to ensure that electric charges do not flow through the workpiece. It helps to insulate the workpiece until discharge can occur. This fluid also acts as a coolant for the workpiece and the electrode. This is an important part of the process as temperatures can become very high.

The cutting tool moves along the object, cutting a path as it goes. At no point in the process does the cutting tool itself ever touch the surface of the metal.

Sparks move between the workpiece and the electrode, where electrical energy becomes heat, and results in the melting of the work material.

Advantages of Spark Erosion

– A fine level of detail can be achieved. This is particularly important when working on projects where tight tolerances are required
– Supports projects where complex machining is necessary
– Used for a wide range of surface finishes/textures
– Harder materials can be cut more quickly compared to conventional machining methods
– No cutting contact, so the integrity of the material is always maintained
– Highly controlled process which allows for precision and accuracy, even on softer materials
– Versatile in its applications to metal. Spark erosion can be applied to many different types of metal, as long as they have low levels of electrical conductivity
– Ideal for jobs which require the drilling of very small holes

Spark Erosion at RP Technologies

Here at RP, spark erosion is a fundamental part of what we do, and it has been used on several key projects for many of our customers. It has enabled us to create tools which meet the specific requirements of the drawing specification.

Many of our competitors do not use spark erosion. Instead, they ask their customers to change their design so that it is less complex and can be machined more easily.

These changes can be time consuming and costly.

Our “Without Limits” philosophy means that we build tools to meet the specific needs of our clients, no matter how complex the component design or process.

Sometimes, we employ spark erosion to achieve this. Indeed, it has become such an important part of what we do that we want to ensure we are as well prepared for the challenge as possible.

Consequently, we have recently promoted one of our tooling engineers, Garry Duffield, to the full-time position of EDM Engineer. After receiving three months of intensive onsite training, Garry has now also completed a three-day training course at Sodick.

Our Use of Spark Erosion

We were recently asked by a new client to help them with a new-to-market product which was designed to improve environmental sustainability in the farming and agriculture sector.

The design of the product itself was so complex that many of our competitors would not have been able to produce the parts in a manner which was faithful to the original drawings.

The features were incredibly complex, and the shaping was so intricate that it required some very high precision engineering. One of the main problems was that we were unable to cut using traditional cutting methods and machines.

We engaged in open dialogue with the client, supporting them to achieve their original vision for the product. We gave them advice and guidance and talked them through the potential solutions.

Through some further in-house discussion between our CAD designers and production engineers, we decided that the only way to maintain the integrity of the design would be to use spark erosion.

We used our own onsite Sinker EDM AD55L machine to do this. This machine features Sodick’s Linear Motor Technology. It provides rapid acceleration while ensuring optimum performance at high speeds. It also reduces distortion and improves rigidity by 70%.

This machine allowed us to overcome the complexity of the engineering requirements, achieve a fast turnaround of parts, and to ensure a smooth finish without any flaws or discrepancies.

Our client was incredibly happy with the finished components, complimenting us on our speed of delivery, final product quality, and the way in which we were able to find an ideal solution to a complex problem.
