The Future of Computer Numerical Control (CNC)

Computer numerical control (CNC) has transformed the industrial manufacturing and homemade design fields tremendously over the past few decades. With automation and precision being the two key components of CNC, it’s truly amazing what can be designed today compared to just one generation ago. So, imagine what the future of CNC technology may hold.

Some leaders in manufacturing have posed the question about whether current forms of CNC programming developed by humans will even be necessary in the future. With knowledge-based machining processes, adaptive and closed loop machining, along with automated feature recognition becoming more advanced each day, many experts predict that human CNC programmers will be in much less demand in the near future. This means a programmer-oriented field could endure a very drastic change over the next several years.

Looking Into The Near Future of CNC

Just a few years ago, 3D printing was nothing more than an afterthought for many individuals. Now, it appears as if it could completely replace what we’ve come to know as traditional manufacturing methods. Known as additive manufacturing, 3D printing builds layers of materials to create objects. 3D printers are currently available on the market, and many are very reasonably priced and are being used by individuals in their homes for what is essentially personal manufacturing.

As for CNC technology, CNC machines have already begun to drop in price and are becoming more readily available to the public. Expect to see a continued decrease in the price of these machines. Plus, they’ve become easier to use, and you don’t have to be a math whiz or have manufacturing experience to both assemble and utilize a CNC mill, lathe, or plasma cutter. The main difference between CNC machines and 3D printers is that CNC tools take away – or subtract – materials for large pieces to create an object, whereas 3D printers add materials.

Why CNC Size Matters

Much like personal desktop computers, cell phones, radios, and MP3 players, CNC machines have already started getting smaller. While they are becoming more compact like other forms of technology, this decrease in size has made CNC machinery easier to store. Hence, more machinery and manufacturing enthusiasts have had the opportunity to store and use CNC machines right in their homes. This trend will likely continue, and the machines will gain even more features for customization.

The Bottom Line

Despite changes that occur in any industry and with any technology, there is certainly a bright future ahead for CNC machining. To see any piece of technology make our lives easier and more efficient is a great thing. With the continued growth of smaller and more affordable CNC equipment, the next great inventor might be able to achieve incredible success in his or her own living room using a CNC machine.

How CNC is Used in the Aerospace Industry

The aerospace industry encompasses all types of air traffic, from massive Boeing 747 jets that carry hundreds of passengers to spacecraft rockets designed to travel to the International Space Station, the moon, and even Mars for exploration purposes. Aerospace technology is made with some of the most incredible precision imaginable. As such, computer numerical control (CNC) fits quite well into this field where such amazing pieces of transportation are developed.

CNC in Aviation

Aircraft carriers, from two-person private jets to commercial airplanes that carry a few hundred passengers around the globe, must be constructed with the utmost precision. This precision includes all facets of production, from the engine of the aircraft to the outer body of the jet. A CNC machine can play a critical role in quickly and precisely manufacturing specific tools that aid in the operations of each plane component. For example, in order for a plane’s engine to maintain an 8-hour flight, it must be designed to properly process and utilize the fuel inside it. A barely visible piece within the engine may be created with a CNC machine. The same may be said for the plane’s cockpit, which likely includes an intricate computer system to ensure the plane reaches its intended destination. In addition to these inner workings of a jet, the outside design like a plane’s wing could be modified with a CNC machine with extreme precision so that the wing functions through the air properly and efficiently.

CNC in Space Exploration & Travel

When you think of space exploration and travel, the names NASA or SpaceX probably come to mind right away. These organizations have designed some of the most powerful rockets in the world that can traverse millions of miles around the solar system. CNC machining processes have been used to manufacture necessary components of all spacecraft types, from the inner workings to the body design. Spacecraft are designed to maintain themselves in outer space for months – or even years. With this long-term maintenance in mind, they must be developed with incredible precision and accuracy. From the computer system inside a rocket ship to the engine made for extreme durability, these transporters require the utmost attention to detail when on the assembly line. Safety is also a major factor at play, in addition to storage equipment for astronauts who take lengthy missions to space.

Industrial CNC Manufacturing

Due to the high-powered nature of airplanes and spacecraft, industrial CNC manufacturing processes are certainly much more common than private, homemade attempts at CNC machining. As such, there is a great deal of expense involved in designing parts for the most powerful forms of transportation we enjoy today. That is why only the most wealthy companies and organizations in the marketplace can afford the luxury of automation when it comes to developing aerospace machines.

What Types of Tools Are Used in CNC?

The concept of computer numerical control (CNC) incorporates a wide range of machines that perform various functions. These CNC machines are designed with precisely crafted tools to aid in the production process. Here is a basic overview of some common tools that are involved in CNC machining :

CNC Cutting Tools

The majority of CNC machines utilize some types of cutting tools. These tools perform precise cuts on metal, wood, steel, aluminum, and a variety of other materials. Multi-axis cutting tools can move in many directions, enabling the most precise cuts possible on the materials at-hand. Plasma cutting tools and water jet cutting tools offer unique ways to cut materials that are different from the traditional sharp-ended cutter. These tools use plasma and water to cut through a desired material, which can be extremely effective in certain cases.

CNC Drilling Tools

Drill bits and other drilling tools allow CNC machines to drill through any type of material that a user wants to manipulate. Drilling tools can be very high-powered, which allows a machine to drill through most materials of any size and thickness. For instance, if you’re looking to drill 4 holes in a slab of metal, this can be done quite easily with CNC drilling tools.

CNC Router Bits

CNC router bits are the cutting implement that are found at the end of a spindle on a CNC router. CNC router bits have the capability to cut materials like aluminum, brass, copper, and a variety of non-ferrous metals. They can also cut fiberglass, plastic, PVC, tiles, and wood.


Some CNC machining processes use electrical discharges to manipulate materials. The desired shape of a material can be obtained by using electrical discharges – or sparks. Wires within a CNC electrical discharge machine are designed to produce these sparks. The unnecessary material can be removed from a work piece using a series of rapid current discharges that occur between two electrodes. These electrodes are separated by a dielectric liquid, and they endure an electric voltage to obtain the desired effect on the material at-hand.

The Vast Array of CNC Tools

Thanks to technological advancements, there are so many different kinds of both CNC machines and, in turn, CNC tools. These tools are made with extreme precision to work at certain angles – and with specific overall intentions in terms of manipulating a piece of material. With a CNC machine that is equipped with all the right tools, nearly any kind of production can be performed with the utmost precision because of the computer programming that is the driving force behind how these tools function.
