Now, most manufacturing industries are switching from conventional machines to computer-numerical control (CNC) machining. Machines that were once controlled by experienced engineers like shapers, center lathes, router, and millers are now fully operation without human intervening.


The shift towards the CNC machines by many different types of industrial companies is due to appealing benefits CNC machines offer in aspects of fabrication and manufacturing applications. When using any of CNC machines to work on your industrial projects you are guaranteed efficiency, precision, accuracy and speed. These benefits are what manually-operated machines like the router, grinder, center lather, shaping machines etc. do not offer.

Furthermore, in terms of finance and production, CNC gives an edge over the conventional machines. For instance, in an industry with about 20 center lathe machine, there must be an experienced technician for each one of the – 20 technicians. However, with over 20 Computer-numerical control lathe machine, a skilled and well-experienced operator is enough to handle all at the same time.

There are many industries which require machines to be more precise, consistent and able to make complex cuts. A few of these industries are listed below:

  • Agriculture
  • Electronics
  • Automotive
  • Dental
  • Firearms
  • Aerospace
  • Hospitality
  • Production
  • Military
  • Metalworks
  • Publishing
  • Transportation
  • All types of manufacturing industry.

The U.S. Air force mechanics was the first department to successfully produce computer-numerical control machines in the 1940s.

The U.S. Air force mechanics designed the first CNC to be operated using the paper-punched technology, which as of today has been modified into a digital software.

These machines arose to fame among many industrial companies due to its ability to provide a high level of precision of many quantities in the various field. Since the CNC makes use of programming language, it was able to provide the manufacturing companies with detailed, consistent result.

Recently, there have been many misconceptions and questions about CNC machines. Below are answers that help explain them better.

Q1 – What are CNC Machines?

When it comes to manufacturing machined parts, products or items, CNC machines are responsible for the primary process. What helps manufacturers achieve high numbers and topnotch quality is the Computer-numerical control machine.

CNC machines do not make use machine tools (center lathes, routers, mills or shaping machines) but a system called Computer Numerical Control. The software is quite different from our phones or PCs software. This software was specifically designed to control the CNC machines, using a program called G-Code. It is a particular and unique code that gives operators the chance total control the CNC attributes: speed, location, coordination, and feed rates.

The customized program, G-Code, is infused with a software which is set up on a computer with a sophisticated look. You do not require many technicians to operate your machines. You can have all the CNC machines all controlled by the computer console unit. These machines are automated and computerized which makes them efficient to meet your target, perform the certain action even well-experienced technician wouldn’t be able to achieve efficiently.

Due to advancement in technology, more metal and plastic parts with more complexity are being needed in a very large amount, therefore, manufacturing industries are left with no choice but to rely on CNC machines to help out. Now, companies make use the benefit of a CNC having many axes that can be operated to form complex, difficult angles to produce well-designed metal, wood or plastic parts, and products.

Q2 – which is Preferable: CNC Machine or Conventional?

Either you make use of a CNC machine or a conventional machine, we desire to have our end product perfectly made out of the raw piece of the workpiece. Although both works to provide you with the desired end parts, they still have advantages over each other. A comparison is a manual machine versus an automated machine. Automated machines are known to provide incredible advantages over the conventional, manual machines: speed, precision, yield ratio, efficiency, accuracy, and production rate.

Using a computer-numerical-control machine requires commanding the machine using the g-code to perform the task. While, the conventional machine requires you to follow all the required steps (like setting up the tools, following the precautions and many more) in performing the given action. In manual machines, technicians must be aware of how to set the gears which it’s not needed in CNC because it doesn’t utilize any.

In addition, when it comes to price, manual, machines are known to be cheaper and affordable than any computer-numerical control machine. CNC machining is mainly of benefit if you are dealing with high quantities which makes it worth the price. However, it is unfavorable for industries with a smaller output.

Also, when dealing with CNC machining, it is important that you know how to use computer-aided design (CAD) software to produce a model for the computer-numerical control machine either in 2D or 3D. The prototype designed using CAD is then fed into the software in the console unit, which helps the machine produce an exact product as the prototype feed into it.

It also as a memory where this prototypes are stored and can easily be called up whenever you need to reproduce such part.

Both conventional and CNC machine can use the following materials:

  • Aluminum
  • Brass
  • Copper
  • Foam
  • Fiberglass
  • Plastic
  • Polypropylene
  • Steel
  • Titanium
  • Wood

However, there are about 20 cutting cores CNC machines offer you with great precision:

  • Contour
  • Bore
  • Thread
  • Cut
  • Drill
  • Face
  • Grind
  • Lathe
  • Punch
  • Mill
  • Stamp
  • Tap
  • Texture
  • Turn
  • Weld
  • Shape
  • Knurl
  • Shear

Although this list is short, you can understand why lots of manufacturing companies are going for computer-numerical control machines rather than the old, conventional, manual machines.

Advantages of CNC Machining

If you deal with the production of metal parts and components then you should be aware of it clear benefits.

  • Eliminate human error
  • Helps attain accuracy
  • High production and scalability
  • More capability
  • Reliable endurance
  • Less labor
  • Uniform products
  • Helps saves costs
  • Lesser headaches
  • Safer
  • Design retention
  • Low maintenance
  • Versatility
