There’s no question that computers have had a profound impact on manufacturing. Computer numerical control (CNC) machining is now the dominant technology in the industry. If you’re interested in getting started in CNC machining, there are a few things you need to know.
In this article, we’ll outline the basics of CNC machining and provide an overview of the types of equipment you’ll need to get started. Stay tuned for future articles where we’ll dive into more detail on these topics.
What is a CNC machine, and what can it be used for?
It is a computer-controlled machine that can be used to create prototypes, tools, or parts for production. The three primary axes of a CNC machine are the X, Y, and Z axes. In addition to these axes, most CNC machines have one or more auxiliary axes that can be used for milling, drilling, and tapping.
CNC machines can be used for various applications, including milling, turning, routing, and even 3D printing. Generally, any process that can be automated using traditional methods can also be completed using a CNC machine.
The benefits of CNC machining
There are many benefits to using CNC machining over traditional manufacturing methods. Perhaps the most significant benefit is increased accuracy. CNC machines can produce parts with tolerances as low as 0.001 inches (0.0254 mm). They can also be used to create complex shapes that would be difficult or impossible to produce using traditional methods.

Another benefit of CNC machining is increased efficiency. Once a part has been designed and the program created, the machine can be left to run unattended for hours or even days at a time. It allows manufacturers to increase production without having to increase their workforce.
CNC machining is also very versatile. The same machine can be used to produce a wide variety of different parts. And, if a change needs to be made to the design of a part, it can be easily incorporated into the CNC program.
Finally, CNC machining is relatively low-cost. When compared to other prototyping methods such as 3D printing, CNC machining is very affordable. In addition, the cost of CNC machines has been dropping steadily in recent years, making them even more affordable.
What do you need to get started in CNC machining?
If you’re interested in getting started in CNC machining, you’ll need a few things. First, you’ll need a computer with CAD software installed. There are different types of CAD software available, but we recommend Autodesk Fusion 360 because it’s straightforward to use and provides a wide range of features. Once you have CAD software, you’ll need to create a design for your part.

Once you have a design, you’ll need to create a CNC program. It can be done using CAM software such as Autodesk HSMWorks or Fusion 360. If you’re unfamiliar with CAM software, we recommend checking out our tutorial on creating CNC programs.
Finally, you’ll need a CNC machine. Many types and sizes of CNC machines are available on the market. In general, the size of the machine will be determined by the size of the parts you want to produce. For smaller parts, a desktop CNC machine may be sufficient. For more significant parts, you’ll need an industrial-sized machine.
What are the different types available on the market today?
The two most common types of CNC machines are milling machines and lathes. Milling machines create parts with complex shapes, such as gears, while lathes produce parts with cylindrical shapes, such as shafts. In addition to these two types of machines, hybrid machines combine the features of both milling machines and lathes.
Milling machines can be further divided into horizontal milling machines and vertical milling machines. Horizontal milling machines have a spindle parallel to the table, while vertical milling machines have a spindle perpendicular to the table.
There are also a variety of specialized CNC machines available on the market, such as those designed for engraving, routing, or plasma cutting. No matter what type you choose, select one that is durable and has a good reputation. It will ensure that your machine will last for many years and will be able to produce high-quality parts.
What tools and software do you need to start CNC machining, and where can you find them online or in stores?
To start CNC machining, you’ll need a computer with CAD software installed. We recommend Autodesk Fusion 360 because it’s easy to use and provides a wide range of features. Once you have CAD software, you’ll need to create a design for your part.
Once you have a design, you’ll need to create a CNC program. It can be done using CAM software such as Autodesk HSMWorks or Fusion 360. If you’re unfamiliar with CAM software, we recommend checking out our tutorial on creating CNC programs.
Finally, you’ll need a CNC machine. Many types and sizes of CNC machines are available on the market, like a 4×4 CNC router. In general, the size of the machine will be determined by the size of the parts you want to produce. For smaller parts, a desktop CNC machine may be sufficient. For more significant parts, you’ll need an industrial-sized machine.
You can find all the tools and software you need to start CNC machining online or in stores that sell computer numerical control (CNC) equipment. Once you have the necessary tools and software, you’ll be ready to start producing high-quality parts using CNC machining.
