CNC Machining: How Does It Work?

The incredible revolution in the manufacturing industry has allowed firms to create products with high-level precision. One such revolutionary process is the CNC machining process. CNC stands for Computer Numerical Control, and it uses numerical codes to generate complex products.

Here’s everything you need to know about it.

A Brief History

Before CNC was introduced, machines only used numerical control to generate products. The process of numerical control used punched tapes to send codes to the machine to ensure smooth production. The machine code had to be manually punched into the tape and then attach to the motors to create products. This process was highly time-consuming and unproductive. The introduction of CNC was a massive upgrade from the Numerical Control (NC) procedure.

How Do CNC Machines Work?

CNC machining begins with designing the product and then programming into the CAD software. The designs of the product are made in both 2D and 3D to ensure maximum accuracy. The 3D model designed in the software provides the machine with accurate measurements of the final prototype that needs to be produced. Once the data is transferred into the machine, the cutting speed and voltage need to be set. Once everything is in order, you’ll have your final product ready.

Types Of CNC Machining

CNC machining can conduct different types of processes. The variety in processes can help you create various products. Here are some of the common types.


CNC milling is the process where the cutting tool attached with the CNC machine rotates to cut the object and shape it into the specific product you need. Milling provides excellent precision and is also a quick method to generate prototypes.


CNC turning is quite different from milling. During CNC turning, the material is rotated while the cutting tool doesn’t move. The rotating material leans toward the stationary cutting tool to create the product. CNC turning is used to create shafts, and it also ensures high accuracy.


While both milling and turning can produce holes through cutting, CNC drilling is the recommended process to create a hole. CNC drilling rotates the tip of the drill at high speeds to ensure smooth and precise drilling.

Applications of CNC Machining

CNC machining is gaining popularity due to its vast applications. CNC machines can have three to five axis, which can increase your production’s flexibility. CNC machining up until now has been successfully used in several industries, including aerospace, consumer foods, mining, transportation, and many others.
