What is CNC Milling And How Does It Work?

CNC milling is a type of machining that uses computer numerical control. This machine type includes computer-operated machines that can create highly complex, intricate shapes by turning each axis on and off individually to create 3D objects in the form of parts or complete products. Learn how this technology works and what it does!

What is CNC milling?


CNC milling is a technique used in manufacturing and is the process of machining parts using a computer-controlled lathe or CNC machine. The advantage of using CNC milling compared to traditional machining methods is the production of very dimensionally accurate parts.


Milling is suitable for many different features, including threads, chamfers, grooves, and more. This makes it possible to generate complex designs using a variety of different milling operations: face milling, face milling, angle milling, form milling, contour milling, gear milling, etc.


How does it work?


The process begins by designing the part on a computer, transferring the design to a CNC machine, and then programming it to make the necessary movements. Once the machine is set up, it will start cutting parts from the original design. The accuracy of the milling process depends on the quality of the software and design used to create the part.


When using a CNC milling machine, many factors affect the accuracy and quality of the finished product. First, the accuracy of CAD data is critical. This data must be precise enough to be transferred to the machine without any additional modification. Second, the quality of the cutting tool is critical. If the tool is inaccurate or malfunctioning, your results will be poor. Lastly, you need good machining skills to create good toolpaths on the computer and make sure they can work efficiently.




CNC milling is the process of manufacturing parts using a variety of materials. It involves machines that make precise cuts in metal or other materials using an array of cutting tools. If you are interested in this service then please contact AS PRECISION for more information on CNC milling.
