CNC milling is behind a multitude of products, ranging from smartphones all to supersonic jets. It's also a perfect technique for producing in large quantities and for rapid prototyping. Due to its unparalleled versatility and reliability, CNC Milling has become a staple of modern day manufacturing. What specifically is CNC Milling and how does it function?

What is CNC Milling?

CNC Milling involves using a cutting machine that is mounted on a rotating spindle to selectively remove material from a dedicated workpiece. The raw material is anchored to a table that can rotate or move along different planes that allow the tool to work at a variety of angles.

The method of HAAS mini mill can be utilized to produce not only creating shapes but also slots, holes, notches and pockets. As the process progresses the edges of the cutter create several quick cuts to shape the surface of the material.

CNC Milling: The Process

The CNC milling process begins by importing the manufacturing instructions into the computer-aided design (CAD) system. This can be in either a 2D or 3D format. Once the process is complete the designs are then converted into a machine-readable format which is exported to the CNC machine. The machine then relays the instructions to different tools to recreate the design using the selected material. If you are looking for machine shop, DieSand is the right spot to go.

Before starting the process, the machine must be fitted with the correct equipment and the raw material needs to be secured using the help of a vice. After the preparations are finished then the operator can launch the program via the interface of the machine.

The tools spin at thousands RPM once the CNC Milling process starts. This allows them to quickly cut through the material. To mold the material according to your specifications, the table will be able to rotate on several axes.

Types of CNC Milling

There are four major kinds of milling that are:


This method is also referred to as surface or slab milling. It involves using a cutting tool that has a rotary axis which is parallel to the surface. The tool is employed to make flat surfaces.


This is due to the axis being perpendicular to the material's surface. This method uses tools that have more teeth than in plain milling. The teeth at the edges of tools are utilized to cut the raw materials. While the ones that are in contact with the flat material are used to finish.


As the name suggests this type of CNC Milling involves the tool's rotary Axis being in a slant to the surface of the raw material. The machines are a middle ground between Plain and Face Milling.

Form milling

This method of milling creates components that do not have flat surfaces. The machine can be fitted using a variety of different tools, depending on the type and size of the curve.

What can CNC Milling be used For?

The versatility of CNC Milling allows it to be utilized in many different ways. While the process may be more commonly associated with car parts and aerospace components, it can also be utilized for other reasons, including:
