What Is The CNC Milling Procedure Overview?

by Alexander J.

Technological evolution has made manufacturing a straightforward process. CNC milling is one technological development process that has made the precision of milled parts possible. 

Due to technology, CNC produces parts that are high-quality and efficient. Also, the software used requires little maintenance. Generally, a CNC milling machine does not require much on the maintenance side. The only service required is some light cleaning and changing the cutting implements at the appropriate time. CNC milling machines can develop any component you desire. At china cnc milling service, you will find the best CNC milling service in the market. This article aims at giving you a brief overview of the CNC milling procedure.

Best use for CNC milling

  • Drilling and cutting in manufacturing
  • Shaping materials such as plastics and metal

A brief overview of the CNC milling procedure

1. Designing a CAD model

The first step in the CNC milling procedure is the design of a CAD model. At the beginning of the CNC milling process, 3D or 2D part formats are created.

2. Converting a CAD model into a CNC program

After creating the 3D or 2D part model, the design is transmitted to a CNC-compatible file format. The CAM software converts the exported CNC compatible file format into a CNC machine program. The CNC machine program directs the machine’s actions. It also directs the movement of the tools over the workpiece.

3. CNC milling machine preparation

The technician responsible has to first set up the CNC milling machine before running the CNC program. To prepare the CNC milling machine, the technician fixes the workpiece to the machine’s work table or surface. He can also opt to withhold the device. In addition, he attaches the machine milling tools to the spindle.

4. Carrying out the milling operation

The CNC milling procedure uses vertical or horizontal authorized milling machines depending on the; requirements and specifications of the milling applications and revolving multi-point tools (an example is drills and mills). When the CNC milling machine is good to go, the technician initiates the CNC machine program through the machine interface, causing the milling machine to carry out the milling process.

5. CNC milling procedure

After the CNC milling process is executed, the machine will rotate therefore cutting tools. The speed used by the machine for cutting can go up to thousands of RPM. The machine will supply the workpiece into the fixed revolving tool. Then pass the tool over the fixed workpiece, and lastly, move the workpiece and tool in tandem to one another. The CNC milling procedure will help get the required workpiece cuts.

Types of CNC milling services

  • Form milling: Cuts flat and curved surfaces
  • Plain milling: Creates horizontal and flat surfaces
  • Face milling: Creates contours and flat surfaces
  • Angular milling: The milling process is used on flat surfaces that are neither perpendicular nor parallel to the cutting tool axis.


CNC milling is the most popular CNC service. It is primarily available in 3 to 4 axes, but you can also find it on five axes; therefore, performing the XYZ axis. The milling process has advanced in recent years to CNC milling. CNC milling is a computer-controlled process that allows for automatic production processes.
