How Does 5-Axis CNC Machining Work?

Last Updated on October 12, 2023 by assistant

In recent years, whenever people talk about machining concepts, five-axis machining technology comes to mind. Indeed, it is undeniable that one of the more popular and advanced modern CNC machining processes is five-axis CNC machining. However, when people really want to enjoy 5-axis cnc machining services, many people’s first impression is: expensive, high initial cost, higher requirements on operators, etc. However, is this really the case?

With this curiosity in mind, after reading a lot of information and talking to relevant people in the industry, we will provide you with the answer to this question and other important information about this processing.

What is Five-Axis CNC Machining?

Before understanding how 5-axis CNC machining works, if you are new to 5-axis CNC machining, in my previous article I mentioned some basics and its advantages. Of course, to avoid trouble, I will explain it to you in detail in this article.

The so-called five-axis means that in addition to the traditional 3-axis X, Y, and Z axes, the machine tool used for five-axis machining also adds two other axes, one of which rotates along the X-axis, which we call the A-axis or the Four axes, the other rotates around the Y axis, which we call the B axis or the fifth axis. The processing process of machine tool equipment composed of these five axes is called five-axis CNC machining. After adding additional bearings, the types of work that CNC machine equipment can undertake will be more diverse, and the level of cutting details will be greatly improved.


5-Axis CNC Machining Principle

In fact, as long as it involves CNC processing, he cannot do without CNC program-G code. Normally, our first step is to convert the part project file (CAD design file) you want to make into the corresponding CAM. CAM (computer-aided manufacturing) is a software used to manage, control and operate the production equipment process. It There are two parts of information: input information and output information. The input information refers to the design process route of the part and the content of the workpiece to be processed, and the output information is the movement trajectory and CNC program during processing. It can be said that CAM is an indispensable and important component in generating CNC digital language or G code.

Next, it’s just a matter of uploading the G-code to the 5-axis CNC machine, and then placing the material on the machine for CNC machining. It is worth noting that G code has extraordinary significance. In the entire CNC machining process, the instructions it transmits will affect the tool path of the machine and the correct tools used for processing.

5-Axis CNC Machining Types

Currently, there are two mainstream versions of five-axis CNC machining in the manufacturing market, one is Simultaneous 5-Axis CNC machining, and the other is 3+2-axis machining.

The difference between them is that synchronous five-axis CNC machining will be more advantageous in terms of manufacturing part speed, because it can realize the continuous rotation of the cutting tool along the 5 axes. It does not need to stop to achieve the optimal tool rotation direction, provided that the early stage Once the programming code is written, in terms of operation, synchronous 5-axis CNC machining will be more simple. 3+2-axis machining requires constant stopping and starting of the machine to achieve the best tool direction, but the 3+2-axis also provides the ability to perform milling functions. The two additional bearings can fix the workpiece while maintaining the matching tool. of rotation angle.

In order to let you better understand the working status of five-axis CNC, we have compiled some process videos about five-axis machining parts for you, you can click to watch.

Based on the above description, you should have a general understanding of the five-axis machining process. However, when it comes to five-axis machining, what everyone is most worried about is the price. In fact, regarding price, Ruitai has professional quotation engineers who will carefully analyze and compare your design documents and give you the most favorable manufacturing quotation, so you don’t have to worry too much. Additionally, not every part manufacturing project is suitable for processing on a five-axis synchronous machine. Synchronous 5-axis machine tools can help you handle tighter tolerances to achieve complex geometries, but the startup cost is relatively high, so under the premise of ensuring quality, sometimes 3+2-axis machining is also a good choice.


Five-axis CNC machining is a multi-axis subtractive manufacturing process in which a machine shapes the workpiece material and moves in 5 directions, or perpendiculars. It can help you produce parts faster and shorten the production cycle.
