5 Axis CNC Router

The application of 5-axis machining technology in production!

With the development of science and technology, 5-axis machining technology is widely used in machining. This paper takes the actual mold parts processing as an example to analyze the feasibility and importance of 5-axis machining technology in mold machining. Compared with the three-axis machining technology, it is known that the 5-axis machining technology can improve the machining efficiency and the quality of the parts, and reduce the number of electrodes, which helps the mold processing enterprises to fully apply the 5-axis machining technology, improve product quality and shorten the product. Production cycle.

Advantages of 5-axis machining technology

5-axis machining technology can quickly enhance the machining efficiency in mold manufacturing and processing, which is generally reflected in the following points:

  1. Clamping parts at one time can complete most of the processing;
  2. The local area has high machining accuracy and short machining time;
  3. With the reduction of difficult-to-machine parts, the number of electrodes is reduced, and the mold production cycle is shortened.

Therefore, before programming, the shape and processing technology of each part of the part should be analyzed to ensure the selection and placement of the part tool, and reduce the secondary clamping and secondary processing. The three-dimensional drawing of the air conditioner skeleton mold part is also a typical part processed by 5-axis machining technology in mold production. 5-axis machining technology can perform multiple jobs at the same time by changing the cutting tool and changing the swing angle of the tool or workpiece in the process of clamping parts at one time. In the contact between the tool and the workpiece, the cutting is carried out in the high-speed rotation of the tool, so as to achieve the desired cutting effect.

The contact angle between the tool and the surface of the workpiece to be machined is different, and the cutting principle is also different, and the final cutting quality is naturally different. In the plane smooth cutting and side cutting, the workpiece and the cutting tool are in a form of surface contact. Compared with point contact, the processing quality and efficiency are better, which effectively reduces the workload of the surface polishing process of the parts. In the process of using three-axis machining, the “slope” machining method is generally selected, so that there is only one contact point between the ball cutter and the surface of the part, which cannot guarantee the machining efficiency, and there is a “residual height” between the two tool paths. Polishing at work has a lot of work to do.

In the same area, 5-axis machining is used. After positioning, the surface to be machined and the tool axis are kept in a vertical state. Using the cutting method of the flat wide knife, the tool and the workpiece are in surface contact, which not only obtains high machining efficiency , it also prolongs the service life of the tool, and there will be no “residual height” between the tool paths, and a higher surface quality can be obtained; in addition, by replacing the tool and using the precision of the machine tool, part of the fine boring and grinding can be completed. , polishing and other processes, only simple polishing is required in the follow-up work.


In the process of injection molding, it is often encountered in the form of cavity processing at the fillet of the molded plastic part. This situation is called “cleaning the root” in the processing process. In the process of root cleaning, the tool is selected according to the radius of the fillet of the part, but under the limitation of the aspect ratio, the length of the tool is also limited, and the three-axis machining of many deep cavity fillets cannot be processed in time. Use electrode cleaning for processing. The test results show that after using the 5-axis machining technology to clear the root, the machining procedure is simplified, the mold production period is shortened, and the tool utilization efficiency is improved.


Under normal circumstances, there will be many unexpected situations in the machining of the tool and the workpiece, and the relative motion of the two cannot be imagined. In order to ensure the stability of the program, 5-axis machining programming should be simulated to avoid other problems during machining. At present, various softwares such as NX6.0 and VERICUT can perform high-precision simulation of 5-axis machining, call models such as tools, machine tools and parts, effectively read program information, and ensure the mutual movement of workpieces and tools, so that The cutting process is simulated in the form of 3D animation. At the same time, it can also detect the overcut of each part.


Under the simulation, programmers can find out the problems in the machining in time when they see the real machining process, so as to ensure the rationality of the 5-axis machining programming. Compared with three-axis machining, 5-axis machining has two more degrees of freedom, and because of this, the requirements for machine tool performance are much higher. In programming, various information about the application of 5-axis machining technology should be considered well. After the parts to be machined meet the machining conditions, the corresponding machine tool should be selected, and the clamping form should be clarified in combination with the machine tool performance.
