CNC Knowledge: What is the real five axes? What is a false axis at five axes? What is the difference compared to the three axes?

With the rise of the automotive industry, more and more five-axis CNC machine tools are available. However, on the current market, there are few real five-axis machine tools (with RTCP function), and many false five axes (only for the indexing function). What is the real five -axis axis, what is the false axis at five, and what is the difference between it and the three axes? The following is explained as follows.

The real axis five has an RTCP function. It can be automatically converted on the basis of the length of the pin pendulum and mechanical coordinates of the rotary table. When preparing the program, you only have to consider the coordinates of the part and you do not need to consider the length of the pendulum of the pin and the position of the rotary table.

Whether it is a real five -axis axis does not depend on whether the five axes are linked, but the five axes of false can also be linked. If the pin has a real five -axis algorithm. It is a question of doing the indexing treatment. The fake axis at five has a lot of problems.

A CNC system with the RTCP function can be programmed directly using the tip of the tool without considering the central distance of the rotation axis. After applying the RTCP mode, programming 5 The treatment of coordinates can directly target the tip of the tool instead of the center of the rotary spit, programming will therefore become much simpler and more efficient.

According to the figure, we can see that for the double platform of False five axes, several coordinates must be defined to achieve the purpose of the indexing of treatment. However, if it is a five -axis swing head type, the indexing treatment cannot be finished, because the five -axis swing head is not a separate Z movement during treatment Down, but Z and X or Y. At present, the programming of false axis at five years will be very annoying and the debugging will be more difficult.
