What are the three organic combinations of CNC lathe processing?

Now there are many kinds of CNC systems in the world, with different methods, and their composition and structure have their own characteristics. These structural features are derived from the basic requirements of the initial planning of the system and the ideas of engineering planning.　　 For example, there are completely different requirements for the point control system and the continuous trajectory control system. There is also a big difference between the T system and the M system. The former is suitable for the processing of rotating parts, and the latter is suitable for the processing of special-shaped non-rotating parts.　　For different manufacturers, based on historical development factors and the influence of complex factors that vary from place to place, they may also have their own advantages in planning ideas. For example, the Dynapath system in the United States uses a small board structure to facilitate board replacement and sensitive combination, while the Japanese FANUC system tends to be a large board structure, which is conducive to the reliability of the system's operation and promotes the continuous improvement of the uniform failure rate of the system. But no matter what kind of system, their basic principles and composition are very similar.　　 Generally, the entire numerical control system consists of three parts, namely the control system, the servo system and the orientation measurement system. The control system performs interpolation operations according to the workpiece program, and announces the control instructions to the servo drive system; the servo drive system amplifies the control instructions, and the servo motor drives the machine to move as required; the measurement system detects the direction or speed of the machine's movement and feeds it back to the control System to correct control instructions.
