In Douyin, there is a video BGM of characters running and the background of their own travel changing (the one with two girls and one with orange hair being pulled is this BGM)

1. Open-loop control CNC machine tools

This type of machine tool does not have a position detection feedback device, and usually uses a stepper motor as the actuator. The input data is calculated by the CNC system and a pulse command is issued to cause the stepper motor to rotate through a step angle, and then converted into linear movement of the worktable through the mechanical transmission mechanism. The moving speed and displacement of the moving parts are determined by the frequency and displacement of the input pulse. Determined by the number of pulses.

2. Semi-closed loop control CNC machine tool

Install a detection element at the end of the motor or the end of the screw, and indirectly detect the displacement of the moving part by detecting its rotation angle, and then provide feedback into the CNC system. Since most of the mechanical transmission links are not included in the closed loop of the system, more stable control characteristics can be obtained. Although its control accuracy is not as good as closed-loop control CNC machine tools, it is more convenient to debug, so it is widely used.

3. Closed-loop control CNC machine tools

This type of CNC machine tool has a position detection feedback device. The position detection feedback device uses linear displacement detection components and is directly installed on the moving parts of the machine tool. , the measurement results are directly fed back to the CNC device. Through feedback, the transmission error in the entire mechanical transmission chain from the motor to the moving parts of the machine tool can be eliminated, and ultimately accurate positioning can be achieved. 1.
