Classification of CNC machine tools
Open-loop control CNC machine tools: This type of machine without position detection feedback device, usually with the stepper motor as the actuator. Input data through the CNC system operation, issued a pulse command, so that stepper motor through a step angle, and then through
Semi-closed-loop control CNC machine tools: the end of the motor or the end of the screw to install the detection components (such as induction synchronizer or photoelectric encoder
The mechanical transmission mechanism is converted to a straight line movement of the table, and the moving speed and displacement of the moving part are determined by the frequency and the number of pulses of the input pulse.
