Abstract:
Computer numerical control machine provide automatic and precise motion control
via special programming language called G-code to its elements such as work table
and tool spindle with the aids of servo motor and the stepper motor.
the operation of the stepper motor depends on the digital signal is sent from the
controller to the motor in the form of pulses as to rotate the motor which is
converted to linear movement by the lead screw, As the distance moved by the
slide and the feed can be accurately controlled by the computer numerical control
machine control system.
Servo motor which we are focused to study, the servo motor requires both
positional and velocity feedback, which means that the actual position and velocity
of the slideway is continuously compared to the digital signal that is being sent out
by the controller.
