A leadscrew coupled directly to a dc servomotor is used to drive one of the table axes of an NC milling machine. The leadscrew has 5 threads/in. The optical encoder attached to the leadscrew emits 100 pulses/rev of the leadscrew. The motor rotates at a maximum speed of 800 rev/min. Determine: The control resolution of the system, expressed in linear travel distance of the table axis; the frequency of the pulse train emitted by the optical encoder when the servomotor operates at maximum speed; and the travel speed of the table at the maximum rpm of the motor.
