A leadscrew coupled directly to a dc servomotor is used to drive one of the table axes of an NC
\r\nmilling machine. The leadscrew has 5 threads/in. The optical encoder attached to the leadscrew
\r\nemits 100 pulses/rev of the leadscrew. The motor rotates at a maximum speed of 800 rev/min.
\r\nDetermine (a) the control resolution of the system, expressed in linear travel distance of the table
\r\naxis; (b) the frequency of the pulse train emitted by the optical encoder when the servomotor
\r\noperates at maximum speed; and (c) the travel speed of the table at the maximum rpm of the motor.
