Question: Solve previous Problem, only the servomotor is connected to the leadscrew through a gear box whose reduction ratio = 10:1 (10 revolutions of the motor for each revolution of the leadscrew).
Problem: A leadscrew coupled directly to a de servomotor is used to drive one of the table axes of an NC milling machine. The leadscrew has 2.5 threads/cm. 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
(a) the control resolution of the system, expressed in linear travel distance of the table axis;
(b) the frequency of the pulse train emitted by the optical encoder when the servomotor operates at maximum speed; and
(c) the travel speed of the table at maximum motor speed.
