Question: In Problem 7.3, the axis corresponding to the feed rate uses a dc servomotor as the drive unit and an optical encoder as the feedback

In Problem 7.3, the axis corresponding to the feed rate uses a dc servomotor as the drive unit and an optical encoder as the feedback sensing device. The motor is geared to the lead screw with a 10:1 reduction (10 turns of the motor for each turn of the lead screw). If the lead screw pitch = 5 mm, and the optical encoder emits 400 pulses per revolution, determine the rotational speed of the motor and the pulse rate of the encoder in order to achieve the feed rate indicated.
