A DC servomotor drives the y-axis of a NC milling machine table. The motor is coupled to the table lead screw with a gear reduction of 2:1. The lead screw pitch =5 mm/rev. An optical encoder is directly connected to the lead screw. The optical encoder emits 100 pulse/rev. To execute a certain programmed instruction, the table must move from point (25,28)mm to point (155,275)mm in a straight-line trajectory at a feed rate = 200 mm/min. For the y-axis only, determine: (a) rotational speed of the motor, and (c) frequency of the pulse train emitted by the optical encoder at the desired feed rate

Question
A DC servomotor drives the y-axis of a NC milling machine table. The motor is
coupled to the table lead screw with a gear reduction of 2:1. The lead screw pitch =5
mm/rev. An optical encoder is directly connected to the lead screw. The optical
encoder emits 100 pulse/rev. To execute a certain programmed instruction, the table
must move from point (25,28)mm to point (155,275)mm in a straight-line trajectory
at a feed rate = 200 mm/min. For the y-axis only, determine: (a) rotational speed of
the motor, and (c) frequency of the pulse train emitted by the optical encoder at the
desired feed rate
