The y-axis of an x-y positioning table is driven by a stepping motor that is connected to a leadscrew with a 3:1 gear reduction. The stepping motor has PPR=72 pulse/rev. The leadscrew has a pitch 0.2 in/rev and provides an axis range = 30 in. Determine (a) the required rotational speed of the y-axis stepping motor and (b) the corresponding pulse train frequency to drive the table in a straight line (incremental positioning) from point (20,25) inch to point (4.5,7.5) inch in exactly 30 sec (0.5min).. Ignore acceleration.

The two axes of an x-y positioning table are each driven by a stepping motor connected to a leadscrew with a 10:1 gear reduction. The step angle on each stepping motor is 7.5°. Each leadscrew has a pitch = 5 mm/rev and provides an axis range = 300 mm.

A NC machine tool table is powered by a servomotor, lead screw, and optical encoder. The lead screw has a pitch = 5.0 mm and is connected to the motor shaft with a gear ratio of 16:1 (16 turns of the motor for each turn of the lead screw). The optical encoder is connected directly to the lead screw and generates 200 pulses/rev of the lead screw. The table must move a distance = 100 mm at a feed rate = 500 mm/min. Determine (a) the pulse count received by the control system to verify that the table has moved exactly 100 mm; and (b) the pulse rate and (c) motor speed that correspond to the feed rate of 500 mm/min. Solve the problem assuming the optical encoder is directly coupled to the motor shaft rather than to the lead screw.
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
