A dc servomotor drives the x-axis of a CNC milling machine table. The motor is coupled to a ball screw, whose pitch = 7.5 mm, using a gear reduction of 8:1 (eight turns of the motor to one turn of the ball screw). An optical encoder is connected to the ball screw. The optical encoder emits 75 pulses per revolution. To execute a certain programmed instruction, the table must move from point (x = 202.5 mm, y = 35.0 mm) to point (x = 25.0 mm, y = 250.0 mm) in a straight-line path at a feed rate = 300 mm/min. Determine (a) the control resolution of the system for the x-axis, (b) rotational speed of the motor, and (c) frequency of the pulse train emitted by the optical encoder at the desired feed rate, (d) How many pulses are emitted by the x-axis encoder during the move.
