An numerical control (NC) worktable operates by closed-loop positioning. The system is shown below. The lead screw has a pitch of 6mm and is coupled to the motor shaft with a gear rati 5:1(five turns of drive motor for each turn of the screw). The optical encoder generates 48 pulses/rev of its output shaft. The table is programmed to move a distance of 250mm at a feed s rate = 500mm/min. Determine: a) How many pulses should be received by the control system to verify that the table has moved exactly 250mm. (Ans:2000 pulses) b) The pulse rate of the encoder.(Ans:66.667HZ) c)The drive motor speed that correspond to the specified feed rate.(Ans:416.667rev/min)
