The table of a CNC machine is driven by a DC servomotor. A digital encoder which emits 1000 pulses per second is mounted on the lead screw as a feedback device. If the lead screw pitch is 6 mm and motor rotates at 500 rpm, find
1. Basic Length Unit (BLU) of the system.
2. Linear velocity of the table.
3. Frequency of pulses generated by the feedback device.
