One axis of the worktable in a cnc positioning system is driven by a ball screw with a 7.5-mm pitch. the screw is powered by a stepper motor which has 120 step angles using a 5) 1.8 2: 1 gear reduction (two turns of the motor for each turn of the ball screw). the worktable is programmed to move a distance of 350 mm from its present position at a travel speed of 1,000 0 mm/min.(a) how many pulses are required to move the table the specified distance? (b) what is the required motor rotational speed and (c) pulse rate to achieve the desired table speed?
