The worktable in an NC positioning system is driven by a lead screw with a 4 mm pitch. The lead screw is powered by a stepping motor which has 250 step angles. The worktable is programmed to move a distance of 100 mm from its present position at a travel speed of 300 mm/min.
(a) How many pulses are required to move the table the specified distance?
(b) What is the required motor speed and
(c) Pulse rate to achieve the desired table speed?
