Question: One axis of an NC positioning system is driven by a stepping motor. The motor is connected to a lead screw whose pitch is 4.0

One axis of an NC positioning system is driven by a stepping motor. The motor is connected to a lead screw whose pitch is 4.0 mm, and the lead screw drives the table. Control resolution for the table is specified as 0.015 mm. Determine
(a) The number of step angles required to achieve the specified control resolution,
(b) Size of each step angle in the motor, and
(c) Linear travel rate of the motor at a pulse frequency of 200 pulses per second.
