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.
