Question

Stepper motors are used to drive the two axes of a component placement machine used for electronic assembly. A printed circuit board is mounted on the table. It must be positioned accurately for the reliable insertion of components into the board. Range of each axis = 600 mm. The lead screw used to drive each of the two axes has a pitch of 0.4 cm. The inherent mechanical errors in table positioning can be characterized by a Normal distribution with a standard deviation = 0.00045 cm. If the required accuracy for the table is 0.032 mm, determine the number of step angles that the stepper motor must have.
