It causes
the carriage to travel at 6mm per revolution. 48 steps of the stepper motor rotor
rotation are equal to one full revolution of the shaft. Hence, distance traveled per
step is (6/48) and this equal to 0.125 mm/step. Since the active winding length of
mandrel is set to 700 mm, bump switch is installed to control the carriage motion
only for 700 mm of length. The steps required for the carriage to travel along 700
mm distance is then equal
