Assignment:
A milling operation is performed on an NC machining center. Total travel distance = 300 mm in a direction parallel to one of the axes of the worktable. Cutting speed = 1.25 m/sec and chip load = 0.05 mm. The end milling cutler has four teeth and its diameter = 20.1) mm. The axis uses a de servomotor whose output shaft is coupled to a leadscrew with pitch = 6.0 mm. The feedback sensing device is an optical encoder that emits 250 pulses per revolution. Determine (a) the feed rate and time to complete the cut, (b) the rotational speed of the motor, and (c) the pulse rate of the encoder at the feed rate indicated.
Provide complete and step by step solution for the question and show calculations and use formulas.
