Cutting speed in meter/minute= goiner (8).pdf Type here to search TCLAn end milling operation is carried out along a straight line path that is 325 mm long. The cut is in a direction parallel to the x‑axis on a CNC machining center. Cutting speed = 30 m/min, and chip load = 0.06 mm. The end milling cutter has two teeth and its diameter = 16.0 mm. The x‑axis uses a DC servomotor connected directly to a leadscrew whose pitch = 6.0 mm. The optical encoder emits 400 pulses per revolution of the screw. Determine (a) feed rate during the cut, (b) rotational speed of the motor, and (c) pulse rate of the encoder at the feed rate indicated.
