3. (20 points) A part is to be face milled on a CNC machine. The cutter has 6 teeth and its diameter is 50 mm. Cutting speed is 90 m/min and feed is 0.1 mm/tooth. In order to program the machine tool, using these values calculate the machining conditions in terms of (a) (10 pts.) Spindle speed N in rev/min (rpm) (b) (10 pts.) Feedrate in mm/min.
