An aluminum hollow shaft 200 mm outside diameter, 100 mm inside diameter and 500 mm length from lathe chuck is to be face turned at the end. Its end face is finished at a rotational speed of 400 rpm using a feed rate of 0.25 mm/rev. The side cutting edge angle or lead angle of the tool is 300 . How much cutting time and maximum power is needed to finish the facing operation with a 4 mm depth of cut. What is likely to be a perpendicularity error in this operation? Specific cutting energy = 0.025 W/ mm3 /min and E = 50 kN/mm2

An aluminum hollow shaft 200 mm outside diameter, 100 mm inside diameter and 500
mm length from lathe chuck is to be face turned at the end. Its end face is finished at a
rotational speed of 400 rpm using a feed rate of 0.25 mm/rev. The side cutting edge angle
or lead angle of the tool is 300
. How much cutting time and maximum power is needed to
finish the facing operation with a 4 mm depth of cut. What is likely to be a
perpendicularity error in this operation? Specific cutting energy = 0.025 W/ mm3
/min and
E = 50 kN/mm2
