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

The end of a large tubular workpart is to be faced on a NC vertical boring mill.
The part has an outside diameter of 38.0 in and an inside diameter of 24.0
in. If the facing operation is performed at a rotational speed of 40.0 rev/min,
feed of 0.015 in/rev, and depth of cut of 0.180 in, determine (a) the cutting
time to complete the facing operation and the cutting speeds and metal
removal rates at the beginning and end of the cut.
