Assuming that the coefficient of friction in cutting is 025

Assuming that the coefficient of friction in cutting is 0.25 for turning a hard aluminium alloy on a 20 hp lathe (mechanical efficiency = 90%) with a width of cut of 0.24 in, a rake angle of 11°, and a cutting speed of 333 ft/min. Assume the cut is at maximum depth and feed. Aluminium 1199-H18 has shear strength of 10.9 ksi.

Calculate:

1. Shear angle, phi

2. Cutting Force, Fc

3. Thrust Force, Ft

4. Friction Force, F

5. Shear Force, Fs

6. Area of Shear, As, and feed
