Common Data: In an orthogonal machining operation:
Uncut thickness = 0.5mm
Cutting speed =20m/min
Rake angle = 15°
Width of cut = 5mm
Chip thickness = 0.7mm
Thrust force = 200N
Cutting force = 1200N
Assume Merchant's theory.
The Values of shear angle and shear strain, respectively, are
A. 30.3° and 1.98
B. 30.3° and 4.23
C. 40.2° and 2.97
D. 40.2° and 1.65
