GATE Mechanical 2014 Set 4 | Question: 23
Better surface finish is obtained with a large rake angle because the area of shear plane decreases resulting in the decrease in shear force and cutting force the tool becomes thinner and the cutting force is reduced less heat is accumulated in the cutting zone the friction between the chip and the tool is less
