Materials Science and Manufacturing Engineering

  1. Better surface finish is obtained with a large rake angle because
    1. the area of shear plane decreases resulting in the decrease in shear force and cutting force
    2. the tool becomes thinner and the cutting force is reduced
    3. less heat is accumulated in the cutting zone
    4. the friction between the chip and the tool is less
Correct Option: A

As rake angle increase shear plane decreases so smaller force one required so smooth machining operation

tan Φ =
r cos α
Favourable machining
1 - r sin α

condition Φ ↑α↑r↑
