In orthogonal machining operation, the chip thickness and the uncut chip thickness are equal to 0.45 mm. If the tool rake and is 0 deg. The shear plane angle is
-
- 45°
- 30°
- 18°
- 60°
- 45°
Correct Option: A
| r = | = | = 1 | ||
| Chip thickness after the metal is cut | 0.45 |
If α = shear plane angle and α = rake angle = 0°
| then tanφ = | = | = 1 or φ = 45° | ||
| 1 - rsinα | 1 - 1.sin0° |
