Question 160
If $$\alpha$$ is the rake angle of the cutting tool, $$\psi$$ is the shear angle and $$v$$ is the cutting velocity, then the velocity of chip sliding along the shear plane is given by
1] $$\frac{v \cos \alpha}{\sin(\psi - \alpha)}$$
2] $$\frac{v \sin \alpha}{\sin(\psi - \alpha)}$$
3] $$\frac{v \sin \alpha}{\cos(\psi - \alpha)}$$
4] $$\frac{v \cos \alpha}{\cos(\psi - \alpha)}$$
