Answer:


tan\phi =(r cos\alpha )/(1-r sin\alpha )

Step-by-step explanation:

Chip thickness ratio:

It is the ratio of thickness of chip before cutting the and after cutting .Generally it is denoted by r.Chip thickness ratio depends on several parameter like type of material ,type of toll and many more.

Relationship between shear angle ,rake angle and chip thickness:

Lets take α is the rake angle.

Ф is the shear plan angle.

r is the chip thickness ratio.


tan\phi =(r cos\alpha )/(1-r sin\alpha )
