Mechanics of Metal Cutting - Manufacturing Technology

Figure 1.21 shows the velocity relationship in orthogonal cutting.

VELOCITY RELATIONSHIP

Figure 1.21 shows the velocity relationship in orthogonal cutting. The various velocities are cutting velocity (V), chip velocity (Vc) and shear velocity (Vs). The chip velocity (Vc) is the velocity of the chip relative to tool and it is directed along the tool face and shear velocity (Vs) is the velocity of chip relative to workpiece which is directed along shear plane.


Substituting 'r' in above equation

Vc = V.r

Similarly, from triangle ODA,


From triangle ODB,


By equating (1.7) and (1.8),
