Mechanics of Metal Cutting - Manufacturing Technology
The energy consumed per unit time is given by the equation
POWER AND ENERGY RELATION The energy consumed per unit time is given by the equation U = Fx V and The total energy per unit volume is given by where V - Velocity of cutting b - Width of cutting t - Depth of cutting This total energy per unit volume is approximately equal to the sum of the following four energies. (i) Shear energy per unit volume on shear plane (Us). (ii) Friction energy per unit volume on the tool face (Uf). (iii) Surface energy per unit volume due to the formation of a new surface area in cutting (Uα). (iv) Momentum energy per unit volume due to the change in momentum associated with the metal as it crosses the shear plane (Um). Uα and Um are too small when compared to above energies. Hence, it could be neglected.
