Mechanics of Metal Cutting - Manufacturing Technology
Let V - Cutting speed (m/s) Fz = Cutting force, N Work done in cutting, W = Fz × V N-m/s or W Work done in shear, Ws = Fs × Vs
WORK DONE AND POWER REQUIRED IN CUTTING Let V - Cutting speed (m/s) Fz = Cutting force, N Work done in cutting, W = Fz × V N-m/s or W Work done in shear, Ws = Fs × Vs where Vs = Velocity of chip relative to work in m/s. Fs = Shear force in N Work done in friction, Wf = P × Vc where Vc - Velocity of chip relative to the cutting tool in m/s P - Frictional force Total work done, W = Ws + Wƒ Horse power used in metal cutting is estimated by measuring the gross horse power (HP)g and tare horse power (HP)t.
