Mechanical Engineering > GATE 2022 SET-1 > Metal Cutting
Under orthogonal cutting condition, a turning operation is carried out on a
metallic workpiece at a cutting speed of 4 m/s. The orthogonal rake angle of the
cutting tool is 5º. The uncut chip thickness and width of cut are 0.2 mm and 3 mm,
respectively. In this turning operation, the resulting friction angle and shear angle
are 45º and 25º, respectively. If the dynamic yield shear strength of the workpiece
material under this cutting condition is 1000 MPa, then the cutting force is
______________ N (round off to one decimal place).
Correct : 1333.3
