• # question_answer In orthogonal cutting, the depth of cut is 03 mm at a cutting speed of 2 m/s. If the chip thickness is 0.75 mm, the velocity is: A) 133 m/s            B) 2 m/sC) 23 m/s              D) 3 m/s

Chip velocity, ${{v}_{f}}=$Chip thickness ratio $\times$ Cutting speed $=\frac{0.5}{0.75}\times 2$ $=\text{ }1.33\text{ }m/s$
