Topic: Machining and Machine Tool Operations
The velocity of tool along the tool face is known as
- A. Shear velocity
- B. Chip velocity
- C. Cutting velocity
- D. Mean velocity
Answer: B. Chip velocity
Explanation: In metal cutting, the velocity of the chip ($V_c$) relative to the tool is called the 'chip velocity', which essentially describes the velocity of the tool along the tool face.
