Question

In metal cutting operations, discontinuous chips are produced while machining:

• A. Brittle material
• B. Ductile material
• C. Hard material
• D. Soft material

Hint:

In metal cutting, brittle materials often produce discontinuous chips due to their tendency to fracture during machining.

Answer 1

The Correct Option is A

In metal cutting operations, the type of chips produced depends on the material being machined. Discontinuous chips are typically produced when machining brittle materials. This is because brittle materials tend to fracture or break into small pieces during the cutting process, leading to the production of discontinuous or segmented chips.
- Ductile materials tend to form continuous chips because they deform plastically during the cutting process, instead of fracturing.
- Hard materials can produce either continuous or discontinuous chips depending on the specific cutting conditions, but brittle materials are more likely to produce discontinuous chips.
- Soft materials are more likely to produce continuous chips, especially under optimal cutting conditions.
Thus, the correct answer is (1), Brittle material.
