Question

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

• A. Brittle material
• B. Ductile material
• C. Hard material
• D. All of the above

Hint:

To produce continuous chips, focus on machining ductile materials, which are easier to deform. For brittle or hard materials, adjust cutting parameters to minimize chip breakage.

Answer 1

The Correct Option is B

In metal cutting operations, continuous chips are typically produced when machining ductile materials. Ductile materials, such as aluminum or mild steel, tend to form long, continuous chips because they deform easily under cutting forces, allowing for smooth material removal. In contrast, brittle materials tend to break into smaller, fragmented chips during cutting due to their low plasticity. Hard materials can also produce fragmented chips but are generally more difficult to machine.
