Chip formation: materials producing segmental (discontinuous) chips Segmental or discontinuous chips are most commonly formed during machining of which material? Choose the correct option.

Difficulty: Easy

Mild steel
Cast iron
High speed steel
High carbon steel

Correct Answer: Cast iron

Explanation:

Concept/ApproachSegmental (discontinuous) chips occur with brittle materials that fracture ahead of the tool rather than plastically flow.

ExamplesCast iron and some bronzes tend to produce discontinuous chips. Mild steel generally produces continuous or built-up edge chips.

Final AnswerCast iron
