Chip type for cast iron: typical chip morphology during machining Identify the most common chip type produced when machining gray cast iron under usual conditions. Choose the correct option.

Difficulty: Easy

Continuous chips
Discontinuous (segmental) chips
Continuous chips with built-up edge
None of these

Correct Answer: Discontinuous (segmental) chips

Explanation:

ConceptBrittle materials (e.g., gray cast iron) fracture ahead of the tool leading to discontinuous chips. Ductile metals (e.g., mild steel) tend to form continuous chips.

Final AnswerDiscontinuous (segmental) chips
