It is a form when machining of brittle material like cast iron, brass etc. With slow cutting speed. Chips cut into small segment during cutting. This is formed during slow cutting speed with a small rack angle.

Cast iron is not a brittle material, it is a harder material.

Continuous chips form during machining ductile material. Cast iron contain large % of carbon than steels hence it is harder than steel.

From Fe3C diagram we know that in all types of steels the carbon is up to 2% and from 2% to 6. 6% carbon content is found in cast iron. So if the carbon % is more then the brittleness of the substance will be more and the more brittle material will have more tendency to generate segmental chips during machining.

Cast iron is a brittle and hard material. So very small parts or segmental form of chips are crated during machining of cast iron.

Nice answer. Thank you all.

Brittle material machining chip is called segmental chip. So cast iron brittle material.

Maggiee said:   9 years ago
For Brittle material segmented chips are formed during machining.

Eg. Cast iron.

Segmented chips are nothing but discontinuous chips which are formed by the brittle material during machining, among the options the most favoured option is cast iron which is brittle material.

Due to highest amount of carbon content the structure becomes brittle so cast iron gives discontinuous or segment chips.
