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

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

It is Due the presence of carbon.

Segmental means discontinuous, breked chips are formed during machining, cast iron is brittle material so it formed segmental chips.

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.

Brittle material is stronger in compression and weak in tension.

Segmental chips is known as discontinuous chips. Therefore discontinuous chips are formed during the machining of brittle materials like cast iron.

Anyone give details of high carbon steel.

KUMAR LK said:   6 years ago
It can resist compressive loads, the chips are discontinuous or segmented because it is mixed graphite. So the chips are discontinuous.
