Chip Formation & Chip Breaker
The type of chip produced depends on the material being machined and the cutting conditions at the
time. These conditions include the type of tool used tool, rate of cutting condition of the machine and the
use or absence of a cutting fluid
.
Continuous Chip
This leaves the tool as a long ribbon and is common when cutting most ductile materials such as mild
steel, copper and Aluminium. It is associated with good tool angles, correct speeds and feeds, and the
use of cutting fluid.

Discontinuous Chip
The chip leaves the tool as small segments of metal resulted from cutting brittle metals such as cast iron
and cast brass with tools having small rake angles. There is nothing wrong with this type of chip in these
circumstances.
