The high cutting speed and large rake angle of the tool will result in the formation of

A continuous chips
B discontinuous chips
C continuous chips with built up edge
D none of the mentioned

Correct Answer: continuous chips

The low cutting speed and small rake angle of the tool are responsible for the formation of discontinuous chips while high cutting speed and large rake angle of the tool will result in the formation of continuous chips.
