Question:-
Option (A)
Brittle material
Option (B)
Ductile material
Option (C)
Hard material
Option (D)
Soft material
Correct Option:
A
Question Solution:
The chips that are fomed during metal cutting operations can be classified into 3 types:
1. Discontinuous or segmental chips - formed while cutting brittle material like cast iron
2. Continuous chips - formed while cutting ductile material like mild steel
3. Continuous chips with built-up edge - observed in aluminium & stainless steels
