GATE Mechanical 2014 Set 3 | Question: 23
Cutting tool is much harder than the workpiece. Yet the tool wears out during the tool-work interaction, because extra hardness is imparted to the workpiece due to coolant used oxide layers on the workpiece surface impart extra hardness to it extra hardness is imparted to the workpiece due to severe rate of strain vibration is induced in the machine tool
