GATE ME 2014 Set 3

MCQ (Single Correct Answer)

-0.3

Cutting tool is much harder than the work piece. Yet the tool wears out during the tool-work interaction, because

Extra hardness is imparted to the work piece due to coolant used

Oxide layers on the work piece surface impart extra hardness to it

Extra hardness is imparted to the work piece due to severe rate of strain

Vibration is induced in the machine tool

MCQ (Single Correct Answer)

-0.3

Friction at the tool - chip interface can be reduced by

Decreasing the rake angle

Increasing the depth of cut

Decreasing the cutting speed

Increasing the cutting speed
