GATE ME 1997 | Metal Cutting Question 63 | Production Engineering

GATE ME 1997

MCQ (Single Correct Answer)

-0.6

A cutting tool has a nose radius of $$1.8mm$$. The feed rate for a theoretical surface roughness of $${R_t} = 5$$ microns is

$$0.268$$ $$mm/rev$$

$$0.187$$ $$mm/rev$$

$$0.036$$ $$mm/rev$$

$$0.0187$$ $$mm/rev$$

GATE ME 1989

MCQ (Single Correct Answer)

-0.6

In turning operation the feed rate could be doubled to increase the metal removal rate To keep the same level of surface finish, the nose radius of the tool has to be

Doubled

Halved

Multiplied by $$4$$ time

Kept unchanged.

GATE ME 1988

MCQ (Single Correct Answer)

-0.6

Pure metal pose machinability problem in turning operations. The reason is the

Increased length of contact due to the production of continuous chip

Susceptibility to chemical reactions

Tendency to form intense adhesion joint with the tool face

Absence of inclusions which aids chip formation
