GATE ME 1989 | Metal Cutting Question 93 | Production Engineering

GATE ME 1989

MCQ (Single Correct Answer)

-0.3

Crater wear always starts at some distance from the tool tip because at that point

cutting fluid does not penetrate

chip tool interface temp is maximum

normal stress on rake face is maximum

tool strength is minimu8m

GATE ME 1988

MCQ (Single Correct Answer)

-0.3

The ideal cutting fluid for low speed machining of metals should be one which

removes the heat faster from the cutting zone,

forms a coating on the cutting tool by chemical reaction

forms a low shear strength film of work material at the tool chip interface

serves as a dielectric minimizing thereby reactions due to $$EMF$$ at the interface

GATE ME 1987

MCQ (Single Correct Answer)

-0.3

If in a turning operation both the feed rate and the nose radius are doubled the surface finish values will be

Decreases by $$50\% $$

Increases by $$300\% $$

Increases by $$100\% $$

Remain unaffected

GATE ME 1987

MCQ (Single Correct Answer)

-0.3

Cutting tools are provided with large positive rake angle mainly for

Increasing the strength of the cutting edge

Avoiding rubbing action with the finished surfaces

Reducing the magnitude of the cutting force

Better heat dissipation
