# MCQs on Tool Geometery and Nomenclature-1

1 - Question

Angle between the rake face and plane perpendicular to rake face is known as:
a) Side rake angle
b) Side relief angle
c) End relief angle
d) Back rake angle
Explanation: Side rake angle is the angle between the rake face and plane perpendicular to rake face.

2 - Question

Angle between the rake face flank of tool and perpendicular line drawn from cutting point to base of tool is known as:
a) Side rake angle
b) Side relief angle
c) End relief angle
d) Back rake angle
Explanation: Side relief angle is the angle between the flank of tool and perpendicular line drawn from cutting point to base of tool.

3 - Question

Angle between side cutting edge and axis of tool is known as:
a) Side rake angle
b) Side relief angle
c) Side cutting edge angle
d) Back rake angle
Explanation: Side cutting angle is the angle between side cutting edge and axis of tool. advertisement

4 - Question

Angle between end cutting edge and axis of tool is known as:
a) Side rake angle
b) Side relief angle
c) End cutting edge angle
d) Back rake angle
Explanation: End cutting angle is the angle between end cutting edge and axis of tool.

5 - Question

Angle between side cutting edge and end cutting edge in the top surface plane of tool.
a) Side rake angle
b) Side relief angle
c) Side cutting edge angle
d) Nose angle
Explanation: Nose angle is the angle between side cutting edge and end cutting edge.

6 - Question

With an increase in lip angle keeping side rake angle constant, strength of tool.
a) Increases
b) Decreases
c) Remains constant
d) None of the mentioned
Explanation: Thickness of tool tip increase with an increase in lip angle, hence the strength of tool increase.

7 - Question

For large positive back rake angle, tool will be
a) Weaker
b) Stronger
c) Smoother
d) Harder
Explanation: With the increase in positive back rake angle, lip angle decreases and tool tip become thin.

8 - Question

For large negative back rake angle, tool will be
a) Weaker
b) Stronger
c) Smoother
d) Harder
Explanation: With an increase in negative back rake angle, lip angle increases and tool tip become thick and hence the strength of tool will increase.

9 - Question

Which of the following will give better chip flow?
a) Positive back rake angle tool
b) Negative back rake angle tool
c) Zero back rake angle tool
d) None of the mentioned
Explanation: With positive back rake angle, lip angle decreases and space for chip flow increases and hence it will give better chip flow.

10 - Question

Which of the following will give large friction during chip flow?
a) Positive back rake angle tool
b) Negative back rake angle tool
c) Zero back rake angle tool
d) Small lip angle tool
