This set of Manufacturing Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Tool Geometery and Nomenclature-1”.

1. 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. 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. 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.

4. 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. 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. 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. 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. 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. 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. 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
