1. Production of thin sheets of a flexible tape by casting in the particulate forming process may be termed as _________________
a) slip casting
b) hydroplastic forming
c) powder casting
d) tape casting
Explanation: Tape casting is a very old process and is used in the formation of flexible tapes
2. Which one of the following can act as a modifier in glass forming process?
a) Silicon dioxide
b) Sodium oxide
c) Magnesium oxide
d) Phosphorous oxide
Explanation: Magnesium oxide is used as a viscosity modifier, thus making glass melt viscosity to be in the desired range for proper formation of the filaments.
3. The word ceramic stands for which of the following meaning?
a) Soft
b) Burnt
c) Hard
d) Tough
Explanation: Ceramics convey the meaning of burnt materials. This is so because in olden days, making pottery and bricks involves burning wood, coal and gas.
4. Which one of the following ceramics can be used as a pigment in paints?
a) Silicon carbide
b) Silicon oxide
c) Aluminum oxide
d) Titanium oxide
Explanation: Titanium white (titanium oxide) used as a pigment in pains. It is used so, because of its SFC (self-cleaning capacity) nature.
5. 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
6. 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.
7. Angle between side cutting edge and axis of tool is known as:
a) Side rake angle
b) Side relief angle
c) Side cutting angle
d) Back rake angle
Explanation: Side cutting angle is the angle between side cutting edge and axis of tool.
8. Angle between end cutting edge and axis of tool is known as:
a) Side rake angle
b) Side relief angle
c) End cutting angle
d) Back rake angle
Explanation: End cutting angle is the angle between end cutting edge and axis of tool.
9. 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) End relief angle
d) Nose angle
Explanation: Nose angle is the angle between side cutting edge and end cutting edge.
10. 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.
