QUESTION: 10

Swaging is an operation of

Solution:

In swaging a solid rod or tube is subjected to radial impact forces by a set of reciprocating dies. The die movements can be obtained by means of a set of rollers in a cage, is an action similar to that of a roller bearing.

QUESTION: 11

Which one of the following is an advantage of forging

Solution:
QUESTION: 12

Bolt heads are manufactured by

Solution:
QUESTION: 13

In the forging operation, fullering is done to

Solution:

Fullering is performed by a pair of concave dies and in this material moves away from the centre this decreases the size of a slab.

QUESTION: 14

 Cold shut (lap) may occur in products obtained by:

Solution:
QUESTION: 15

Identify the process in which the metal is shaped by means of intermittent blows on it

Solution:

Swaging is generally used for reducing the diameter, or tapering the end of bars and tube through rotating dies.

QUESTION: 16

Which one of the following processes is adopted for manufacturing of steel balls for ball bearing?

Solution:
QUESTION: 17

Which one of the following metal forming processes in not a high energy forming processes?

Solution:

In metal forming process, energy source such as chemical, magnetic and electrical discharge can be used. Since in ail such processes, the rate of energy flow is of much higher order, these are commonly called high-energy rate (HER) processes. Three common HER processes are:
1. Explosive forming
2. Electrohydraulic forming
3. Electromagnetic forming

QUESTION: 18

A forging method for reducing the diameter of a bar and in the process making it longer is termed as

Solution:
QUESTION: 19

The process of coining is

Solution:

Coining is cold forging operation.

QUESTION: 20

Which of the following manufacturing process will produce strongest component?

Solution:
QUESTION: 21

Which of the following metals is, best suitable for extrusion either hot or cold?

Solution:
QUESTION: 22

Collapsible tooth paste tubes are manufactured by

Solution:
QUESTION: 23

What does hydrostatic pressure in extrusion process improve?

Solution:

Hydrostatic pressure increases the ductility of the material. Therefore, brittle material can be extruded bv this method.

QUESTION: 24

In the metal extrusion process, when the.die angle increases, the required extrusion force

Solution:

As the die angle increases, the contact between the die and workpiece decreases which decreases the force required but when the die angle increases beyond a certain value, this creates hinderance in the flow of metal hence force required increases.

QUESTION: 25

Which metal forming process is used for manufacturing of long steel wire?

Solution:
QUESTION: 26

A floating mandrel is used in

Solution:

Tube drawing is done by
1. Tube sinking operation
2. Tube drawing with fixed mandrel
3. Tube drawing with floating mandrel
4. Tube drawing with moving mandrel
