Solution:

In drop forging, what is dropped to forge the work piece?

the work piece at high velocity

the hammer at high velocity

the die with hammer at high velocity

a weight on hammer to produce the requisite impact

Solution:

Why is the metal extrusion process generally used?

For producing uniform solid sections

For producing hollow sections

For producing uniform solid and hollow sections

For producing varying solid and hollow sections

Solution:

Which of the following statements defines the perforating operation?

Punching the edge of the sheet and forming the shape of punch along the edge

Punching a close arrangement of a large number of holes in a single operation

Punching a series of small overlapping slits or holes along a path to cut out a larger contoured shape

None of the above

Solution:

In coining, which is a cold working process, lubricants are not used because

the pressure very low in the process

lubricant may get entrapped in the die cavities and prevent the full reproduction of fine details of the die.

lubricant may get explode in the die cavities due to high pressure in the process

lubricant are reactive to the work metal under cold working
