Which of the following is NOT the smith forging operation?

Explanation:

Smith Forging:

The process involves heating the stock in the blacksmith’s hearth and then beating it over the anvil. To get the desired shape, the operator has to manipulate the component in between the blows. The types of operations available are fullering, flattening, bending, upsetting, and swaging.

Applications of Smith Forging

• It is used to fabricate components like bolts, nuts, keys, tongs, springs, etc.
• The agricultural tool and links are fabricated by the smithy forging mechanisms.

Upsetting

• Upsetting is the process of increasing the thickness of a bar with the corresponding reduction in length by applying the end pressure.
• The pressure is applied at the end of the bar against the angle clamped in position and then hammering against it.

Bending

• Bending is a very common forging operation.
• It is done at the edge of the anvil face, over the anvil born, or by inserting the end in the hole and bending the bar with a hong.

Setting down

• It is the process of local thinking down of the workpiece by hammering.

Casting

It is a process of manufacturing metallic components. The process involved the following basic steps:

• Melting the metal.
• Pouring it into a previously made mould or cavity which conforms to the shape of the desired component.
• Allowing the molten metal to cool and solidify in the mould.
• Removing the solidify component from the mould, cleaning it and subjecting it to further treatment, if necessary.​
