In which of the following operations is work pulled through the die opening?

Concept:

• Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing dies.
• Drawing is usually performed at room temperature, thus classified as a cold working process, but it may be performed at elevated temperatures for large wires to reduce forces.

Additional Information

• The bundle is another process where thousands of conventional drawn wires are bundled and drawn simultaneously. Bundle drawing produces wires that are somewhat polygonal, rather than round in cross-section. It is employed to increase productivity by drawing many wires in a single operation.
