Total questions: 14
Worksheet time: 7mins
What does metal forming involve?
Machining and cutting
Pressing, squeezing, or rolling
Melting and casting
Welding and joining
What property of metals does forming depend on?
Ductility
Malleability
Plasticity
Elasticity
What is the most important of all the metal forming processes?
Cold rolling
Hot rolling
Extrusion
Forging
What does the slabbing mill do to 14-ton ingots?
Reduces them into slabs about eight inches thick
Melts them down
Cuts them into smaller pieces
Shapes them into tubes
What is the effect of hot rolling on metal?
Makes the metal brittle
Makes the metal tougher and more resistant to failure
Makes the metal softer
Decreases the metal's strength
What is the purpose of lubricants in cold rolling?
To reduce friction and carry away some of the heat produced
To cool down the machinery
To increase the metal's hardness
To polish the metal surface
What happens to the metal's grain structure after cold rolling?
It becomes finer and more uniform
It remains unchanged
It disappears and is replaced by a crystalline structure
It becomes lengthened in the direction of rolling
What process is used to restore softness and ductility to metal after cold rolling?
Quenching
Annealing
Tempering
Hardening
What is the purpose of forging?
To make metal sheets
To create intricate shapes or large parts
To refine metal ores
To produce metal powders
How does drop forging affect the metal's grain?
It makes the grain structure irregular
It has no effect on the grain structure
It disrupts the grain structure completely
It causes the grain to follow the shape of the die
What is the result of extrusion in metal forming?
An increase in metal brittleness
A decrease in metal strength
A rough surface needing further processing
A fine surface finish and accurate shape
What is the role of lubrication in the drawing of wire?
To prevent the wire from breaking
To increase wire thickness
To enhance electrical conductivity of the wire
To reduce friction and minimize die wear
What is the effect of annealing on cold-rolled metal?
Restores its regular grain structure
Increases its brittleness
Makes it suitable for welding only
Decreases its strength significantly
What is a key characteristic of metal that enables forming processes?
Its electrical conductivity
Its plasticity
Its color
Its melting point
