Why is bending or shaping often required for aircraft skins?

• They are often too thick.

• They have a non-flat nature.

• They are typically made of rubber.

• It's easier to store them.

What powers can be used for tools designed for forming and bending?

• Only manually powered

• Electrically, pneumatically, hydraulically, and manually

• Solar-powered and wind-powered

• Only electrically powered

What is the preferred method for bending sheet metal?

• Press brake

• Cornice brake

• Folding machines

• Compound curve machines

Where are press brakes primarily used?

• Only in aircraft production

• In commercial and aircraft repetitive production

• In small-scale production

• Only in commercial production

What does a press brake consist of?

• A single male die and an adjustable bed

• A fixed female die and a male die powered by a flywheel

• A simple hydraulic lever and a female die

• Only a flywheel and an adjustable bed

Who typically sets up the press brake machine in production?

• Robots

• Unskilled workers

• Semi-skilled workers

• Skilled workers

What is a significant capability of cornice brakes?

• Only bending small sheets of metal

• Only working with very thin metal sheets

• Bending large sheets of metal of various thicknesses

• Duplicating bends many times

In a cornice brake, what component is adjustable for different material thicknesses?

• The sharp nose bar

• The bed

• The clamping nose bar

• The bending leaf

How does adjusting the height of the bending leaf in a cornice brake affect the metal?

• Changes the type of metal that can be bent

• Alters the smoothness of the bend

• Affects the bending angle

• Increases the bending speed

What is the purpose of bending metal past the desired angle in a cornice brake?

• To test the material's flexibility

• To ensure it fits into the machine properly

• To account for spring-back

• To strengthen the material
