Day 12 Outside Work: Forming Process Flashcards
Which factor significantly affects the forming process of sheet metal used in aircraft?
The type of material and its condition
Why are blind fasteners frequently used in aircraft repair and maintenance?
They can be installed when only one side of the structure is accessible
What is the significance of the ‘K-factor’ in bending operations?
It is a value used to calculate the bend allowance
What is a primary requirement when preparing a hole for a Rivnut installation?
Ensuring good hole preparation and burr removal
During sheet metal forming, what does stretching the metal primarily involve?
Expanding the metal by thinning it
How does the temper condition of aluminum affect its ability to be formed?
Softer tempers allow for easier and more extensive forming
What is a critical aspect to monitor during the metal shrinking process?
The distribution of compression
What is the primary risk when using a material that is too hard or improperly tempered for a forming process?
The material may crack or fail during forming
Why are common pull-type pop rivets not approved for use on certificated aircraft structures?
They are not strong enough for structural use
What is the main challenge when shrinking metal during forming operations?
It is more difficult than stretching
What should be considered when selecting a method for forming a part on an aircraft?
The material and the specific shape required
Why is annealing important in the forming of complex metal parts?
It softens the metal, allowing for more extensive shaping
Which process is used to make sharp bends in a piece of sheet metal?
Bumping
What is the main advantage of the Cherry Rivetless Nut Plate over traditional riveted nutplates?
It reduces the number of rivet holes needed
Which statement best describes the purpose of using a forming block in sheet metal work?
To provide support and shape during bending
