What is forming in manufacturing processes?

• A process that involves removing material to shape an object

• A process that applies forces or pressure to deform material into a desired shape

• A process that involves pouring molten metal into a mold

• A process that adds material layer by layer to create an object

What does hot working in forming processes involve?

• Deforming the metal below its recrystallization temperature

• Cooling the metal rapidly after shaping

• Deforming the metal above its recrystallization temperature

• Applying extreme pressure to the metal without heating

What is a characteristic of cold working?

• It makes the metal easier to deform

• It reduces the strength of the material

• It increases the strength of the material through strain hardening

• It requires the metal to be heated above its recrystallization temperature

What is die casting primarily used for?

• Non-ferrous metals like aluminum and zinc

• Ferrous metals with high melting temperatures

• Wood and composite materials

• Plastics and polymers

Which process is known for producing parts with complex geometry and tight tolerances?

• Compression molding

• Investment casting

• Extrusion

• Sand casting

What is the most commonly used manufacturing method for plastics?

• Compression molding

• Blow molding

• Injection molding

• Additive manufacturing

Which of the following is a characteristic of injection molding?

• It can be fully automated

• It has very low start-up costs

• It is a slow process

• It is mostly used for thermosets

What is machining in the context of manufacturing processes?

• A process that adds material to build up an object

• A material removal process

• A material deformation process

• A process that combines multiple components into a larger assembly

What distinguishes welding from soldering and brazing?

• Welding uses lower temperatures than soldering and brazing

• The base metal melts during welding

• Welding is only used for plastics

• The base metal does not melt during welding

What is a primary shaping process?

• Casting

• Additive Manufacturing

• Joining

• Machining
