Flashcards in Chapter 1 Deck (17):
Name the materials in Manufacturing. 3 categories.
Metals, Ceramics, and Polymers
Transforms a work piece from one state of completion to an advanced state
Assembly Operation. Name types.
Joins two or more components together.
Joining - welding, brazing, soldering. Mechanical assembly - rivets, threaded fasteners
Shaping Operation. Name types.
Alter the geometry.
Solidification, particulate, deformation, and material removal.
Property enhancing operations. Name types.
Improve the physical properties of a material without changing the shape.
Heat treatments like annealing and sintering
Surface processing operations. Name types.
Clean, treat, coat or deposit material into the surface.
Cleaning, surface treatments, coating and thin-film deposition.
heating liquid that cools and solidifies
powder is formed for geometry and heated to strengthen.
Ductile solid deformed to shape the part
Material Removal Process
Brittle or solid material has material removed to a desired geometry.
How many units comprise low, medium and high production.
1 - 100
10000 - 1 million
High customization, high variety products.
general purpose equipment. Low volume production.
Low investment but high variable cost
Low customization, low variety products
Specialized machines. Mass production.
High investment but low variable cost.
Steel vs Cast iron
Steel - 0.02% to 2.11%
C.I. - 2% to 4%.
Si - 0.5% to 3%
clay, silica (glass), alumina and silicon carbide (grinding)
Name 3 Polymers and describe.
thermoplastic polymers - nylon. multiple heating and cooling cycles without substantially altering molecular structure.
Thermosetting polymers - Cure into rigid structure on cooling from heated plastic condition.
elastomers - elastic polymers. Rubber.
