Chapter 1 Flashcards
Name the materials in Manufacturing. 3 categories.
Metals, Ceramics, and Polymers
Processing Operation.
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.
Solidification process
heating liquid that cools and solidifies
Particulate process
powder is formed for geometry and heated to strengthen.
Deformation process
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
100 -10000
10000 - 1 million
Job shop.
High customization, high variety products.
general purpose equipment. Low volume production.
Low investment but high variable cost
Flow shop
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%
Ceramics
