Flashcards in Chapter 1 Deck (17):
1

Name the materials in Manufacturing. 3 categories.

Metals, Ceramics, and Polymers

2

Processing Operation.

Transforms a work piece from one state of completion to an advanced state

3

Assembly Operation. Name types.

Joins two or more components together.

Joining - welding, brazing, soldering. Mechanical assembly - rivets, threaded fasteners

4

Shaping Operation. Name types.

Alter the geometry.

Solidification, particulate, deformation, and material removal.

5

Property enhancing operations. Name types.

Improve the physical properties of a material without changing the shape.

Heat treatments like annealing and sintering

6

Surface processing operations. Name types.

Clean, treat, coat or deposit material into the surface.

Cleaning, surface treatments, coating and thin-film deposition.

7

Solidification process

heating liquid that cools and solidifies

8

Particulate process

powder is formed for geometry and heated to strengthen.

9

Deformation process

Ductile solid deformed to shape the part

10

Material Removal Process

Brittle or solid material has material removed to a desired geometry.

11

How many units comprise low, medium and high production.

1 - 100
100 -10000
10000 - 1 million

12

Job shop.

High customization, high variety products.

general purpose equipment. Low volume production.

Low investment but high variable cost

13

Flow shop

Low customization, low variety products

Specialized machines. Mass production.

High investment but low variable cost.

14

Steel vs Cast iron

Steel - 0.02% to 2.11%

C.I. - 2% to 4%.
Si - 0.5% to 3%

15

Ceramics

clay, silica (glass), alumina and silicon carbide (grinding)

16

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.

17

Net Shape processes vs Near Net Shape processes

NSP transform nearly all of the starting material into product and require no subsequent machining to achieve final part geometry.

NNSP require machining
