Materials Processing - ISEE 140

Materials Processing Purpose

To give us the tools and language to understand what’s going on in a machine shop.

Steel Scale

a exact measuring tool that measures from the end of the rectangle in metric or imperial.

Manufacturing

A sequence of operations

Waste

non-value added goods/services (time, transport, labor, etc.)

Materials Processing

value-added process

Consumer Goods

goods that we “consumers” want to buy

Capital Goods

goods needed for service use; may eventually become a consumer good

Metals

a type of element characterized by having a low relative electronegativity making it malleable and/or ductile.

• Properties: Ferrous vs. non-Ferrous; with Iron (Fe) or not with iron. 

• Ex: Ferrous: Steel, Non-Ferrous: Copper, Aluminum, Bronze

Ceramics

a nonmetallic, inorganic solid material, typically made from compounds of metals and nonmetals, held together by ionic and covalent bonds

• Properties: Bio compatible/food safe, super hard, good insulator, brittle

• Ex: clay, silica, alumina, silica carbide

Polymers

a type of material to which humans can construct and create any material property with

• Properties: low melting point, durable, inexpensive

• Ex: thermoplastics, elastomers, AVS PVC, Poly Urethane, thermosets

Composites

two or more materials woven together of different physical/chemical properties

• Properties: High strength/weight ratio, expensive, process intensive

• Ex: Kevlar

Processing Operations

• Molding:

• Forming: shaping (malleable/ductile)

• Material Removal

Permanent Jointing Operations

• Glue/Mortaring

• Welding/Soldering

Mechanical (partial) Fastening

• Replaceable, Modular Design, Easier Construction

• Screws, Bolts/nuts, nails

Manufacturing Support System

1. Manufacturing Engineer

2. Product Planning & Control

3. Quality Control

Vertical Integration

owning multiple segments of the supply chain

Horizontal Integration

owning multiple of the same segment of the supply chain
