Quiz 1: Part 1 Flashcards
What is manufacturing?
the process of converting raw material into products.
How and what are the processes of manufacturing?
by design; physical and chemical treatment
How do the processes work?
Altering geometry, properties and appearance
Discrete Products
individual parts/pieces; ex: paper plates, cans, nails, gears
Continuous Products
cut into individual pieces; ex: sheet metal, tubing, pipe, money
Why is manufacturing important?
it is key for national and global economics
Manufacturing is?
an add-value process as it is associated with the nations GDP
Nations with the largest GDP
focus on high value added products; ex: electronics, medical devices, automobiles, airplanes, machinery
Primary Industries
exploit natural resources; ex: oil, metal
Secondary Industries
take outputs of primary industries and convert them into consumer goods; ex: phones, books, makeup, automobiles
Tertiary Industries
service sector, sending/giving of consumer goods; ex: hotel, banking, education
Low Production
1 - 100 units per year; high variety
Medium Production
100 - 10,000 units per year
High Production
10,000 - millions per year; low variety
Processing Operations
- Shaping
- Property enhancing
- Surface processing
Assembly Operations
- Permanent joining
- Mechanical fastening
Shaping Process
metal casting, molding
Surface Process
chemical and mechanical processes to remove contaminants
Mechanical Processes
shot peening, sand blasting
Physical (Chemical) Processes
diffusion, ion implantation
Manufacturing Engineering
planning the entire process
Production Planning & Control
solving the logistics problems; ex” ordering, scheduling, checking of progress
Quality Control
making sure the production is of high quality
Globalization
use of outside contracts to perform work
Offshore Outsourcing
using overseas locations to perform work then transport to US
Sustainable Product
minimal negative impact on environment and society throughout its life-cycle
Near-Shore Outsourcing
use of neighbors “canada, mexico” to perform work and transport via truck
Sustainable: Materials
renewable, recycled, bio degradable
Sustainable: Manufacturing
energy-efficient, reduction of emissions and waste
Longevity
durability, long-lasting, can be repaired or refurbished
End of Life-Cycle
easily recycled, composted in an environmentally friendly manner
Metals
- use of alloys
- composed of 2 or more elements (1 being metallic)
Ferrous Metals
based on iron; (steel, cast iron)
Non-ferrous Metals
other metallic elements and their alloy; (gold, Al, Cu, Ni, Silver, tin)
Atoms
composed of positive charged nucleus, surrounded by negative charged electrons
Primary Bonds
ionic, covalent, metallic
Secondary Bonds
hydrogen, van-deer walls
