MATERIAL COVERED FOR AND UP UNTIL OUR
FIRST EXAM FOR THE SPRING SEMESTER OF

What is Manufacturing? Answer - The word "Manufacturing" comes from the
latin phrase "Manu Factus" which means "Made by hand." Today,
manufacturing is making products from raw materials by means of various
processes, machinery, and operations.
A country's level of manufacturing activity is directly related to the country's
what? Answer - It is directly related to the country's economic wealth.
Manufacturing adds value to what 2 things? Answer - Adds value to material
or product.
What are the 4 different typesof products? Answer - 1. Discrete Products
2. Continuous Products
3. Products used to make other products.
4. End Products.
,What are some examples of Dicrete Products? Answer - Individual Parts such
as nails and gears.
What are some examples of Continuous Products Answer - A spool of wire,
sheets of metal or plastic.
What are some examples of Products used to make other Products? Answer -
Things such as large presses and sowing machines.
What are some examples of End Products? Answer - Things such as a car, a
tooth brush, and a big boi chair.
Traditionally, Design and Manufacturing were carried out in what way? Answer
- Sequentially
Nowadays, Product Design determines what percentage of the product
development costs? Answer - 70-80%
What is Concurrent Engineering (Simultaneous Engineering) and why was it
introduced? Answer - Concurrent Engineering was introduced because
nowadays, products need to get brought to market Quickly. This is where; all
relevant disciplines are involved within early designs and engineering stages, an
increase in communication between and within disciplines, and it tries to
optimize elements involved with life cycle.
What does Life Cycle Engineering consider? Answer - Design, Production,
Distribution, Use, Disposal, and Recycling
What are CAD systems capable of that is convenient and helpful for engineers?
Answer - They are capable of rapid and thorough analyses of designs.
,What is CAM and what does it involve? Answer - Computer-Aided
Manufacturing and it involves all phases of the manufacturing process, by
utlizing and processing the large amounts of information on materials and
processes.
What are the uses for Computer-Aided Manufacturing? Answer - 1.
Programming for numerical-control machines and for robots for material-
handling and assembly operations.
2. Designing tools, dies, molds, fixtures, and work-holding devices.
3. Maintaining quality control throughout the total operation.
What are some cons to Over Designing a product? Answer - 1. Results in too
costly products.
2. Bulky Parts
3. Materials are too high in quality
4. Precision is higher than needed
What are some aspects of the Optimization process? Answer - Iterative design
process to improve the objective (improve performance, reduce cost, maximize
ROI).
Constraints may include a minimum life, a maximum cost, and/or a maximum
stress level.
What is DFM? Answer - Design for Manufacturing
Why should Design and Manufacturing be interrelated? Answer - To reduce
manufacturing costs
, What is DFA? Answer - Design for Assembly
How should components be arranged for Design for Assembly? Answer - 1.
Easy to grab
2. Easy to assemble
3. Easy to fit proper components with each other to hinder misfit
4. Fasteners, adhesives, welding, soldering, brazing
What is the basic meaning of Design for Disassembly? Answer - The
components should be able to be removed.
Examples of Ferrous Metals Answer - Carbon alloys, Stainless, and tool-and-die
steels
Examples of Nonferrous Metals Answer - Aluminum, low-melting alloys,
precious metals
Examples of Plastics Answer - Thermoplasts and thermosets
Examples of Ceramics Answer - Glass, graphite, diamond, and diamond-like
materials
Examples of Composite Materials (Engineering Materials) Answer - Reinforced
plastics, metal-matrix and ceramic-matrix composites
Examples of New Materials Answer - Nanomaterials, shape memory alloys,
amorphous alloys, superconductor
