MATEPRO (Group Quiz 1 MODULE 1) Flashcards
What is Process?
A Process converts a material from one form to another adding value to it.
Manufactured goods are typically divided into 2 classes:
Producer goods
Consumer goods
The vast majority of objects around
us consist of numerous individual
pieces that are built and assembled
by a combination of processes called
[blank]
manufacturing
- bolts, nuts,
paper clips, etc. - Individual items
DISCRETE PRODUCTS
a roll of
aluminum foil, a spool of wire, metal or
plastic tubing
- cut into individual pieces
CONTINUOUS PRODUCTS
every individual products has a
certain value which starts with raw
materials subjected to a sequence of
processes
VALUE
Production of Steel in Asia
600-800 A.D.
First Industrial Revolution
1780-1850
Second Industrial Revolution
1947
Third Industrial Revolution
1960-Industry 4.0 (modern times)
- involves the creative and systematic prescription of the shape
and characteristics of an artifact to achieve specified objectives while
simultaneously satisfying several constraints. - 80% of the cost of product development and manufacture is
determined by the decisions made in the initial stages of design.
PRODUCT DESIGN
Traditional processes using the sequential methodology may
appear to be straightforward and logical; in practice, however, it is
wasteful of both time and resources.
THE DESIGN PROCESS
also called simultaneously engineering by which all relevant
disciplines (departments and personnel) are already simultaneously
involved even from the earliest stages of product design.
- to bring products to the market as rapidly as possible
CONCURRENT ENGINEERING
- a prototype is a physical
model of an individual component or
product - carefully reviewed for
possible modifications to the original
design, materials of production
method
Prototype Production
is done prior to full
scale/mass production to validate and
document the manufacturing processes
for the developed product
Pilot Production
- prototypes can now be made rapidly
and at low cost using various specialized
technologies and CAD/CAM - available for wide variety of materials
ranging from plastics and ceramics to metallic
materials - examples are: 3D Printing (Additive
manufacturing), laser cutting
RAPID PROTOTYPING
a software-based method that uses
advanced graphics and virtual-reality
environments to allow designers to view and
examine a part in detail
VIRTUAL PROTOTYPING (Simulation-based
design)
Is a major consideration in manufacturing because all
components, regardless of their size, eventually have
to be assembled into the final product
DIMENSIONAL TOLERANCE
In concurrent engineering, the
design and manufacture of
products are integrated with a
view toward optimizing all
elements involved in the [blank] of the product.
Life Cycle
Stages of life cycle:
- Product start-up
- Rapid growth of the
product in the marketplace - Product maturity
- Decline
[blank] is comprehensive approach to integrating the design process with
production methods, materials, process planning, assembly, testing, and quality
assurance
DESIGN FOR MANUFACTURE (DFM)
Experience has indicated that a product which is easy to assemble is usually
also easy to disassemble
- Assembly costs in manufacturing operations can be substantial, typically
ranging from 20 to 60% of the total product cost.
DESIGN FOR ASSEMBLY (DFA) and DISASSEMBLY (DSD)
- The design should take into account the concept that, for ease of access,
components that are most likely to be in need of servicing be placed, as much as
possible, at the outer layers of the product.
DESIGN FOR SERVICE (DFS)
“mistake proofing” or “inadvertent error
prevention”
*Is the use of any automatic device or method that
either makes it impossible for an error particularly
human error to occur
