MCHE 365 MANUFACTURING PROCESS
TEST 1(100% CORRECT.)
Prototyping - ANSWERSan original working model of the product. Can include
modifications to original design, material selection, production methods
Computer Simulation - ANSWERSeffective tool in complex production systems.
Evaluates performance of product and planning the manufacturing system to produce it
Rapid Prototyping - ANSWERSRelies on CAD/CAM and various manufacturing
techniques. Can significantly reduce development time and costs. 3D printing is a
common method
Virtual Prototyping - ANSWERSSoftware form of prototyping. Uses advanced graphics
and virtual-reality environments
DFMA - ANSWERSrequires that the designers acquire a fundamental understanding of
the characteristics, capabilities, and limitations of materials, production methods,
machinery, and equipment.
DFMA principles - ANSWERSMinimize part count, standardize parts and materials,
create modular assemblies, parts are multi-functional, efficient joining, reduce
manufacturing operations
Product Life Cycle - ANSWERSProduct development, market introduction, growth,
maturation, decline
Just in time production (JIT) - ANSWERSa process that redefines and simplifies
manufacturing by reducing inventory levels and delivering raw materials at the precise
time they are needed on the production line
Kanban - ANSWERSA tool for JIT. Signals when inventory. process is getting low
Lean Production - ANSWERSaims at continuously improving the efficiency and
profitability of a company by removing all types of waste from its operations and dealing
with problems as soon as they arrive
Six SIGMA - ANSWERSa rigorous statistical analysis process that reduces defects in
manufacturing and service-related processes
5 phases of Six SIGMA - ANSWERSDesign, measure, analyze, improve, and control
Kaizen - ANSWERSJapanese term for continuous improvement.
, Strain - ANSWERSthe degree of deformation to which a material is subjected
Modulus of Elasticity (Young's Modulus) - ANSWERSThe relationship between stress
and strain. Measure of stiffness of an object, defined as the amount of strain resulting
from applying a given stress.
Modulus of Resilience - ANSWERSIs a measure of the capacity of the material to
absorb energy without danger of being permanently deformed.
Offset method - ANSWERSmethod for defining yield strength when a proportional limit
is not defined
Ultimate Tensile Strength - ANSWERSsimple and practical measure of the overall
strength of a material
ductility - ANSWERShow large a strain a material withstands before fracture
True stress - ANSWERSRation of force to area
True Strain - ANSWERSRate of increase in gage length
=ln(l/lo)
toughness - ANSWERSarea under the stress strain curve
perfectly elastic - ANSWERSLinear behavior with slip, E
Rigid, Perfectly Plastic - ANSWERSHas an infinite value of E (graph is a horizontal
line).
When load is released, the material has undergone permanent deformation, no elastic
recovery
Rigid, Linearly Strain-Hardening - ANSWERSRequires increasing stress level to
undergo further strain
Elastic, Linearly Strain-Hardening - ANSWERSacceptable approximation of the
behavior of most engineering materials
Strain Hardening - ANSWERSIncrease in shear stress, overall strength, hardness, yield
strength, and tensile strength. (Dislocation driven)
Brittle material - ANSWERSmaterials that exhibit little or no yielding before failure
