Transcript Material Processing

Material Processing
• Material processing changing the shape,
size and/or
characteristics
Forming
Changing the
shape of a
material
Casting
• Casting - pouring a
material into a mold
that has a particular
shape. i.e. candles;
Extruding
• pulling or pushing a
material through a die.
i.e. toothpaste coming
out of a tube, pipe,
tubing, storm window
frames, wire
Forging
• hammering a piece
of material into a
specific shape
Separating
• Separating removing parts
of material to a
specific size. i.e.
filing, drilling a
hole in wood,
sanding
Shearing
• Shearing - separating
by use of a wedge
(cutting). i.e. cutting
paper with scissors,
cutting sheet metal
Machining
– Machining - taking
off small pieces of
material. i.e. milling,
engraving,
sharpening with a
grinder.
Sawing
• Sawing - using a
blade to cut
material. Usually
produces small
chips as a waste
product.
Combining
• Combining - joining
materials together. i.e.
painting, gluing, nailing,
bonding.
Conditioning
• Conditioning –
changing the
internal structure of
a material
Material processes
• Thermal processes - using
heat to change materials.
– i.e. baking, boiling,
freezing, steel, glass,
petroleum
Mechanical
• Mechanical processes
- using force to
change materials.
– i.e. hammering,
penning, machining,
shearing
Magnetic Processes
• Magnetic processes using magnetic forces to
change materials.
–i.e. making cassette
tapes, magnetizing a tool
(screwdriver)
Acoustical Processes
• Acoustical processes
:using sound wave to
change or test
materials.
– i.e. ultrasound,
medicine
Optical Processes
• Optical processes using light to change
materials.
– i.e. photoelectric
processes, laser, fiber
optics
Electrical Processes
• Electrical processes
- using electrons to
change materials.
– i.e. electrical
discharge
machining,
electromagnetic
waves
