Material Processing

• Changing the shape, size and/or characteristics
  so the same raw material can be used for
  different purposes.

6 Material Processes

• Separating
• Forming
• Casting
• Conditioning
• Combining
• Finishing

4
Material processes

• Separating
• Removing parts of material to a specific size.
• i.e. filing, drilling a hole in wood, sanding

5
Material processes

• Shearing
• Separating by use of a wedge (cutting).
• i.e. cutting paper with scissors, cutting sheet
  metal

6
Material processes

• Machining
• Taking off small pieces of material.
• i.e. milling, engraving, sharpening with a
  grinder.

7
Material processes

• Sawing
• Using a blade to cut material.
• Usually produces small chips as a waste product.

8
Material processes

• Forming
• Changing the shape of a material
• i.e. metal stamping, vacuum forming

9
Material processes

• Forging
• Hammering a piece of material into a specific
  shape.
• i.e. Blacksmith products

10
Material processes

• Casting
• Pouring a material into a mold that has a
  particular shape.
• i.e. candles, plastic fishing lures, etc.

11
Material processes

• Extruding
• Pulling or pushing a material through a die.
• i.e. toothpaste coming out of a tube, pipe,
  tubing, storm window frames, wire

12
Material processes

• Conditioning
• Changing the internal structure of a material

13
Material processes

• Combining
• Joining materials together.
• i.e. gluing, nailing, bonding, assembling

14
Material processes

• Finishing
• Anything that is done to decorate or protect the
  final product.
• i.e. painting, polyurethane, leather oil, shrink
  wrap

15
Material processes

• Mechanical processes - using force to change
  materials.
• i.e. hammering, penning, machining, shearing

16
Material processes

• Magnetic processes - using magnetic forces to
  change materials.
• i.e. making cassette tapes, magnetizing a tool
  (screwdriver)

17
Material processes

• Acoustical processes - using sound waves to
  change or test materials.
• i.e. ultrasound, medicine

18
Material processes

• Optical processes - using light to change
  materials.
• i.e. photoelectric processes, laser, fiber optics

19
Material processes

• Electrical processes - using electrons to change
  materials.
• i.e. electrical discharge machining,
  electromagnetic waves, electrolysis

20
Material processes

• Thermal Processes - using heat energy to change
  materials.
• Cryogenics
• Super-freezing objects in liquid nitrogen.
• Heat-Treating
• Blacksmiths have used this process for centuries.
