Material Processing Material processing changing the shape size

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
