CIM 2.2 Flashcards
Rapid prototyping process that builds a part by ejecting adhesive bonding material onto successive layers of powders. Note that this term is often used to describe all rapid prototyping processes.
3D Printing
Acrylonitrile Butadiene Styrene. A thermoplastic with rubber added for high toughness.
ABS
Fabrication of a part by adding material.
Additive Process
The process of putting a product together out of separate parts.
Assembling
Length of time for the physical construction of a rapid prototype, excluding preparation and post-processing time. Also known as run time.
Build Time
The process in which a solid material is made into a liquid, poured into a mold, and allowed to harden in the shape of the mold.
Casting
Any of various hard, brittle, heat-resistant, and corrosion-resistant materials made by shaping and then firing a nonmetallic mineral, such as clay, at a high temperature.
Ceramics
Physical model intended primarily for design review and not meant to be sufficiently accurate or durable for full functional or physical testing.
Concept Model
Process in which the properties of a material are changed using mechanical, thermal, or chemical means.
Conditioning Process
Similar to permanent mold casting except that the metal is injected into the mold under high pressure.
Die Casting
A process by which an electrode spark is used to erode small amounts of material from a work piece.
Electrical Discharge Machining (EDM)
A process in which a stream of electrolyte (typically salt water) is pumped at high pressure through a gap between the positively charged work and the negatively charged tool (electrode).
Electrochemical Machining (ECM)
Resources of which there are a limited supply.
Exhaustible Resources
Machining a surface to size with a fine feed produced in a lathe, milling machine, or grinder.
Finishing Process
A process by which metal is heated and shaped by plastic deformation by suitably applying compressive force.
Forging
A process that changes the size and shape of a material by a combination of force and a shaped form.
Forming Process
Fused Deposition Modeling. Rapid prototyping process in which a filament of wax or polymer is extruded onto the existing part surface from a workhead to complete each new layer.
FDM
An operation that removes material by rotating an abrasive wheel or belt against the work.
Grinding
Material that has been changed from raw material so that it is ready to be used in manufacturing. Also referred to as standard stock.
Industrial Material
A process during which plastic is heated in a machine and forced into a cavity by a screw or ram. The material solidifies and is then ejected.
Injection Molding
Laminated Object Manufacturing. Rapid prototyping process in which sheet stock is cut and bonded into a stack.
LOM
Any of a category of electropositive elements that usually have a shiny surface, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires.
Metals
A manufacturing process in which the industrial material is made into a liquid. The liquid is then introduced (poured or forced) into a prepared mold of proper design.
Molding
Materials that undergo a permanent change in shape or size when subjected to a particular amount of stress.
Plastics
