alloy: a mixture of 2 or more metals or a metal and something else.
brittle: easily shattered or broken.
burr: a rough edge or ridge left on metal or other materials by cutting or drilling.
chip: a small thin piece that is cut or broken off; used for the material that is removed in machining operations.
coke: coal that has had most of the gases removed through heating.
dielectric: a material or medium that does not conduct electricity and that can sustain an electric field.
diode: a semiconductor device that converts alternating current to direct current.
draft: the taper given to a pattern or die so that the work can be removed easily.
ductile: can be stretched, drawn, or hammered thin without breaking; not brittle.
electrolytic: capable of conducting an electric current.
ferrous: of, containing, or derived from iron.
flux: a substance used to aid in the extraction of a furnace charge because of its ability to fuse with undesired matter in forming a more liquid slag
HAZ: Heat Affected Zone - a narrow zone of material close to the cut edge that turns hard and brittle due to heat generated by the cutting process.
helical: having the form of a spiral.
kerf: the cut or channel made by a saw or other cutting process.
knurl: a series of small beads or ridges, as along the edge of a coin.
oblique: having a slanting position or direction; inclined.
photoresist: a substance that can be made to form a tough film by a photographic process, used to mask electrical circuits before chemical etching.
precipitate: a substance that is caused to become insoluble by heat or chemical reagent and separate out from a solution.
radial: branching out in all directions from a common center; situated like a radius.
refractory: resistant to heat; hard to melt.
resistor: a device used in an electrical circuit to oppose the flow of an electric current.
shot: enough material for one cycle of a molding or casting machine.
sinter: a bonded mass of metal particles shaped and partially fused by pressure and heating below the melting point; to become or make into a sinter.
slag: the fused refuse or scum formed on the surface of molten metal.
spindle: a shaftlike part that holds the piece to be turned on a lathe or the tool on a mill.
transistor: a solid-state electronic device that controls current flow without use of a vacuum: transistors are similar in function to electron tubes but have the advantages of being compact, long-lived, and low in power requirements.
