Class Vocabulary

Term	Definition
code	To create programmable sets of instructions for a CNC machine.
computer numerical control	A type of programmable automation, directed by mathematical data, which uses microcomputers to carry out various machining operations.
downtime	Unproductive blocks of time during which operations cease to function, normally due to mechanical problems or a lack of materials.
drill	A machining tool used to penetrate the surface of a workpiece and make a round hole.
electrical circuitry	A closed path that an electric current follows, usually through devices and wires.
end mill	A thin, tall mill cutter with cutting edges that wind up the sides. Both the bottom and side of the end mill are used during milling operations. End mills resemble drills.
face mill	A flat mill cutter with multiple cutting teeth surrounding the tool. The bottom of the face mill is primarily used during milling operations.
finishing	Final operations performed for obtaining desired tolerance and/or surface finish.
fixed automation	A process using mechanized machinery to perform fixed and repetitive operations in order to produce a high volume of similar parts.
grinder	A machine that uses an abrasive to wear away at the surface of a workpiece.
hardware	The physical components of a CNC machine.
interface	The control panel and displays with which the operator interacts with the machine.
job changeover	The time it takes to switch from one part to another.
lathe	A tool commonly used to machine cylindrical forms. It is generally considered the backbone of the machine shop.
machine control unit	A small, powerful computer that controls and operates a CNC machine.
magazine	A arrangement of multiple tools that allows a CNC machine to rapidly change from one machining operation to the next.
mill	A machining tool used to either horizontally or vertically remove metal from the surface of a workpiece.
mylar tape	A thin, yet strong polyester film that was used to transmit programs to numerically controlled machines.
paper tape	A way of transmitting programs to numerically controlled machines. This method is all but extinct.
part program	A series of numerical instructions used by a CNC machine to perform the necessary sequence of operations to machine a specific workpiece.
prototype	The original test model of a product.
punch presses	A machine that uses force to either cut or form a workpiece.
punching	Using force to cut or form a workpiece.
repeatable	The ability to position workpieces in the same place part after part.
stamping	Forming metal with the use of dies and punches.
three-axis curvature data	Information that describes the motion and position of an object using three-dimensional data.
turret press	A CNC punch press that contains several tools.
welder	A device used to join two pieces of metal together through the application of heat.
