Terms that are used on the Manufacturing Automation website
a wiring board, usually constructed as a printed circuit, used to
provide the required connections between logic, memory and I/O modules.
range (usually Hertz) over which a system operates.
an automatic identification technology that encodes data in a printed
pattern of varying-width bars and spaces, in accordance with
Base speed is the manufacturer’s nameplate rating where the motor will
develop rated power at rated load and voltage. With dc drives, it is
commonly the point where full armature voltage is applied with
full-rated field excitation. With ac systems, it is commonly the point
where 60Hz is applied to the induction motor.
Beginner’s All-Purpose Symbolic Instruction Code, a simple programming language widely used for personal computers.
the technique of manufacturing parts or finished goods in groups, lots,
or batches in which each part or finished good in the batch is
is the method adopted when the required product volumes do not allow
continuous production of one product on particular machines.
refers to the lot size of identical parts produced in a factory. Batch
production is the method adopted when the required product volumes are
not adequate to permit continuous production of one product on
A unit of data transmission speed equal to the number of bits (or signal events) per second; 300 baud = 300 bits per second.
a measure of the signalling speed in a digital communication system.
A fixed point of reference or a standard for comparison, used to
achieve excellence within the manufacturing firm; an outstanding
example, appropriate for use as a model.
An improvement process in which a company or organization compares its
performance against best-in-class companies or organizations,
determines how those companies or organizations achieved their
performance levels, and uses the information to improve its own
performance. The subjects that can be benchmarked include strategies,
products/programs/services, operations, processes and procedures.
Bill of material
A listing of all the subassemblies, parts, and raw materials that go into a parent assembly.
Refers to base 2 numbering system, in which the only allowable digits
are 0 and 1. Pertaining to a condition that has only two possible
values or states.
A representation of information using a sequence of zeros and ones. The basis for calculations in all digital computers.
Acronym for basic input/output system. The commands used to tell a CPU how it will communicate with the rest of the computer.
A digit in binary notation, e.g., 0 or 1.
An illustration in which essential units of any system are drawn in the
form of blocks and their relationship(s) to each other are indicated by
appropriate interconnecting lines. (2) In computer programming or
business/manufacturing process flow(s), a graphical representation of
data processing or workflow within a system.
1) A printed-circuit board.
2) A printed-circuit-board assembly
?? in the sense that the (printed-circuit) board is physically the
main component of a printed-circuit-board assembly.
The natural limits of a process, defined as where the process begins and where the process ends.
LAN Uses frequency division multiplexing to divide a single physical
channel into a number of smaller, independent frequency channels to be
used to transfer different forms of information.
A conductor, usually composed of some element of carbon, serving to
maintain an electrical connection between stationary and moving parts
of a machine (i.e.,commutator of a dc motor). This brush is mounted in
a spring-loaded holder and positioned tangent to the commutator
segments against which it "brushes." Pairs of brushes are equally
spaced around the circumference of the commutator.
1) In software terms, a register or group of registers used for
temporary storage of data, to compensate for transmission rate
differences between the transmitter and receiving device. 2) In
hardware terms, an isolating circuit used to avoid the reaction of one
circuit with another.
A programming process that takes a user keyboard command (source code)
and converts it into hexadecimal format to generate an object code for
Bumpless -ability to change processors controlling a process (changeover) without affecting the process.
A high-speed pathway shared by signals from several components of a computer.
A network topology that uses a single communications link to connect three or more terminals. Also called a Multi-Drop Network.
A link topology in which all stations are connected in parallel to a
medium. These stations are capable of concurrently receiving a signal
transmitted by any other station connected to the medium.
(1) A fixed number of bits, often corresponding to a single character
and processed as a unit.
(2) A collection of eight bits capable of
representing an alphanumeric or special character.
