PLTW CIM Study guide
Closed Loop - correct answer ✔A system that uses feedback from the output
to control the input.
Control System - correct answer ✔A system in which one or more outputs
are forced to change in a desired manner as time progresses.
Decision Block - correct answer ✔The diamond-shaped block used for
YES/NO questions. These blocks have two outputs: 1 (for yes) and 2 (for no).
Flow Chart - correct answer ✔A graphical representation of the progress of a
system for the definition, analysis, or solution of a data-processing or
manufacturing problem.
Flow Lines - correct answer ✔The connecting line or arrow between symbols
on a flow chart.
Input/Output Block - correct answer ✔A function that makes information
available for processing or that records processed information.
Interface - correct answer ✔The connection between the computer and the
control system.
Iterative - correct answer ✔Process flow that may repeat or skip steps until
some condition is satisfied.
,Open Loop - correct answer ✔A control system that has no means for
comparing the output with input for control purposes. An open-loop system
often requires human intervention.
Potentiometer - correct answer ✔A variable resistor.
Process Block - correct answer ✔Part of a flowchart that tells the program
what action to take.
Schematic - correct answer ✔A diagram that uses special symbols in place
of actual pictures. In a wiring schematic, for example, a squiggly line is used
to represent a resistor.
Sequential - correct answer ✔Occurring in regular succession without gaps.
Simulation - correct answer ✔A representation of a situation or problem with
a similar but simpler model or a more easily manipulated model in order to
determine experimental results.
AGV - correct answer ✔Automated Guided Vehicle. A computer-controlled
system that uses pallets and other interface equipment to transport work
pieces to NC machine tools and other equipment in a flexible manufacturing
system.
ASRS - correct answer ✔Automated Storage/Retrieval System. A system
that moves material either vertically or horizontally between a storage
compartment and a transfer station or within a process.
Automation - correct answer ✔The use of technology to ease human labor or
extend the mental or physical capabilities of humans.
, CAD - correct answer ✔Computer Aided Design. The use of computers in
converting the initial idea for a product into a detailed engineering design.
CAM - correct answer ✔Computer Aided Manufacturing. The use of
computers in converting engineering designs into finished products.
CIM - correct answer ✔Computer Integrated Manufacturing. A company-
wide management philosophy for planning, integration, and implementation of
automation.
CNC - correct answer ✔Computer Numerical Control. A numerical control
method in which one computer is linked with one machine tool to perform NC
functions.
Dependent Variable - correct answer ✔A variable whose value depends on
the value of another variable.
FMS - correct answer ✔Flexible Manufacturing System. A flexible group of
CNC machine tools that are highly automated and integrated capable of
producing a family of parts.
Independent Variable - correct answer ✔The controlling factor between
variables, on which the value of the other variable depends.
JIT - correct answer ✔Just in Time. A system that eliminates work-in-process
(WIP) inventory by scheduling arrival of parts and assemblies for an operation
at the time they are needed and not before.
