PLTW CIM Exam Review Manufacturing has gone from artisans to assembly lines to automation, with a heavy emphasis today on robotics and computers. - Answer -True For Kaizen to work, employees must implement plans and company policy for product improvements without an opportunity to provide input. - Answer -False Which code is used in the same line with the T code? - Answer -M06 Rapid prototyping is usually referred to as: - Answer -Additive Which of the following best describes fixed costs? - Answer -A periodic cost that remains (more or less) unchanged irrespective of the output level or sales revenue of a firm. Which choice best defines an open loop system? - Answer -A control system that has no means for comparing the output with input for control purposes. Which choice best defines an input/output block? - Answer -A function that makes information available for processing or that records processed information. A system that can be reconfigured to do a variety of manufacturing tasks is: - Answer -FMS/Flexible Manufacturing System What is the best answer to "What is CIM?" - Answer -The use of computers on all areas of manufacturing. Flow lines is defined as: - Answer -The connecting line or arrow between symbols on a flow chart. What material is the most valuable today? - Answer -Information. A Closed loop system is - Answer -The system that uses feedback from the input to control the output. A system that eliminates inventory by scheduling arrival of parts and assemblies for an operation at the time they are needed is: - Answer -MRP A potentiometer Is best descibed as: - Answer -A variable resistor. Which choice best defines Control System? - Answer -A system in which one or more outputs are forced to change in a desired manner as time progresses. Non -Value Added is described as - Answer -Typically generates a zero or negative return on the investment of resources and usually can be eliminated without impairing a process. Jervis B. Webb is best known in manufacturing for: - Answer -Electrical coordinated conveyor system. Iterative is the - Answer -Process flow that may repeat or skip steps until some condition is satisfied. Which choice best defines a Process Block? - Answer -Part of a flowchart that tells the program what action to take. Which choice best defines Raw Materials? - Answer -Basic substance in its natural, modified, or semi -
processed state, used as an input to a production process for subsequent modification or transformation into a finished good. Variable cost can be best describe as the following: - Answer -Periodic cost that varies, more or less, in step with the output or the sales revenue of a firm. Such costs include raw material, energy usage, labor (wages), distribution costs, etc. 1 task main() 2 { 3 untilButtonPress(button); 4 wait(0.05); 5 } Why do we use the wait(0.05) command in line #4? - Answer -To overcome any debouncing problems. What external factors should a manufacturer consider? - Answer -Global Economy. Which is the best answer to "What is Lean Manufacturing?" - Answer -The systematic elimination of waste. Eli Whitney's greatest contribution to manufacturing is: - Answer -Interchangeable parts. Which of the following best describe Forging? - Answer -A process by which metal is heated and shaped by plastic deformation by suitably applying compressive force. The number of revolutions per minute (rpm) that is made by the cutting tool of a machine. - Answer -
Spindle Speed Attribute of a feature, such as a dimension, that can be modified. - Answer -Parameter Miscellaneous functions that include actions necessary for machining but are not actual tool movements. - Answer -M Code Codes that carry out machining operations or establish machine settings; G -codes. - Answer -Preparatory Code The process in which a melting metal is injected into the mold under high pressure. - Answer -Die Casting 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. - Answer -Casting A process of pressing moist sand around a pattern to make a mold. The pattern is removed, leaving a cavity in the sand. The cavity is the mold that will be filled with liquid metal. The result will be a casting that is identical in shape to the original pa ttern. - Answer -Sand Casting
