This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Error Detection and Recovery”.
1. Which error occurs as result of normal stochastic nature of the process?
a) Systematic Errors
b) Aberration Errors
c) Random Errors
d) Redundant Error
View Answer
Explanation: The Type of error which occurs as a result of normal stochastic nature of the process is known as random errors. Large amount of errors in this can cause serious problem in downstream operations.
2. Which type of error occurs as result of change in raw material or drift in equipment setting?
a) Aberration Errors
b) Absolute Errors
c) Random Errors
d) Systematic Errors
View Answer
Explanation: The Type of error which occurs as a result of change in raw material or drift in equipment setting is known as systematic error. It usually occurs from an assignable cause.
3. Which type of error occurs as result of equipment failure or human mistake?
a) Random Errors
b) Absolute Errors
c) Systematic Errors
d) Aberration Errors
View Answer
Explanation: The Type of error which occurs as a result of equipment failure or human mistake is known as aberration error. This may occur due to the mistake in programming the equipment or failure of shear pin.
4. Which category does the possible errors such as loss of power and chip fouling come under?
a) Part Storage Unit
b) Machine and Process
c) Cutting Tools
d) Load/Unload Robot
View Answer
Explanation: The possible errors such as loss of power, chip fouling, power overload, thermal deflection and wrong part program come under the category of machine and process.
5. Which category do the possible errors such as tool breakage and tool wear out come under?
a) Part Storage Unit
b) Machine and Process
c) Cutting Tools
d) Load/Unload Robot
View Answer
Explanation: The possible errors such as tool breakage, tool wear and wrong tool fall under the category of cutting tools. Part Storage Unit, Cutting Tools and Load/Unload Robot do not fall under the category of the possible errors such as tool breakage and tool wear.
6. Which category do the possible errors such as dislodging of part during machining fall under?
a) Part Storage Unit
b) Work holding Fixture
c) Cutting Tools
d) Load/Unload Robot
View Answer
Explanation: The possible errors such as dislodging of part during machining fall under the category of work holding fixture error. Part Storage Unit, Cutting Tools and Load/Unload Robot do not fall under the category of possible errors such as dislodging of part during machining.
7. Which category do the possible errors such as oversized or undersized part fall under?
a) Part Storage Unit error
b) Machine and Process error
c) Cutting Tools error
d) Load/Unload Robot error
View Answer
Explanation: The possible errors such as oversized or undersized part fall under the category of Part Storage unit error. Machine and Process error, Cutting Tools error and Load/Unload Robot error do not fall under the category of the possible errors such as oversized or undersized part.
8. Which category do the possible errors such as improper grasping of work part fall under?
a) Part Storage Unit error
b) Machine and Process error
c) Cutting Tools error
d) Load/Unload Robot error
View Answer
Explanation: The possible errors such as improper grasping of work part fall under the category of Load/Unload Robot error. Part Storage Unit error, Machine and Process error and Cutting Tools error do not fall under the category of possible errors such as improper grasping of work part.
9. Which is concerned with applying the necessary corrective action to overcome the error?
a) Error Recovery
b) Part Recovery
c) Tool Recovery
d) Operator Recovery
View Answer
Explanation: The process which is concerned with applying the necessary corrective action to overcome the error is known as error recovery. This helps in bringing back the system to the normal operation.
10. Making adjustments at the end of the work cycle executes the subroutine and is commonly associated with the random errors.
a) True
b) False
View Answer
Explanation: Making adjustments at the end of the work cycle executes the subroutine and is commonly associated with the random errors. It is commonly observed in automated and semi automated systems in order to achieve the required production target.
