1. Which work cannot be done by Jerome H. Lemelson’s first robot based system?
a) Manufacturing product
b) Welding
c) Inspecting the product
d) Convey the product
Explanation: Manufacturing of product cannot be done by Jerome H. Lemelson’s first robot based system. It can convey the product, inspect it or can even weld two metals. This was the first machine model that was used in industrial sector.
2. FMS (Flexible manufacturing system) consist of a single machine that controls everything.
a) True
b) False
Explanation: FMS (Flexible manufacturing system) does not consist of a single machine that controls everything. It is a cluster of machines that work together to manufacture a product. These machines together form up a system called FMS (Flexible manufacturing system).
3. FMS (Flexible manufacturing system) is not suitable if production quantity is less.
a) True
b) False
Explanation: FMS (Flexible manufacturing system) is not suitable if production quantity is less. FMS (Flexible manufacturing system) is best suited if the production has to be done for a long time and huge amount of goods has to be manufactured.
4. Which does SMC stand for with respect to machine related manufacturing?
a) Single machine control
b) Singular machine control
c) Slot machine cell
d) Single machine cell
Explanation: SMC with respect to machine related manufacturing stands for Single machine cell. It has one CNC (Computer Numerical control) based machine hub that controls all other units. It is also combined with a storage system for unattended operation.
5. The expansion cost of FMS (Flexible manufacturing system) is less.
a) True
b) False
Explanation: The expansion cost of FMS (Flexible manufacturing system) is high. The initial and expansion cost of FMS (Flexible manufacturing system) is high because the advanced machines and systems used in it are costlier than the traditional ones.
6. Which does CNC stand for with respect to machine related manufacturing?
a) Computer Numb control
b) Computer Number control
c) Computer Numerical control
d) Computerised Numerical controller
Explanation: CNC with respect to machine related manufacturing stands for Computer Numerical control. It can control machines such as milling machine, lathe, welding machine etc by taking digital data as its input which is fed into it by the operator.
7. Which is a false statement on CIM (Computer integrated manufacturing)?
a) Quality of the final goods produced is better
b) The cost of production is less
c) Quantity of produced goods can be changed easily
d) The cost of initial setup is less
Explanation: “The cost of initial setup is less” is a false statement on CIM (Computer integrated manufacturing). The labour cost may be less but the cost of setup and its installation is high compared to the traditional ones, because the setup consists of costly and advanced machines.
8. When did the ‘digital manufacturing’ concept became prominent?
a) Early 1950’s
b) Early 1970’s
c) Late 1940’s
d) Late 1960’s
Explanation: The concept of ‘digital manufacturing’ became prominent in the early 1970’s. It became famous after the release of the book “Computer Integrated Manufacturing” written by Dr. Joseph harrington.
9. What is the full form of CAD?
a) Computer aided Design
b) Computer arts Design
c) Computer arts Designing
d) Computer assisted Design
Explanation: CAD stands for Computer aided Design. CAD software is used to digitally design a model. They can create 3-Dimensional model of any desired object. Software such as “Ansys” can even determine stress or strain falling on an object.
10. CIM (Computer integrated manufacturing) system is same as “lights-out factory”.
a) True
b) False
Explanation: CIM(Computer integrated manufacturing) system is not same as “lights-out factory”. In “lights-out factory” there is no requirement of a single human being. Everything is done by the robots. But this is not so in the CIM (Computer integrated manufacturing). Here skilled technicians are needed for the manufacturing.
