1. “Lights-out factory” is a factory where there is no need any kind of light source.
a) True
b) False
Explanation: “Lights-out factory” is a factory where there is no need any kind of light source. It is also known as “Dark factory”. Every work inside the factory is automated and is carried out by programmed robots.
2. Which does DNC stand for with respect to machine related manufacturing?
a) Direct Numb control
b) Direct Number control
c) Direct Numerical control
d) Directed Numerical controller
Explanation: DNC with respect to machine related manufacturing stands for Direct Numerical control. It is also called as distributed numerical control. In this machines are controlled by a programmed computer with the help of direct connections.
3. Which does PLC stand for with respect to machine related manufacturing?
a) Programmed Logic Controller
b) Programmable Logic Controller
c) Programmed Logic Control
d) Programmable Low-key Controller
Explanation: PLC with respect to machine related manufacturing stands for Programmable Logic Controller. It is used in the control of manufacturing process. It can control the assembly lines, carrier robots etc. It provides ease in programming and in the diagnosis of any fault.
4. What is the full form of CAPP?
a) Computer aided processed plans
b) Computer arts process planning
c) Computer aided process planning
d) Computer assisted process planning
Explanation: CAPP stands for Computer aided process planning. It is the use of computer aided technology to plan or design a product for manufacturing. This process is widely used in CIM (Computer integrated manufacturing) for the planning purpose.
5. Which is an example of PLC (Programmable Logic Controller)?
a) MSP430G2ET
b) CMCP793V-500
c) SR3B261BD
d) BMP180
Explanation: SR3B261BD is an example of PLC (Programmable Logic Controller) developed by SCHNEIDER Electric. BMP180 is a pressure sensor. MSP430G2ET is a development board manufactured by the “TEXAS INSTRUMENTS” and CMCP793V-500 is a velocity sensor.
6. Which software cannot be used for 3D modelling and CAD (Computer aided design)?
a) Creo
b) Ansys
c) Blender
d) Adobe premium pro
Explanation: Adobe premium pro software cannot be used for 3D modelling and CAD (Computer aided design). Creo, Ansys and Blender all three are 3D modeling app which can also be used for CAD (Computer aided design).
7. CIM (Computer integrated manufacturing) implies that there should be at least two computers between which information is interchanged.
a) True
b) False
Explanation: CIM (Computer integrated manufacturing) implies that there should be at least two computers between which information is interchanged. There can be more than two systems which works together and exchange information.
8. Who coined the term CAE (Computer aided engineering)?
a) Jerome H. Lemelson
b) Jason Lemon
c) Charles manes
d) Samuel Hunter Christie
Explanation: Jason Lemon first coined the term CAE (Computer aided engineering). He was the founder of SDRC (Structural Dynamics Research corporation). It was founded in the year 1967.
9. Stress analysis can be performed using “ansys” CAD (Computer aided design) software.
a) True
b) False
Explanation: Stress analysis can be performed using “ansys” CAD (Computer aided design) software. Ansys is a 3D modelling CAD (Computer aided design) software through which we can easily figure out the stress in any part of the object.
10. When was the first attempt of lights-out manufacturing made?
a) 1950
b) 1970
c) 1784
d) 1860
Explanation: The first attempt of lights-out manufacturing made in the year 1784. It was carried out by “Oliver Hans”. He was the one who created the world’s first continuous production line in the year 1784.
