This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Manufacturing Operations – Set 2”.
1. Which process is used to remove excess material to get the desired geometry?
a) Lubricating
b) Particulate Processing
c) Material Removal Process
d) Welding
View Answer
Explanation: Material Removal Process is used to remove excess material from the part to get the desired geometry. In general, ductile or brittle metal is used in the material removal process. The starting material is solid in nature.
2. Which is a material removal process?
a) Milling
b) Bending
c) Embossing
d) Coining
View Answer
Explanation: Milling is a material removal process. Bending, Embossing and Coining are sheet metal operations. Milling is a process in which rotating milling tool is fed against either stationary or sliding work piece.
3. Which of the following is a non-traditional process?
a) Drilling
b) Electron Beam Machining
c) Shaping
d) Grinding
View Answer
Explanation: Electron Beam Machining is a non-traditional process. Drilling, Shaping and grinding are the conventional machining process. In Non-traditional approach, the usual method of feeding the tool against the work piece is eliminated with the recent machining technologies.
4. Which process builds the part by sequence of adding thin layers on top of the surface?
a) Feasible Manufacturing
b) Structural Manufacturing
c) Subtractive Manufacturing
d) Additive Manufacturing
View Answer
Explanation: Additive manufacturing process involves building thin layer as a sequence on top of the surface in order to build a final part. It is also known as Rapid prototyping. Variety of material types can be manufactured using this technique.
5. Which operation involves heat treatments and toughening process to enhance the property of the material?
a) Welding
b) Property Enhancing Operation
c) Painting
d) Assembling Operation
View Answer
Explanation: Property Enhancing Operations involve heat treatments and toughening process to enhance the properties of the material. Both mechanical and physical properties of the material are enhanced using this operation.
6. What are all the categories of Processing Operations?
a) Setting, Tooling and Dismantling
b) Shaping, Property Enhancing and Surface Processing
c) Dismantling, Assembling and Machining
d) Manufacturing, Dismantling and Assembling
View Answer
Explanation: Shaping, Property Enhancing and Surface Processing are the three broad categories of Processing Operations. These operations are usually done is sequence to achieve the required design specifications.
7. Which of the following is a permanent joint?
a) Rivets
b) Screws
c) Bolts
d) Nuts
View Answer
Explanation: Rivets is a permanent joint. Screws, bolts and nuts are Temporary joints. Rivet is done using metal plate known as die against which the metal is applied force which gain the shape of the die and results in a permanent joint.
8. Which process is widely used in electronics assembly equipments?
a) Rivet
b) Expansion fits
c) Soldering
d) Press Fitting
View Answer
Explanation: Soldering is widely used in electronics assembly equipments. Rivet, Expansion and Press fits are permanent joints exclusively used to join two parts permanently without any relative motion in between them.
9. Which joint can be dismantled easily?
a) Relative Joint
b) Stable Joint
c) Permanent Joint
d) Temporary Joint
View Answer
Explanation: Temporary joints can be dismantled easily. Conventional fasteners like Screws, bolts and nuts are the typical examples of temporary joints. They are used in applications where the broken part can be easily replaced by dismantling the assembly.
10. Which process examines whether the actual parts meet the desired design parameters?
a) Coordinating
b) Inspection
c) Material Handling
d) Material Storing
View Answer
Explanation: The process where the actual parts are checked with the desired design parameter is known as Inspection. It involves examining the parameters such as dimensions and tolerances of the actually manufactured mechanical parts.
