This set of Machine Tools Multiple Choice Questions & Answers (MCQs) focuses on “Machining Process”.
1. Why metal removal process is costly?
a) more energy is required
b) some of the material is wasted
c) both more energy is required and some of the material is wasted
d) none of the mentioned
View Answer
Explanation: As we require more energy, cost will definitely increase and again some material is also removed(lost) in this process.
2. In which machining process, removed metal is negligible?
a) surface finishing
b) metal removal
c) both surface finishing and metal removal
d) none of the mentioned
View Answer
Explanation: Metal which is removed, is more (can’t negligible) in case of metal removal process but in surface finishing metal removal is negligible.
3. Dimension accuracy is not affected in metal removal process?
a) true
b) false
View Answer
Explanation: This is false. Accuracy of dimension is not affected in surface finishing process.
4. Which of the following process is not grouped under metal removal process?
a) boring
b) milling
c) tumbling
d) rolling
View Answer
Explanation: Only boring and milling are grouped under metal removal process. Tumbling is the type of surface finishing process.
5. Which of the following is not groped under the surface finishing process?
a) sawing
b) tapping
c) buffing
d) polishing
View Answer
Explanation: Only tapping, buffing and polishing are grouped under surface finishing process. Sawing is the type of metal removal process.
6. Metal removal process gives poor contour on the compound.
a) true
b) false
View Answer
Explanation: This is false. Metal removal process gives poor contour on the compound.
7. In how many groups, metal removal process can be classified?
a) 2
b) 3
c) 4
d) 5
View Answer
Explanation: Metal removal process can be classified as conventional machining, abrasive process and nontraditional machining.
8. In which type of metal removal process, grinding is included?
a) conventional machining
b) abrasive process
c) nontraditional machining
d) none of the mentioned
View Answer
Explanation: As per the classification of metal removal process, it is included in abrasive process. When we remove metal with the help of single or multiple abrasive particle, the process is called abrasive process.
9. ______ metal removal process includes milling.
a) conventional machining
b) abrasive process
c) nontraditional machining
d) none of the mentioned
View Answer
Explanation: As per the classification of metal removal process, it is included in conventional process. Conventional machines are machines which requires human efforts and that are not fully automated. Metal removal process need some human efforts.
10. In which type of metal removal process, thermal energy is included?
a) conventional machining
b) abrasive process
c) nontraditional machining
d) none of the mentioned
View Answer
Explanation: It is included in nontraditional machining. Thermal energy is an energy which is generated from the heat like kinetic energy of molecule, chemical energy of particle and so on.
11. Which of the following is the type of nontraditional machining?
a) turning
b) drilling
c) milling
d) none of the mentioned
View Answer
Explanation: Turning, drilling and milling are the types of nontraditional machining. Drilling means make a hole by using drilling machine and milling machine is a machine tool that removes metal as the work is fed against multipoint cutter. Turning is basic operation generally carried out on lathe machine.
12. In which metal removal process, material is removed by particles?
a) conventional machining
b) abrasive process
c) nontraditional machining
d) none of the mentioned
View Answer
Explanation: It can be understood from the definition of abrasive process. Like in abrasive water jet operation, material is removed by erosion.
13. In which process, various energy forms other than sharp cutting tool is used to remove materials?
a) conventional machining
b) abrasive process
c) nontraditional machining
d) none of the mentioned
View Answer
Explanation: It can be understood from the definition of nontraditional machining. Non-traditional machining is an operation which do not use shear as their primary sources of energy.
14. Metal removal process is also termed as primary production process.
a) true
b) false
View Answer
Explanation: This is false. Metal removal process is also termed as secondary production process.
15. Which of the following is not the type of nontraditional machining?
a) electrochemical process
b) chemical machining
c) mechanical energy process
d) none of the mentioned
View Answer
Explanation: Electrochemical process, chemical machining and mechanical energy process are all the types of nontraditional machining. Apart from these, photochemical, chemical milling, ultrasonic machining, laser beam machining etc. are also the type of nontraditional machines.
