Sample ME8451 Important Questions Manufacturing Technology 2 :

1. What is rake angle? What is the effect of nose radius in tools?
The angle between the tool face and the line parallel to the base of the tool is
known as side rake angle. It is used to control chip flow.

2. What is tool? (ME8451 Important Questions Manufacturing Technology 2)
The various angles of tools are mentioned in a numerical number in particular
order. That is known as tool signature.

3. Explain the nose radius? (ME8451 Important Questions Manufacturing Technology 2)
It is the joining of side and end cutting edges by means of small radius in order to
increase the tool life and better surface finish on the work piece.

4. Name the factors that contribute to poor surface finish in cutting?
Cutting speed
Feed
Depth of cut.

5. What is orthogonal cutting?
The cutting edge of tool is perpendicular to the work piece axis

6. Define oblique cutting? (ME8451 Important Questions Manufacturing Technology 2)
Oblique cutting: – The cutting edge is inclined at an acute angle with normal to the
cutting velocity vector is called oblique cutting process

9. What is the function of chip breakers?
The chip breakers are used to break the chips into small pieces for removal, safety
and to prevent both the machine and work damage

10. Define machinability of metal?
Machinability is defined as the ease with which a material can be satisfactorily
machined

11. How tool life is defined? (ME8451 Important Questions Manufacturing Technology 2)
Tool life is defined as the time elapsed between two consecutive tool
resharpening. During this period the tool serves effectively and efficiently

9. What is the purpose of mandrel? How many types of mandrels is there in
common use? (ME8451 Important Questions Manufacturing Technology 2)
Mandrels are used for holding hollow work pieces.
1. plain mandrel
2. collar mandrel
3. cone mandrel
4. special mandrel
5. step mandrel
6. Expansion mandrel
7. Gang mandrel
