# MCQs on Indexing by Milling

1 - Question

Dividing head is generally used for changing the angular position of work piece relative to milling cutter.
a) True
b) False
Explanation: Indexing head are also known as dividing head and are used for changing angular position of work piece relative to milling cutter.

2 - Question

Which of the following is precision dividing head used in milling?
d) None of the mentioned
Explanation: Optical dividing heads are precision heads and are used in precision indexing work. Indexing head are also known as dividing head and are used for changing angular position of work piece relative to milling cutter.

3 - Question

Circumference of a work piece is to be divided in 8 equal division using index plate of 24 slots. Indexing ratio is equal to
a) 2
b) 3
c) 4
d) 6
Explanation: Indexing ratio = (number of slots on index plate)/ (number of division required). Hence indexing ratio is equal to 3. advertisement

4 - Question

Circumference of a work piece is to be divided in 10 equal division using an index plate of 550 slots. Indexing ratio is equal to
a) 2
b) 3
c) 5
d) 6
Explanation: Indexing ratio = (number of slots on index plate)/ (number of division required). Hence indexing ratio is equal to 3.

5 - Question

Circumference of a work piece is to be divided into 60 equal divisions using simple indexing method having 40 worm wheel teeth. Indexing movement will be
a) 12 holes on 18 hole circle
b) 16 holes on 18 hole circle
c) 12 holes on 21 hole circle
d) 16 holes on 21 hole circle
Explanation: Indexing movement = (40)/ (number of division required).Hence indexing movement is equal to 12 holes on 18 hole circle.

6 - Question

Circumference of a work piece is to be divided into 35 equal divisions using simple indexing method having 40 worm wheel teeth. Indexing movement will be
a) 3 holes on 18 hole circle
b) 16 holes on 18 hole circle
c) 3 holes on 21 hole circle
d) 16 holes on 21 hole circle
Explanation: Indexing movement = (40)/ (number of division required). Hence indexing movement is equal to 3 holes on 21 hole circle.

7 - Question

Circumference of a work piece is to be divided into 6 equal divisions using direct indexing method. Indexing movement will be
a) 5
b) 2
c) 3
d) 4
Explanation: Indexing movement = (24)/ (number of division required). Hence indexing movement is equal to 4.

8 - Question

Circumference of a work piece is to be divided into 12 equal divisions using direct indexing method. Indexing movement will be
a) 5
b) 2
c) 3
d) 4
Explanation: Indexing movement = (24)/ (number of division required). Hence indexing movement is equal to 2.

9 - Question

What will be the index movement to mill a hexagon head screw by using direct indexing?
a) 2
b) 3
c) 4
d) 6
Explanation: For direct indexing, indexing movement = (24)/ (number of division required). Hence indexing movement is equal to 4.

10 - Question
