Manufacturing Engineering Multiple Choice Questions on “Reaming”.
1. Helical groves on a body of reamers are known as
a) Flutes
b) Face
c) Heel
d) Recess
Answer: a
Clarification: Flutes are helical grooves present on the body of reamers. They help in better machining process using reamers.
2. In reamers, flute surface adjacent to cutting is known as
a) Flutes
b) Face
c) Heel
d) Recess
Answer: b
Clarification: Face of reamers is adjacent to cutting edge. They help in cutting during machining process using reamers.
3. Small flat surface in between cutting edge and the heel of a reamer is known as
a) Flutes
b) Face
c) Heel
d) Land
Answer: d
Clarification: Land is the small narrow surface between cutting edge and heel. They help in better machining process using reamers.
4. In reamers, edge formed by an intersection of secondary clearance and flute is known as
a) Flutes
b) Face
c) Heel
d) Recess
Answer: c
Clarification: Heel is the edge formed by an intersection of secondary clearance and flute. They help in better machining process using reamers.
5. Reduction in body diameter toward shank of reamer is known as
a) Flutes
b) Face
c) Heel
d) Recess
Answer: d
Clarification: Recess is the reduction in body diameter toward shank. They help in better machining process using reamers.
6. Maximum diameter of reamer at entering is also known as
a) Flutes
b) Face
c) Actual size
d) Recess
Answer: c
Clarification: Actual size of reamer is the maximum diameter of the reamer.
7. Portion of reamer which carries flute is known as
a) Flutes
b) Face
c) Body
d) Recess
Answer: c
Clarification: Body carries flute on it. Face of reamers is adjacent to cutting edge.
8. Tapered of reamer by which it can be gripped is known as
a) Flutes
b) Face
c) Heel
d) Shank
Answer: d
Clarification: Shank is used for gripping reamers and rotating. Face of reamers is adjacent to cutting edge.
9. Longitudinal center line which is concentric with diameter of reamer is known as
a) Flutes
b) Axis
c) Heel
d) Recess
Answer: b
Clarification: Axis divides reamers in two symmetric part.
10. If reamer is found to be cutting while rotating in clockwise direction when viewed against the entering end at a right angle to it is known as
a) Left handed reamer
b) Central reamer
c) Right handed reamer
d) None of the mentioned
Answer: a
Clarification: Left handed reamer rotate in clockwise during cutting when viewed against the entering end at right angle.
11. If reamer is found to be cutting while rotating in anti-clockwise direction when viewed against the entering end at a right angle to it is known as
a) Left handed reamer
b) Central reamer
c) Right handed reamer
d) None of the mentioned
Answer: c
Clarification: Right handed reamer rotate in anti-clockwise during cutting when viewed against the entering end at right angle.
