This set of Machine Tools Multiple Choice Questions & Answers (MCQs) focuses on “Types of Shaper”.
1. According to the type of mechanism used for giving reciprocating motion to the ram, shaper can be classified as______
a) crank type
b) geared type
c) both crank type and geared type
d) none of the mentioned
View Answer
Explanation: According to the type of mechanism used for giving reciprocating motion to the ram, shaper can be classified as both crank type and geared type. Here the ram means the reciprocating member of the shaper which houses a screwed shaft.
2. According to the type of design of the table, lathe can be classified as_____
a) standard shaper
b) universal shape
c) both standard shaper and universal shaper
d) none of the mentioned
View Answer
Explanation: According to the type of design of the table, lathe can be classified as both standar shaper and universal shaper. Standard shaper is also known as plain shaper which has only two movements vertical and horizontal to get feed.
3. Push type shaper is type of shaper according to______
a) design of the table
b) position and travel of the ram
c) type of cutting stroke
d) none of the mentioned
View Answer
Explanation: Push type shaper is type of shaper according to type of cutting stroke. In push type shaper, at the time when the ram is moving away/going away from the column, removal of metal is done.
4. horizontal type shaper is type of shaper according to______
a) design of the table
b) position and travel of the ram
c) type of cutting stroke
d) none of the mentioned
View Answer
Explanation: horizontal type shaper is type of shaper according to position and travel of the ram. When we talk about horizontal shaper, it is mostly used for producing flat surfaces.
5. Draw type shaper is type of shaper according to______
a) design of the table
b) position and travel of the ram
c) type of cutting stroke
d) none of the mentioned
View Answer
Explanation: Draw type shaper is type of shaper according to, type of cutting stroke. In this type of shaper, at the time when the ram is moving towards in the direction of column, the metal removal is done.
6. Travelling head type shaper is type of shaper according to______
a) design of the table
b) position and travel of the ram
c) type of cutting stroke
d) none of the mentioned
View Answer
Explanation: Travelling head type shaper is type of shaper according to, position and travel of the ram. In workshop, if we have a machine that cannot be fixed on the machine or can not be moved at that time we use this shaper.
7. Hydraulic type shaper is type of shaper according to______
a) design of the table
b) position and travel of the ram
c) type of cutting stroke
d) none of the mentioned
View Answer
Explanation: As per the classification of this machine, it can be classified according to the type of mechanism used for giving reciprocal motion to the ram. In hydraulic shaper, not a penny sound is produced. So this shaper machine can be termed as eco friendly machine to some extent.
8. In crank type shaper, for performing an operation a multi point cutting tool is employeed.
a) true
b) false
View Answer
Explanation: This is false. In crank type shaper, for performing an operation a SINGLE point cutting tool is employed. The crank mechanism is used in order to drive reciprocating ram.
9. Vertical type shaper is type of shaper according to______
a) design of the table
b) position and travel of the ram
c) type of cutting stroke
d) none of the mentioned
View Answer
Explanation: Vertical type shaper is type of shaper according to position and travel of the ram. In vertical type shaper ram has its motion in vertical direction, that’s why it is known as vertical shaper.
10. The shaper is a reciprocating type of machine tool primarily intended for producing flat surfaces.
a) true
b) false
View Answer
Explanation: As per the definition of this machine. It is a reciprocating type machine introduced by James Nasmyth in 1836 for producing flat surfaces.
