This set of Machine Tools and Machining Problems focuses on “Parts of Standard Shaper”.
1. Standard shaper is also known as plain shaper.
a) true
b) false
View Answer
Explanation: As per the definition of standard shaper. This shaper uses a linear tool path for machining.
2. A shaper is termed as standard when the table has _____ movements.
a) only one
b) only two
c) only three
d) none of the mentioned
View Answer
Explanation: This is the definition of standard shaper. Other types of shaper are horizontal shaper, draw-cut shaper, universal shaper etc.
3. Which type of movements of table can be given to the feed?
a) horizontal
b) vertical
c) horizontal or vertical
d) none of the mentioned
View Answer
Explanation: Both horizontal and vertical table movements can be given to feed. Linear relative motion between a work piece and single point cutting tool is given.
4. The table must be supported at the outer end.
a) true
b) false
View Answer
Explanation: It is not compulsory that the must be supported at the outer end. It may or may not be supported at outer end.
5. The base of standard is made of cast iron.
a) true
b) false
View Answer
Explanation: As per the construction of shaper machine, it may be made of cast iron as it provide great strength and stability.
6. The base of the standard shaper is able to_____
a) resist vibration
b) take up high compressive
c) both resist vibration and take up high compressive
d) none of the mentioned
View Answer
Explanation: This is the property of standard shaper’s base. As it is made of cast iron and other strong component it has these properties.
7. The base may be rigidly bolted to the floor of the shop or on the bench according to the size of the machine.
a) true
b) false
View Answer
Explanation: As per the construction of standard shaper. This type of arrangement of base provide great stability to machine and make the machine more suitable for its purpose.
8. Which of the following is a box like casting mounted up on the base.
a) column
b) crossrail
c) toolhead
d) none of the mentioned
View Answer
Explanation: Column is situated on the base so we can feel that it is a box like casting mounted up on the base because of its arrangement.
9. Which of the following encloses the ram drive mechanism?
a) crossrail
b) toolhead
c) saddle
d) none of the mentioned
View Answer
Explanation: Column encloses the ram drive mechanism. This ram can be adjusted for stroke. It can move faster in return stroke due to its geometry.
10. The ram reciprocates on the top of the column.
a) true
b) false
View Answer
Explanation: This is true. In ram movement, due to slotted link, ram move faster in case of return stroke as compare to forward stroke..
11. How many machined guideways are provided on the top of the column?
a) one
b) two
c) four
d) none of the mentioned
View Answer
Explanation: Two guideways are provided. Guideways are like a tracko or path along with simething move.
12. The _____ face of the column serves as the guideways for the crossrail.
a) front horizontal
b) back horizontal
c) front vertical
d) back vertical
View Answer
Explanation: Front vertical face serves as the guideways for the crossrail.
13. The ram is reciprocating member of the shaper.
a) true
b) false
View Answer
Explanation: It is the property of ram. Its speed is high in case of return stroke and low in forward stroke.
14. Which type of feed movements of tool does the toolhead provide?
a) vertical
b) angular
c) both vertical and angular
d) none of the mentioned
View Answer
Explanation: Toolhead provides these both feed movements of tool. Shaper toolhead is made of the clapper box, clapper block, toolpost and hinge pin.
15. The toolhead allows the tool to have an automatic relief during its return stroke.
a) true
b) false
View Answer
Explanation: It is the function of the toolhead. It works like an apron.
