This set of Machine Tools Multiple Choice Questions & Answers (MCQs) focuses on “Shaper Basics – 2”.
1. The front of the body provides guideways for _______
a) ram
b) crossrail
c) can’t say anything
d) none of the mentioned
View Answer
Explanation: The front of the body provides guideways for crossrail . Crossrail has two parallel guideways on its top in the vertical plane.
2. The crossrail is mounted on the______ of the body frame
a) front
b) back
c) can’t say anything
d) none of the mentioned
View Answer
Explanation: The crossrail is mounted on the front of the body frame. Crossrail can slide up and down in the vertical frame.
3. The ram can be moved up and down.
a) true
b) false
View Answer
Explanation: These both movements are possible in the ram. It houses a screwed shaft for altering the position of ram.
4. The _______ movements of crossrail permit the jobs of different heights to be accommodated below the tool.
a) horizontal
b) vertical
c) can’t say anything
d) none of the mentioned
View Answer
Explanation: The vertical movements of crossrail permit the jobs of different heights to be accommodated below the tool. The table may be raised or lowered to accommodate different sizes of job by rotating an elevating screw which causes the crossrail to slide up and down.
5. Saddle carries the work table.
a) true
b) false
View Answer
Explanation: This is true. It carries the table which can be raised or lowered to accommodate different sizes.
6. Which movement of ram is called stroke?
a) only back
b) only forth
c) back and forth
d) none of the mentioned
View Answer
Explanation: Back and forth movement of ram is called stroke, but only in forward stroke useful work is done.
7. The stroke can be adjusted according to the length of the workpiece to be machined.
a) true
b) false
View Answer
Explanation: This is true. Two strokes are there: forward stroke and return stroke. Time for forward stroke should be more than return stroke for better performance.
8. The ram is driven back and forth in its slides by crank slider mechanism.
a) true
b) false
View Answer
Explanation: This is false. The ram is driven back and forth in its slides by slotted link mechanism.
9. Shaper can produce contours of ______
a) concave
b) convex
c) both concave and convex
d) none of the mentioned
View Answer
Explanation: Shaper can produce contours of both concave and convex. There are some contour type shapers which are fixed by an additional mechanism known as tracer mechanism.
10. Shaper can produce flat surface only in horizontal and vertical plane, not in angular plane.
a) true
b) false
View Answer
Explanation: This is false. Shaper can produce flat surface in all horizontal ,vertical and angular planes. This is the main purpose shaper. It is primarily intended for the purpose of producing flat surfaces.
