5. Which type of feed is always done perpendicular to the axis of work?
a) longitudinal feed
b) angular feed
c) cross feed
d) none of the mentioned
View Answer
Explanation: Cross feed is always done perpendicular to the axis of the work as per the classification of carriage movements. Cross feed is done with the help of the cross-slide movement.
6. Which of the following is not true for compound rest?
a) the swivel base is provided with a dovetail on its bottom surface
b) the top slide has dovetail groove
c) the assembly of the top slide to the swivel base is done by a tapered jib
d) none of the mentioned
View Answer
Explanation: All the sentences are true except the one which says that the swivel base is provided with a dovetail on its bottom surface. The swivel base is provided with a dovetail on its top surface.
7. Taper jib can be adjusted to control the swivel base movements.
a) true
b) false
View Answer
Explanation: This is false. Taper jib can be adjusted to control top slide movements.
8. Which of the following is not true?
a) sliding over the bed is done by the operation of the hand wheel in saddle
b) the top of the cross slide has got a dovetail groove machined
c) the sliding of the top slide on the swivel bas is accomplished
by the help of a screw-rod
d) none of the mentioned
View Answer
Explanation: All the sentences are true except the one which says that the top of the cross slide has got a dovetail groove machined. The bottom of the cross slide has got a dovetail groove machined.
9. In compound rest, the screw-rod is fitted with_____
a) a hand wheel
b) a graduated collar
c) a hand wheel and a graduated collar both
d) none of the mentioned
View Answer
Explanation: These both are used for the fitting of the screw-rod. The sliding of the top slide on the swivel base is accomplished by the help of this screw-rod.
10. Which type of feed is necessary for the function of the cross slide?
a) hand feed
b) automatic feed
c) either by hand feed or by automatic feed
d) none of the mentioned
