1. The method of grinding used to produce a straight or tapered surface on a work piece is called – (a) Internal cylindrical grinding, (b) external cylindrical grinding, (c) form grinding, (d) surface grinding.
Ans. (b) external cylindrical grinding.
2. The method of grinding used to produce internal cylindrical holes surface on a work piece is called – (a) Internal cylindrical grinding, (b) external cylindrical grinding, (c) form grinding, (d) surface grinding.
Ans. (a) Internal cylindrical grinding.
3. In transverse grinding –
(a) the work is reciprocated as the wheel feeds to produce cylinders longer than width of the wheel face,
(b) the work rotates in a fixed position as the wheel feeds to produce cylinders equal to shorter than width of the wheel face,
(c) the work is reciprocated as the wheel feeds to produce cylinders shorter than width of the wheel face,
(d) the work rotates in a fixed position as the wheel feeds to produce cylinders longer than width of the wheel face.
Ans. (a) the work is reciprocated as the wheel feeds to produce cylinders longer than width of the wheel face.
4. In plunge grinding –
(a) the work is reciprocated as the wheel feeds to produce cylinders longer than width of the wheel face,
(b) the work rotates in a fixed position as the wheel feeds to produce cylinders equal to shorter than width of the wheel face, (c) the work is reciprocated as the wheel feeds to produce cylinders shorter than width of the wheel face,
(d) the work rotates in a fixed position as the wheel feeds to produce cylinders longer than width of the wheel face.
Ans. (b) the work rotates in a fixed position as the wheel feeds to produce cylinders equal to shorter than width of the wheel face.
5. The grinding of long slender shafts or bars is usually done by – (a) infeed grinding, (b) through feed grinding, (c) end feed grinding, (d) any one of these.
Ans. (b) through feed grinding.
6. The infeed grinding used to grind – (a) tapers, (b) shoulder & formed surfaces, (c) long & slender shafts, (d) all of these.

7. In center-less grinding taper is produced by – (a) infeed grinding, (b) through feed grinding, (c) end feed grinding, (d) any one of these.
Ans. (b) through feed grinding.
8. In grinding irregular, tapered, curved, convex & concave surfaces, the grinder used is – (a) Cylindrical Grinder, (b) internal grinder, (c) surface grinder, (d) tool & cutter grinder.
Ans. (c) surface grinder.
9. The size of abrasive grain required in grinding wheel depends on – (a) amount of material to be removed, (b) hardness of a material being ground, (c) finish desired, (d) any one of these.
Ans. (b) hardness of a material being ground.
