## 250+ TOP MCQs on Lathe : Working Principle and Answers

Machine Tools Multiple Choice Questions on “Lathe Working Principle”.

1. Which machine tool is known as the mother machine tool?

a) drill b) milling c) lathe

d) none of mentioned

Clarification: Lathe is known as the mother machine tool because it

can perform various type of operations. It is a versatile machine.

2. Lathe is primarily used for producing ____surfaces.

a) flat b) curve c) taper

d) none of the mentioned

Clarification: Lathe is primarily used for producing cylindrical surfaces. But today it can perform various operations and perform various surfaces like curvilinear surface, flat surface and so on.

3. Which type of surface is produced by turning operation in lathe machine?

a) flat b) cylindrical c) taper

d) none of the mentioned

Clarification: Cylindrical surface is produced by turning operation in lathe machine. This turning can be done on the external surface. Boring is a type of turning which is performed in the internal surface.

4. What is the necessary condition for turning?

a) material of work piece should be harder than the cutting tool

b) cutting tool should be harder than the material of work piece

c) hardness of the cutting tool and material of of piece should be same

d) none of the mentioned

Clarification: Cutting tool should be harder than the material of work piece, so that it can be able to cut the work piece into the desire shape.

5. Traversing of tool parallel to the axis of job is termed as_____

a) cross feed

b) longitudinal feed

c) both cross feed and traversing feed

d) none of the mentioned

Clarification: It is the definition of longitudinal feed. Similarly, traversing of tool perpendicular to the axis of job is known as cross feed.

6. The swing diameter over the bed is the largest diameter.

a) true b) false Answer: a

Clarification: This is true. Swing diameter over the lathe is the largest diameter of work over the bed that will revolve without touching height of the centres measured from the bed of the lathe.

7. Lathe cannot produce internal features like holes.

a) true b) false Answer: b

Clarification: This is false. Lathe is a versatile machine tool. It can produce holes, flat surfaces and so on.

8. Which type of feed is needed in facing operation?

a) longitudinal b) cross

c) both cross and longitudinal

d) none of the mentioned

Clarification: Facing operation is done by the cross feed. In facing, workpiece is rotated against the single point cutting tool.

9. Which type of surface is produced in facing operation?

a) cylindrical b) taper c) flat

d) none of the mentioned

Clarification: Flat surface is produced in facing operation as per the definition. In facing operation, metal is removed by the tool from thee end of the metal and flat surface is produced.

10. Traversing of tool at any angle to the job axis produces curve surfaces.

a) true b) false Answer: b

Clarification: This is false. Traversing of tool at any angle to the job axis produces taper surfaces.

11. In taper operation, which type of surface is produced?

a) flat b) curve c) circular

d) none of the mentioned

Clarification: Taper type surface is produced in the process of taper turning. Taper is a shape in which the diameter of the both ends of bar are different.

12. Which type of feed is needed in turning operation?

a) longitudinal b) cross

c) both cross and longitudinal

d) none of the mentioned

Clarification: As per definition, longitudinal feed is needed in turning operation. Longitudinal feed is always parallel to the axis of rotation of the spindle.

13. Which type of surface can be produced by lathe?

a) flat b) cylindrical c) curvilinear

d) all of the mentioned

Clarification: Lathe is a versatile machine. It can perform various types of jobs. It is primarily intended for producing only cylindrical surface but it can produce various types of surfaces.
